海外TECH	DEV Community	Understanding Java packages for the absolute beginner.	https://dev.to/onychris/understanding-java-packages-for-the-absolute-beginner-5dik	Understanding Java packages for the absolute beginner What are Java packages We all began from somewhere in our journey to learning how to code and software development in general One characteristic of seasoned developers is not that they can write codes or their thought processes it is that their foundational knowledge is solid They know this stuff So any beginner Java programmer aspiring to be great should get an excellent grasp of the basics especially Java Packages When you see the term “package don t think of it as jargon to deceive you Instead think of folders and folder structures because thats what a package is in the most basic form Java packages are clusters of comparable varieties of categories interfaces and sub packages It is a mechanism for encapsulating teams of Java packages classes sub packages and interfaces Types of Java packagesThere are essentially two types of Java packages namely the User defined packages and the built in packages Built in packageThe built in package consists of the many categories that constitute a part of the Java API A number of the inherent packages are java lang Contains language support categories for example categories that outline default knowledge varieties like math java io Contains categories to support input output operations java util Contains utility categories for implementing knowledge structures like a List of collections and dictionaries to support date time work java applet Contains categories for making applications programms java awt Contains categories for implementing elements of graphical user interfaces for example buttons menus etc java net Contains categories that support network operations User defined packagesAs the name suggests these packages are user defined We create a folder whose name should be the same as the name of the package Next we create a class inside the folder Package names and directory structure are closely related For example if a package name is school faculty department then there are three directories school faculty and department The school package can be thought of as a tier one package while faculty is a school sub package and department is a sub package of faculty Why do we need packages in Java Java packages make it easy to find or locate classes and interfaces Java packages help to avoid name conflicts For example there could be two classes with the name Student in two packages school scienceDepartment Student and school educationDepartment Student Java packages perform data encapsulation or data masking Java packages provide controlled access Access designations are protected and have packet level access control by default A member declared as guard is accessible by classes of the same package and its subclasses A member without an access specifier is a default identifier that can only be accessed by classes in the same package Java packages reuse classes contained in packages from other programs Java packages provide a unique comparison of classes in other packages	2021-09-06 14:36:47
海外TECH	DEV Community	Writing "The Art Of Micro Frontends"	https://dev.to/florianrappl/writing-the-art-of-micro-frontends-31ce	Writing quot The Art Of Micro Frontends quot Two months ago my book The Art of Micro Frontends was published by Packt Personally I had a great time writing the book and working together with the amazing people at Packt which is why I wanted to share the experience and give a little bit of advice from my point of view Florian Rappl florianrappl So happy that my book art of microfrontends has finally been published packt live wkfkX Thanks to the whole team at PacktPub and everyone contributing PM Jul In short this is how the book looks like on Amazon The IdeaThe idea of writing a book about micro frontends was born in mid when Piral was born out of smapiot s open source efforts We ve been leading and assisting to micro frontend implementations for a while and our intention was to put together an almost ideal pattern into an open source framework Even though our framework is primarily targeted at client side rendering our knowledge in the whole space is something that is worth talking about Over the years I was fortunate enough to give talks at numerous conferences and publish dozens of articles on the subject One of the bigger conference where smapiot as a company was asked to present was O Reilly s Software Architecture conference in Berlin Here we got in touch with some of the people at O Reilly discussing various opportunities Ultimately it became clear that packaging my knowledge into a book may be a task worth doing Finding a PublisherFirst approached by O Reilly but that was no fit as the expectation already deviated from my vision Also I heard that Luca may already be in touch with them so I was not positive that any proposal would make it through their processes Why should they publish two books on the same subject I was then approached by Manning but since they already got a great book by Michael Geers they have only been interested in something like an online lecture called live project Here their idea was to come up with some real life scenario that needs to be implemented by the student I was actually already convinced that this may be a viable way forward however the response to the proposal was then frustrating Keeping all their requirements in mind they then pretty much went into the opposite direction For me this was a deal breaker as I value consistency and don t like my time being wasted The third party