/* DemoChar */
package eg;
public class DemoChar
{
  public static void main( String [] args )
  {
    System.out.println( "Character.MAX_VALUE + 1 = "
            + (Character.MAX_VALUE + 1) );

    char foo1, foo2;
    foo1 = (char) (Character.MAX_VALUE - 1);
    foo2 = (char) (foo1 / 2);
    System.out.println( "foo1 = "+ (int) foo1 +", foo2 = "+ (int)
foo2 );

    foo1 = '§';
    foo2 = '@';
    char sum = (char) (foo1 + foo2);
    System.out.println( "foo1 + foo2 = "+ sum );
  }
