Wrong boolean expression in JDK 1.2, 1.1 different than >= 1.3 #7

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
DecTestBooleanOperators
        System.out.println((a && b && c) ^ 1);

In jdk 1.1:
public abstract class DecTestBooleanOperators {
    public static void test(boolean a, boolean b, boolean c) {
        System.out.println(" !&&");
        System.out.println(!a && b && c);
        System.out.println(!(a && b) && c);
        System.out.println(!a || !b || !c);
        System.out.println(" !||");
        System.out.println(!a || b || c);
        System.out.println(!a && !b || c);
        System.out.println(!a && !b && !c);
    }
}

1.2:
public abstract class DecTestBooleanOperators {
    public static void test(boolean a, boolean b, boolean c) {
        System.out.println(" !&&");
        System.out.println(!a && b && c);
        System.out.println(!(a && b) && c);
        System.out.println((a && b && c) ^ 1);
        System.out.println(" !||");
        System.out.println(!a || b || c);
        System.out.println(!a && !b || c);
        System.out.println((a || b || c) ^ 1);
    }
}

>= 1.3:
public abstract class DecTestBooleanOperators {
    public static void test(boolean a, boolean b, boolean c) {
        System.out.println(" !&&");
        System.out.println(!(a || !b || !c));
        System.out.println(!(a && b || !c));
        System.out.println(!(a && b && c));
        System.out.println(" !||");
        System.out.println(!(a && !b && !c));
        System.out.println(!(!(!a && !b) && !c));
        System.out.println(!(a || b || c));
    }
}
