海外TECH	DEV Community	6 Big mistakes most beginner software engineers make 🙁 - I wish I knew this when I started programming 😢	https://dev.to/turinumugisha_s/6-big-mistakes-most-beginner-software-engineers-make-i-wish-i-knew-this-when-i-started-programming-5h98	Big mistakes most beginner software engineers make I wish I knew this when I started programming Every master was once a beginner And every pro began as an amateur quote by Robin SharmaAs Robin sharma quoted none is a master that was not a beginner What only differenciate a beginner from a master is the experience gained through all the journey Getting started into programming can be thought as something simple as well as you have your PC and access to all the materials needed to get started but the more time you spend into it the more your eyes get opened and realize all the stupid things you ve done and the time you ve wasted When i started programming I did big mistakes that I wish I had got someone to alert me about them before I got started I ve also seen alot of beginners that I tutored trying to do the same all the times I lost alot of money and time that I don t wish anyone else to loose In this tutorial I will be sharing you these mistakes and how you can avoid them if you are just getting started or have started already but have the same bad habits Trying to learn alot of things at onceWhen I was getting started I had what we call FOMO Fear Of Missing Out and its something I see in alot of young developers these days where they want to be up to date to each latest trend in Software Engineering By the time You could find me learning more than languages at once and even jumping to more advance concepts and framworks before I knew the fundamentalsAt the end of it all I knew it was just a wastage of time because how this industry is set none hires you because you just know alittle of many trending technologies No Companies need someone who master a certain language and is probably the best at it Please please don t rush Focus on one language and start from fundamental concepts not just rushing to advanced ones or frameworks This will not only make you a master at that language but also make it simple for you when you try to learn something else Jumping into code too quick Coding without planningThis is the most common mistake of programmers that they write code without thinking and planning As a beginner engineer you have so much excitement to code and nothing else If you are the kind that jumping to code is the first idea or solution that comes to your mind when you get a problem to solve you will end up wasting a lot of your time Resist the temptation to code and think about alternate ways to challenge your own assumptions first Yes some of this comes with experience but it s good to build the habit early on It applies to both small applications and large applications You require to think and plan in advance before coding and this is a rule The correct process to write quality code is Research Plan Write Validate Modify Googling issueI categorize googling issue into two things The first issue that s much common to absolute beginners is not knowing to search for what they need They waste their time in solving a problem when they can google it and find a solution to a problem Google helps you to understand that what you think is a problem is not really a problem and stop fixing it So Google it first Being creative sometimes doesn t mean everything you are doing is correct The second issue is using search the bad way this is that you search for something because you are stuck and need some help But the moment you find a post that gives you the solution you just copy paste it and move on without understanding how they solved it and why you could not You solved your immediate problem but you didn t fix the root cause This is very dangerous because it leads you to become the kind of engineer that solves problems in a very hacky and patched up manner without understanding the actual inner workings of your own solution Please use that keyboard wisely Don t be the stackoverflow dev It s okay to look for solutions online but when you find one make sure to fully understand how it works and to fill gaps in your own knowledge that led you to being stuck in the first place Preferring quantity to qualityAmbiguous code is waste and it cannot re create While programming or coding focus should be kept on the quality of the code By quality I mean code should be readable and clean Don t repeat yourself and Don t feal eargered to clear ambiguous code because you think it took you a long time to write If you don t focus one code quality and just code you can t stand out for sure Being to working doesn t mean its optimized Optimize your code again and again till they reach the best standard Just picking a solution because it s probably the firstThis point is connected to the fourth one While you might think your first searched solution is all inviting and true good solutions are found after evaluating all possible solutions you find Coders should be able to find multiple solutions to a problem If you are unable to do so that means you do not understand the problem As a programmer you need to find a solution that is simple enough to read understand and maintain Instead of rushing towards implementation think about the potential failures of the solutions and try to find the solutions of a problem in the simplest way Not reading others codeThis is so common it s not even