public class Test9 {
              static boolean foo(char c) {
                System.out.print(c);
                return true;
              }
              public static void main( String[] argv ) {
                int i =0;
                for ( foo('B'); foo('A')&&(i<2); foo('C')){
                                i++ ;
                                foo('D');
                  }
