Lombok features

@Getter / @Setter: Never write public int getFoo() {return foo;} again.
@ToString: No need to start a debugger to see your fields: Just let lombok generate a toString for you!
@EqualsAndHashCode: Equality made easy: Generates hashCode and equals implementations from the fields of your object.
@Data: All together now: A shortcut for @ToString, @EqualsAndHashCode, @Getter on all fields, and @Setter on all non-final fields. You even get a free constructor to initialize your final fields!
@Cleanup: Automatic resource management: Call your close() methods safely with no hassle.
@Synchronized: synchronized done right: Don't expose your locks.
@SneakyThrows: To boldly throw checked exceptions where no one has thrown them before!

The documentation above is a lot easier to follow, but if you want to build your own transformations, or you want to add javadoc to lombok.jar in your IDE, you can also check out the javadoc.