for absolute beginners only I ve seen great devs who can code up quick effective solutions on their own but completely crumble when they have to contribute to any project that is not their own The reason is they are just not used to reading other people s code Reading other people s code understanding it quickly and being able to debug through it is a skill on it s own So start building this early because you will be doing a lot of this in your job and reading others code can sometimes be more challenging than writing your own The end goal as you progress through your career is to not only be able to read a codebase that multiple devs have worked on but understand the big picture quickly and identify areas where you can improve A great way to build this skill early on is to go to open source projects read the code there and try to understand what is going on Even better if you can identify some improvements and put in a pull request to do so I just want to keep this article short Let me conclude ConclusionYou might be worried that you are making alot of mistakes after reading this article But don t panic It s just a part of the journey The only bad thing you can do is persisting on not correcting what you ve seen as a mistake Stop worrying about best practices and focus on what you can do best Invest enough time in research and find good practices that suit well for programming Do not go looking for best practices on the basis of what others found Best practices come from own research and practices Rely on self searched steps for quality coding Every content is different from others and every good practice does not necessarily apply to all Done Boom We are done its your turn now to share us what you think about the article and any mistake that you might have done that you think others should avoid Stay tunned Bye	2022-08-08 13:16:02
海外TECH	DEV Community	[PT-BR] Functional Interfaces, a fundação para a programação funcional com Java	https://dev.to/dearrudam/pt-br-functional-interfaces-a-fundacao-para-a-programacao-funcional-com-java-3c0e	PT BR Functional Interfaces a fundação para a programação funcional com JavaNo último post vimos como implementar o pattern EAM Execute Around Method no Java através das Lambdas Expressions e vimos também que esse pattern utiliza um dos pilares da programação funcional chamado Higher order functions para prover a sua solução Éatravés dos objetos de função podemos aplicar o pilar Higher order functions no Java pois podemos Passar objetos de função como argumentos nos métodos Criar objetos de função dentro dos métodos e Retornar objetos de função de métodos Para escrever códigos que interajam com qualquer objeto isso inclui os objetos de função precisamos conhecer o seu tipo o seu contrato Comumente utilizamos interfaces para definir esse contrato que éonde definimos os métodos que podemos chamar das instâncias baseadas nas classes que implementam esse tal contrato O mesmo acontece quando queremos interagir com uma váriavel precisamos conhecer qual éo seu tipo Inevitavelmente ao escrever nossos métodos precisamos definir em suas assinaturas os tipos dos argumentos que ele suporta e se caso retornem algum objeto precisamos também declarar qual éseu tipo O mesmo se aplica a métodos que recebem ou devolvam objetos de função isto é seránecessário declarar seu tipo a sua interface Objetos de função que são criados através de lambda expressions ou method references sim vamos ver isso no futuro devem implementar interfaces especiais as interfaces funcionais Functional Interfaces As interfaces funcionais são interfaces que tem um único método abstrato para ser implementado e que podem ou não ter vários métodos estáticos ou default methods que estão implementados na própria interface Interfaces bem conhecidas Runnable Callable Comparable entre outras que combinam com essa essa definição são também tratadas como interfaces funcionais Vocêpode ficar atentado a criar suas interfaces funcionais mas uma boa prática éutilizar as interfaces funcionais padrão fornecidas pelo pacote java util function uma vez que alguma atenda sua necessidade As interfaces funcionais são a fundação para a utilização das Lambdas Expressions e Method References Conhecendo as interfaces funcionais mais utilizadas A biblioteca padrão do Java tem aproximadamente interfaces funcionais no pacote java util function para facilitar a vida do desenvolvedor Abaixo podemos conferir uma lista com seis interfaces básicas que frequentemente iremos encontrar e por esse motivo éimportante ficarmos familiarizados com elas Consumer lt T gt Supplier lt T gt Predicate lt T gt Function lt T R gt UnaryOperator lt T gt BinaryOperator lt T gt TL DRHátambém três variantes para cada uma dessas seis interfaces funcionais básicas que operam com os seguintes tipos primitivos int long e double Essas são as Primitive Specializations As Primitive Specializations foram adicionadas para remover a necessidade de se lidar com autoboxing e unboxing de tipos primitivos e assim melhorar a performance da aplicação Esses tipos não são parametrizados exceto as variantes Function lt T R gt que devem ser parametrizadas Por exemplo LongFunction lt int gt que recebe um long e retorna um int A interface Function lt T R gt tem nove variantes complementares que são utilizadas quando o tipo de retorno éprimitivo Jápara funções que recebem o mesmo tipo como argumento e retorno a interface UnaryOperator lt T gt entra na cena Para encontrar interfaces variantes