Reducing the repetitive java code

Just came across this neat hack of reducing your boilerplate java code. The project lombok is one such micro framework that injects the commonly occurring code based on the passed annotations. It is not an annotation processor, but rather an IDE integration that adds code on the fly.
After downloading, run the jar and specify your eclipse installation. You then need to restart the eclipse for the changes to take place. One of the most used annotation is the @Data annotation that wraps various other annotations in itself.
In case of this annotation name creating conflicts, the user can opt for member specific annotations .

import lombok.Data;
public class Pojo{
    private String name;
    private int id;
    private float weight;
In this case, we only need to specify the member fields and all the getters/setters as well as commonly overridden methods like toString and hashCode would be auto-generated by the IDE.
There are provisions for other IDEs and command line execution also for non-eclipse users which make this a nifty tool to use.
