Methods are similar to the functions that are used to perform various operations and represent behavior of an object. They are the lines of code that performs a specific function in a program. They can either return a value or not return anything. The main reason why methods are used in a program is because of it’s code reusability.

The java method is a piece of code that only executes when it is called. We can pass the data, called parameters, into a method. The methods are practised to do specific actions, and they are also called functions. This method also gives the simple modification and better readability of code by adding or removing a piece of code.
To reuse a piece of code: Specify the code once, and use it several times. Then, there is no need to write the code again and again.
The method needs to be declared within a class. It is specified with the name of the method, accompanied by parentheses (). The Java method gives some predefined methods, like System.out.println(); however, users can also generate their methods to do specific tasks.
To call a method in Java, you have to write the method's name accompanied by two parentheses () and one semicolon.