complementares de Function lt T R gt para retornos que resultem em primitivos basta procurar interfaces onde o nome segue o padrão lt Src gt To lt Result gt Function por exemplo LongToIntFunction Háseis variantes para essa condição Agora para encontrar as interfaces variantes complementares de Function lt T R gt para parâmetros do tipo primitivo porém o retorno uma referência para um objeto basta procurar as interfaces onde o nome segue o padrão lt Src gt ToObjFunction por exemplo LongToObjFunction Hátrês variantes para esse tipo de interface Hátambém variações especiais para Predicate lt T gt Function lt T R gt e Consumer lt T gt onde ambas aceitam dois argumentos BiPredicate lt T U gt BiFunction lt T U gt e BiConsumer lt T U gt BiFunction lt T U gt também tem variantes que retornam os três tipos primitivos relevantes ToIntBiFunction lt T U gt ToLongBiFunction lt T U gt e ToDoubleBiFunction lt T U gt Jáa interface BiConsumer lt T U gt tem variações que recebem dois argumentos uma referência de objeto e um tipo primitivo ObjDoubleConsumer lt T gt ObjLongConsumer lt T gt e ObjIntConsumer lt T gt somando no total nove versões de dois argumentos das interfaces básicas Temos também a interface BooleanSupplier uma variante de Supplier lt T gt que retorna um boolean Resumo das seis interfaces funcionais básicasA maioria das interfaces funcionais padrões existe somente para fornecer suporte para os tipos primitivos então Não ceda àtentação de usar as interfaces funcionais básicas com os tipos primitivos ao invés de utilizar as interfaces funcionais primitivas jáexistentes na biblioteca padrão As consequências advindas da utilização do empacotamento dos tipos primitivos podem ser perigosíssimas para operações em massa Segue um resumo de cada uma das seis interfaces funcionais básicas Consumer lt T gt Essa interface representa uma operação que vai aceitar um input do tipo T e não retornaránada void método abstratoacceptdefault method s

interface representa um objeto fábrica que espera retornar dado objeto do tipo T método abstratogetdefault method s Uso comumUtilizado para criar Streams infinitos preguiçosos lazy do tipo T e também utilizado como parâmetro para o método orElseGet da classe OptionalPrimitive SpecializationsIntSupplier LongSupplier DoubleSupplier ️Voltar para a lista das interfaces funcionais mais utilizadas Predicate lt T gt Essa interface define um objeto de função muito utilizado para checar se o argumento do tipo T satisfaz ou não alguma condição returnando true ou false método abstratotestdefault

do mesmo tipo T Essa interface éuma especialização da interface Function lt T gt isto é ela estende a interface Function lt T gt método abstratoapplydefault method s andThen composeUso comumQuando

nome reduce da classe StreamPrimitive SpecializationsIntBinaryOperator LongBinaryOperator DoubleBinaryOperator ️Voltar para a lista das interfaces funcionais mais utilizadas Émuita informação para assimilar porém a maior parte das interfaces funcionais jáforam escritas e estão disponíveis na biblioteca padrão do Java e seus nomes foram estruturados para que não seja difícil encontrá las quando precisarmos delas Criando a sua interface funcionalCaso nenhuma dessas interfaces padrões mencionadas anteriomente satisfaça o que deseja fazer como por exemplo a necessidade de criar um predicado que suporte três argumentos ou a necessidade de ter uma interface funcional que lance exceções checadas veja aqui um artigo meu que fala um pouco desses tipos de exceções então a criação de uma interface funcional customizada seránecessária Outro fato também a se considerar éque terámomentos que devemos escrever nossa própria interface funcional mesmo quando alguma outra interface padrão éestruturamente idêntico Quando ela a sua possível interface funcional apresentar requisitos fortes na qual seu nome seja relevante para o domínio do negócio que ela se propõe a resolver talvez seja uma boa sua escrita Uma forma de ter certeza da necessidade de criar uma interface funcional sob medida seria quando ela assume uma ou mais das seguintes características Ela estáassociada a um contrato forte Ela seráusada com frequência e poderia se beneficiar de um nome descritivo Ela se beneficiaria de métodos padrões customizados Uma vez que decidimos em criar nossas próprias interfaces funcionais elas precisarão seguir alguns critérios para serem consideradas interfaces funcionais válidas Os critérios são Tem que ter apenas um método abstrato Pode ou não conter vários métodos estáticos Pode ou não conter vários métodos default Outro detalhe opcional porém muito útil éanotar essas interfaces com a anotação FuncionalInterface Além de deixar explícito o propósito para qual a interface foi criada também instrui o compilador a reforçar a checagem para verificar se a interface realmente se qualifica como uma interface funcional Interfaces funcionais a fundação para permitir a programação funcional com JavaAs interfaces funcionais são sem dúvida uma peça fundamental para que possamos utilizar o estilo funcional em nossos códigos Java Elas promovem o reuso de código e abrem a oportunidade de aplicarmos Higher order functions passando de lápara cáobjetos de função definidos por Lambda Expressions ou por Method References Esses detalhes tendem a auxiliar a criação de códigos concisos menos propenso àerros facilitando o entendimento manutenção e evolução E éisso galera Espero que tenha gostado do texto Se gostou e achou relevante esse conteúdo compartilhe com seus
