My First Project and a Dive Into Dark Mode |
https://dev.to/trevortx/first-project-worldwide-weather-4dno
|
My First Project and a Dive Into Dark ModeHello world My name is Trevor and I m a software engineering student at Flatiron School I just wrapped up my very first project called Worldwide Weather and I m pretty excited about how the project turned out For this project our requirements were to use HTML CSS and JavaScript to create a front end single page app that also utilizes an external API Additionally we needed to incorporate at least three different types of event listeners and allow for some level of interactivity I decided to build a weather app because I find myself regularly having to search for the forecast since I go outside daily if only to take my dog for a walk I live in San Francisco and while people say the weather here is the same year round I find that it s highly dependent on how fast the wind is blowing and from which direction it s blowing from This makes knowing the forecast a requirement before leaving the apartment to venture into the world I also really like to travel and learn about new places So in order to combine the two I wanted to utilize a second API to pull a Wikipedia summary of the location the user searched and add it to the page in addition to the forecast To further take advantage of this I added a random button that pulls from a list of over cities so that the user can learn about a new city or potentially use the app to suggest a random destination for their next vacation if they re feeling adventurous One of the features I d like to discuss in depth is the dark mode that I created for the app Super quick background on that I love dark mode everything If it s an option I will always select dark mode On my laptop on my phone every time Back to the app I wanted to use one of my required event listeners on a dark mode button Specifically since I used Bootstrap I added a switch at the top of my page that s really just a checkbox but looks much more slick I had many elements on the page change when this switch was toggled but for simplicity s sake I ll highlight just one of them to demonstrate how I utilized the switch First thing s first since I m using Boostrap here s what the HTML looked like for the switch itself lt input class form check input type checkbox role switch id flexSwitchCheckDefault gt lt label class form check label for flexSwitchCheckDefault gt Dark Mode lt label gt In the screenshot below you ll notice that I have a Random location button Let s use that as our example In HTML here is what that button looks like lt button id random btn type button class btn btn dark gt Random location lt button gt Note that the class above btn btn dark is what s making the default button appear as black when the page is first loaded Within my JavaScript I need to do a few things next Create variables for both the Dark Mode switch and the random buttonAdd an event listener to the Dark Mode switch so that when the switch is changed it will toggle the Random button s class in accordance with Bootstrap to make it appear darkEnsure the functionality above works both ways as in it will also go back to light mode from dark mode when the button is toggled a second time So I created the variable to store the value of the Dark Mode switch const darkSwitch document getElementById flexSwitchCheckDefault Then I did the same for the Random button const randomBtn document getElementById random btn There are main components to the event listener I added Here s the code and then I ll break it down darkSwitch addEventListener change gt if darkSwitch checked remove and set attributes for dark mode randomBtn removeAttribute class randomBtn setAttribute class btn btn light else set attributes back to light mode randomBtn setAttribute class btn btn dark The first thing I did was add an event listener to the Dark Mode switch so that it detects a change event A change event will run a function whenever the element is changed from its current state in this case when the switch is toggled by the user One of the other things I needed to do was to ensure that the button changes back to light mode when toggled a second time Within my function I ll address that with an if statement The function begins with the if statement First it s checking to see if the switch has been toggled to Dark Mode in this case if it s checked since my switch is actually a checkbox that s appearing as a switch If it has I m actually removing any classes associated to the randomBtn before setting a new class which will control the color of the button effectively changing it from the dark button you see when the page loads to a white button to contrast the now darkened page Note that in this case I probably don t need to remove the attribute but it was added because other similar elements were giving me trouble If the switch is not checked we ll set the randomBtn back to the dark switch that you saw when the page first loaded Extrapolate that process to the other elements of the page and you get a functional dark mode See the gif below to see dark mode in action or feel free to visit Worldwide Weather s GitHub page and download the app and play around with it yourself Since this app was small it wasn t too much trouble to build a functioning dark mode by myself However there are alternatives Tailwind CSS for example has a dark mode built in Since I decided to use Bootstrap for this project I needed to build it myself since there s not night mode included in Bootstrap So depending on your needs and the size of your app you have options on whether dark mode is something you want to tackle by yourself or if you d prefer to use another framework that has a built in dark mode option I hope you enjoyed reading about this project and dark mode in particular Don t hesitate to reach out to me if you have any questions and thanks so much for reading Trevor |

