Methods in JAVA

Methods:
       
 Functions in C++ are called as methods in JAVA.Methods  do have some specifications.There are three parts of methods.They are

• Method declaration
• Method definition
• Method calling/Invoking

Method declaration is not possible.Programmer can directly define and call their method.There are some built-in methods available as in other programming languages.

Sample JAVA program using methods:

Class Myclass

{

          public void hello()

          {

                 System.out.println("First program with a method");

          }

}

Class Mainclass

{

          public static void main(String[] args)

          {

                Myclass c=new Myclass();

                c.hello();     

          }

}

In this program,there are two classes.when you save your program you should save with name of class in which the main function is residing.

Static Functions:

            It is possible to create a static functions in JAVA.Static functions are those functios  which can be called without using objects.

Example of a static functions:

Class Myclass

{

          public void hello()

          {

                 System.out.println("First program with a  static method");

          }

          public static void main(String[] args)

          {

                hello();     

          }

}
