The return Statement

The return statement is used to explicitly return from a method. That is to say that it causes a program control to transfer back to the caller of the method.
ReturnDemo.java (the return statement)

print?
01// Java program to illustrate using return
02class ReturnDemo {
03  public static void main( String args[ ] ) {
04    boolean bool = Boolean.parseBoolean( args[0] );
05    ReturnDemo myObj = new ReturnDemo( );
06    if ( bool ) {
07      System.out.print( myObj.myMethod( 10 ) );
08      return;
09    }
10    System.out.print( 20 );
11  }

13  int myMethod( int n ) {
14    return( n + 5 );
15  }

If a method is without any return values, use the void keyword to specify that a method should not have a return value:
VoidDemo.java (the void keyword)

print?
01// Java program to illustrate using void keyword
02public class VoidDemo {
03  public static void main( String args[ ] ) {
04    myMethod( args[0] );

07  static void myMethod( String a ) {
08    System.out.print( a );
09    return( );
