+ Imagine you have a very simple class: +

public class Mountain { + private final String name; + private final double latitude, longitude; + private String country; +}

+ While that is fairly clear, that class is not complete. In fact, it won't compile like that.
+ You'll need to add a constructor to initialize those final fields, you probably want getters, a setter for country, + and to be complete, a nice toString as well as an implementation for equals and hashCode. + Eclipse can generate all these methods for you, but then you end up with over 70 lines of boilerplate. It's going to be hard + to see any surprises buried amongst all those lines of code! Lombok has the answer to this problem. +

+ So instead of this mess: +

+ lombok simply offers you an annotation that tells eclipse to generate all this stuff for us silently, without + cluttering up your source file, like so: +

+ Note how we haven't even saved the file yet, but in the outline view you can already see all the various methods generated + by the @Data annotation. That's because lombok is completely integrated into eclipse. The moment you type + the last character of your annotation, all the methods exist, just as if you write the last character on a method declaration. + In other words, lombok is not just an annotation processor! +

+ But what about your build process? Lombok works just as well in javac. All you need to do is add + lombok.jar to the class path as you compile. Like so: +

+ @Data is nice, but its certainly not the only boilerplate buster that lombok has to offer. If you need + more fine grained control, there's @Getter and @Setter, and to help you in correctly + cleaning up your resources, @Cleanup can automatically and without cluttering your source files generate + try/finally blocks to safely call close() on your resource objects. That's not all, but for the complete + list you'll need to head over to the feature overview. +

+ Ready to install lombok? Start by clicking the download button at the top of this page. Going from clicking that button + to having your eclipse ready to go takes less than 12 seconds - it's that simple. +

+ Thanks for checking out Project Lombok, and let us know what you think! +

+ I changed my mind - I do want to see the video! +