to approach me was Packt Here everything went right from the beginning It was clear that they are highly interested in publishing a book and that they want it to be published by me and the way I envision it Once settled that we are on the same page they requested a detailed outline My advice on this one is to go with a publisher who you believe understands you and the thing you want to write about If you are not convinced of their intentions or plans for the book then don t do it Most likely your book will not make you rich That s fine But you should be fine with the book and its contents The book should provide you something you are happy to talk about use as a reference and show around Don t necessarily go with the best offer regarding money Go with the offer that reflects your idea the best The TimeI ve started writing the book in November and finished around May All in all I d not recommend spending less time on it Especially if you want to fine tune some graphics you ll need more not less time for writing a book with pages the book has even around pages making it even more time consuming to write Outlining the ContentOne of the hardest parts about writing a book is finding the correct structure In the end this will determine quite a few things and will actually make the book more accessible to some readers than to others I did not want to do experiments here So I ve chosen a structure that starts with some general ideas and motivations before it covers the available patterns in the most practical way Finally after the practical part ends I ve chosen to include some case studies and high level information which may be useful to successfully implement micro frontend projects at larger companies What surprised my from the publisher was that the process of outlining the book was really detailed It turns out that this is a lot of work It was not only about finding the right structure but also explaining it writing what is actually covered in quite some detail and then even estimating the amount of pages Especially the last part is tricky How should I estimate the amount of pages if I don t know what examples I ll use or how much space they require What format is used here I had to make some assumptions here like A with font size pt will be used here for these drafts I also assumed that things like diagrams and code will take about of the space meaning that every word only estimate would need a fixed factor of to be more realistic My advice on this would be Take your time here This may be the most important work and it will happen before the actual work which may be deceiving Everything you do here will not only follow you for the rest of writing the book but also for the book itself There may be future editions of the book but they will rarely i e never deviate from the plan you make here Make it good Think about it twice and then one more time One of the things that bothered me in the whole context was that basic things like terminology have not been determined yet I was already writing a lot of text assuming a standard vocabulary One of the most basic things was how to refer to micro frontends Micro Frontends and AlternativesIf you start a Google search you ll see some variants on the matter microfrontends micro frontends and micro frontends Personally I am a strong believer in microfrontends If you write microservice you also need to settle on microfrontend There is no other way However if you are a strong believer in the first one to mention it wins philosophy then potentially micro frontend is the one this is the name that was chosen by ThoughtWorks when it appeared on their tech radar Naturally there was an initial discussion about what word to use here While some favored micro frontends or micro frontends mostly due to SEO I was quite convinced that consistency is key therefore opting into microfrontends This was then also the chosen name until well pretty much the last draft Then it was changed in a mutual agreement due to better alignment with the community and better search results on Amazon Today I still stay strong on my desire regarding consistency here but I also feel that MF is a good acronym In the end it does not matter much as long as everyone knows what s behind that word A much easier discussion was around the title Choosing the TitleThe title of the book should somewhat not only reflect its contents but also its ambition It should draw the attention of potential readers And it should be minimal and to the point This is not an easy thing to achieve It may actually be one of the hardest parts in writing Together with some editors at Packt we brainstormed this a bit and came up with some suggestions In the end we settled for a quite conservative yet bold statement The Art of Micro Frontends essentially tries to be a complete reference for the subject while staying practical and down to earth My advice on this would be go with a title you are comfortable with and that would make you happy to have on a book That the title should at least up to a certain degree reflect the contents of the book should be self explanatory here Don t lie but still try to sell it and make you happy ConclusionOverall I had a great experience writing the book The feedback and suggestions from the Packt team has been great They are always very welcoming and try to make the best possible product here The only regret that I have is that I did not insist on reviewing the last draft in more detail I d have wished to still get on or the other smaller fix or improvement in there but luckily these are only minor exceptions and overall I am pretty happy with the outcome	2021-09-06 14:07:12
