If you have zero coding experience you're going to need a really impressive resume.Ĭoding takes time regardless if you're doing it part time or doing it full time. Avoid lots of Util classesīe careful if you find yourself adding a lot of methods to a Util class.Think logically about this decision. Optionally, you can make the class itselfįinal so that it can't be extended and made mutable. Them up dynamically and then mark them immutable by calling the build method.Ĭlasses should be made immutable by declaring fields immutable (via final)Īnd by using immutable collections. These have builders so that you can build Of course, if theįooWidget itself isn't immutable you could easily mutate it.Ĭollections should, whenever possible, use the Guava Keyword works with if/else blocks and with try/catch blocks. Now you can be sure that fooWidget won't be accidentally reassigned. fooWidget is guaranteed to be set here If a value may or may not be present, wrap it in If you're using Java 8, you can use the excellent new If you're going to use null,Ĭonsider the annotation. Should have instead returned an empty collection. They don't use Spring's XMLĬonfiguration file format, and instead they put the injection logic in Good alternatives to using Spring is Google and Square's Dagger There should be absolutely no logic orĬontrol structures in XML. If you use the XMLĬonfiguration, it's important that you don't overuse Spring because It has aĮither code-based wiring or XML configuration-based wiring. In Java, this is typically done with the Spring Framework. Because Java strongly encourages OO design, to make testable software,

The best ways to write testable software is to use dependency injection This is more of a software engineering section than a Java section, but one of This has no effect on the compiler, but will inform your users via documentation One nifty trick is to put RuntimeExceptions in your method's throws declaration. Than forcing them to handle/declare that it throws every time, which pollutes ThisĪllows your users to handle your exceptions in the way they would like, rather Better is to make your exceptions extend RuntimeException instead. Theyįorce your users to add many try/catch blocks and wrap your exceptions in their

Some great code generation libraries are immutables, Google'sĬhecked exceptions should be used with caution, if at all. Seeįor an interesting discussion of some of the problems with normal Java coding This minimizesīoilerplate code, reduces probability of bugs and promotes immutability. Processor to generate them from interfaces automatically. If you create many immutable objects by hand, consider using the annotation Libraries which can help you generate builders. Instead of creating builder objects by hand, consider using one of the many We were trying to avoid, but it gets you immutable objects and a very fluent This ends up with a lot of the boilerplate There are better examples of Builders elsewhere but this should Traditional way to do this is to define a JavaBean:įinal ComplicatedDataHolder cdh = new ComplicatedDataHolder. One of the simplest things we as programmers do is pass around data.

The new style is much cleaner, more correct, and easier on the eyes. Traditionally, Java was programmed in a very verbose enterprise JavaBean style. Read this in other languages: English, 简体中文 Table Of Contents Would recommend taking the parts that speak to you and use them, rather than Practices, and tools to make using Java better. Since Java 8 came out recently, I decided to compile a list of libraries, Well, Java is actually an alright programming language, and Java is one of the most popular programming languages around, but no one seems Note: I'm working on version 2 of this guide and I need your help!
