The keyword "this" refers to the current class instance.
this.getName(); is used to call the getName() method of the current class. Ideally speaking just getName(); should be sufficient but still using the this keyword is a good practice.
You will find its use in case of inheritance and method overriding where you would have methods of the same name in both the current class and its parent. In such situations how can you specify which method to call?
You use the "this" keyword for the current class and the "super" keyword for the parent class.
Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. It's also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing.