O método toString do JavaCriou uma classe maneira e na hora de mostrar o resultado com print viu uns números estranhos class User private String name private int age User String name int age this name name this age age public class Main public static void main String args User user new User João System out println user Apenas um ex User abc Não se preocupe a sua classe estáapenas usando o método toString implementado na classe Object Nesta implementação éusado o nome da classe seguindo pelo símbolo e finalizando com o hashcode do objeto mas em hexadecimal Dápara atestar isso com o código abaixo class User private String name private int age User String name int age this name name this age age public class Main public static void main String args User user new User João String className user getClass getName int hashCode user hashCode String myToString className Integer toHexString hashCode System out println user toString equals myToString true Ou olhando a documentação Ou olhando o código fonte Porém somos livres para sobrescrever este método e deixar do jeito que quisermos class User private String name private int age User String name int age this name name this age age Override public String toString return User name name age age O jeito mostrado no exemplo acima éparecido com o que algumas IDEs geram automaticamente Mas na minha opinião háformas mais elegantes de obter o mesmo resultado veja Overridepublic String toString return String format User name s age d name age Ou com Java ou mais recente Overridepublic String toString return User name s age d formatted name age O que achou Não ficou muito mais fácil de ler Arrays também usam a implementação padrão e uma das opções mais simples que temos para mostrar o seu conteúdo écom o método Arrays toString veja import java util Arrays public class Main public static void main String args int numbers System out println Arrays toString numbers Se for uma array de arrays toString não éo bastante Precisamos do deepToString import java util Arrays public class Main public static void main String args int numbers System out println Arrays deepToString numbers Agora estamos prontos para deixarmos os nossos objetos mais apresentáveis |

How to use Function Pointers in Java ️ ✨ |
https://dev.to/gregorygaines/how-to-use-function-pointers-in-java-3f33
|
How to use Function Pointers in Java ️ IntroductionPointers are objects that store a memory address and can save memory by directly pointing to a target object array or variable address instead of passing by value Sadly Java doesn t have a real concept of pointers Lucky for us there s a workaround using method references that comes close to the real thing Function PointersA function pointer is a pointer that points to the address of a function Some uses are creating a callback routine by creating a function that calls another function based on its execution or storing an array of function pointers for dynamically calling methods Ex Storing CPU instructions for an emulator Simulating a Function PointerThere are four kinds of method references and we are using the kind that refers to an instance method of a particular object Start by defining an interface that defines the method signatures of the method s you are pointing to Wrapping interfaceprivate interface FunctionPointer Method signatures of pointed method void methodSignature int a Next create methods with the target method signature public void method int b System out println Called method with integer b public void method int v System out println Called method with integer v public void method int a System out println Called method with integer a The next step is to create variables of the wrapping interface and assign methods to them The variables will act as a function pointer to be stored or executed Create a variable of the interface and assign the method referencesFunctionPointer pointer this method FunctionPointer pointer this method Call both methods using their pointer pointer methodSignature pointer methodSignature Reassign and call pointer pointer this method pointer methodSignature Called method with integer Called method with integer Called method with integer Using LambdasMethod references can be assigned using lambdas Create a method reference and assign a methods using a lambda FunctionPointer pointer a gt System out println Called pointer with int a FunctionPointer pointer b gt System out println Called pointer with int b Array of Function PointersThe functionality of an array of method references can be emulated by creating an array of the wrapping interface Create an array of pointers FunctionPointer functionPointersArray new FunctionPointer Assign methodsfunctionPointersArray this method functionPointersArray this method functionPointersArray this method Call methods functionPointersArray methodSignature functionPointersArray methodSignature functionPointersArray methodSignature Function Pointer vs Direct CallYou may be wondering is there any penalty for using a method reference over directly calling a method The answer is yes but a tiny one From the chart above a direct method call is almost x faster than using a method reference because of the extra step to call the lambda than the stored method Honestly you probably won t notice the performance penalty so don t worry about it ConclusionPointers are variables that point directly to the address of objects instead of passing by value A function pointer directly points to the address of a function which can decrease memory consumption Java doesn t have pointers but can emulate the behavior using method references or lambdas Using a method reference is slower than a direct method call but not enough to deter usage of the feature Consider signing up for my newsletter or supporting me if this was helpful Thanks for reading |
