In this article, we will learn about this keyword in java, how and where to use them with the help of examples. in java, this keyword is used to refer to the current object inside a method or a constructor. This keyword is a very important keyword to identify an object. following are the usage of this keyword. following example shows a simple usecase of this keyword. compile and run the above program.
