Two switch Statement Examples

Below give two code samples of switch statement.

SwitchStmt.java (the switch statement) 
class SwitchStmt {
  public static void main( String args[ ] ) {
    int x = 10, y = 20, z = 30;
    switch ( 10+10 ) {
      case x:
        System.out.print( x );
        break;
      case y:
        System.out.print( y );
        break;
      case z:
        System.out.print( z );
        break;
      default:
        System.out.print( 40 );
        break;
    }
  }
}
Output:             Result:

Another example of the switch statement is given next:

BreakKeyword.java (the break keyword) 
class BreakKeyword {
  public static void main( String args[ ] ) {
    int x = 10, y = 20;
    switch ( x+y ) {
      case 20:
        System.out.print( x );
        break;
      case 30:
        System.out.print( y );
      case 40:
        System.out.print( x+y );
        break;
      default:
        System.out.print( 50 );
    }
  }
}
Output:             Result:
