        System.out.println(Boolean.valueOf("true"));
        System.out.println(Boolean.valueOf("True"));
        System.out.println(Boolean.valueOf("TRUE"));
        System.out.println(Boolean.valueOf("1"));
        
        System.out.println(Boolean.valueOf("false"));
        System.out.println(Boolean.valueOf("False"));
