The return value can be a constant, a variable, or an expression. The only requirement is that the return value be of the type specified in the method definition.

//Demo Program for Methods

import java.io.*;

import BreezyGUI.*;

public class method1test

{

     public static void main(String[ ] args)

    {

          greeting(5);  //first method call

          int response;

          response = getNumber();   //second method call

          greeting (response);          //first method call again

    }

 
     //First Method for greeting

     public static void greeting(int x)

    {

         int i;

         for(i = 0; i < x; i++)

         {

               System.out.print("Hi ");

         }

         System.out.println( );

    }
    //Second method which returns a number

    public static int getNumber( )

    {

         int number;

        do

        {

            number = Console.readInt("\nPlease enter value(1-10): ");

         }

        while ((number < 1) || (number > 10));  //error trap

        return number;  //return the number to main

    }

}

Output:
Hi Hi Hi Hi Hi

Please enter value(1-10): 5
Hi Hi Hi Hi Hi

takes arguments AND returns a value.

//Demo Program for Methods

public class method1test

{

     public static void main(String[ ] args)

     {

          int test1 = 12, test2 = 10;

          // notice in this next line the method called min

         System.out.println("The minimum of " + test1 + " and " + test2

                                                       + " is " + min(test1,test2) + ".");

     }
     //Method to find minimum

     // This method needs to receive two integers and returns one integer.

     public static int min(int x, int y)

     {

          int minimum;  // local variable

          if (x < y)

                minimum = x;

          else

                minimum = y;

          return (minimum);  // return value to main

     }

}

The minimum of 12 and 10 is 10.
