Using Primitive Arrays

    // of the new statement can only be done if declaration
    // and assignment take place within one statement

    // java provides a special property on arrays
    // NOTE: length is not a method, hence no parenthesis

    // accessing arrays
    for( int i = 0; i < bags.length; i++ ) {
      System.out.println( bags[i] );
