Java this Keyword

Java Keywords : Using this with a class attribute (x)

Definition and Usage

The this keyword refers to the current object in a method or constructor.

The most common use of the this keyword is to eliminate the confusion between class attributes and parameters with the same name (because a class attribute is shadowed by a method or constructor parameter). If you omit the keyword in the example above, the output would be "0" instead of "5".

this can also be used to:
  • Invoke current class constructor
  • Invoke current class method
  • Return the current class object
  • Pass an argument in the method call
  • Pass an argument in the constructor call
