  • 第5题：

    假设变量sum=0和j=80都是int类型，则下列语句中的正确的是( ).

    A．if (true) System. out. println("true"); else;

    B．if (5＜＞1) System. out. println( "not equal" );

    C．for (iht j=20;j＜＜50;j--) System. out. println (j);

    D．while (j＞＞=50) sum +=j; j--;


    正确答案：A
    解析：选项B中，不等于关系运算符不是＞，而是!=；选项C中，for循环里第二个语句 j20的结果不是布尔型；选项D中，条件表达式的结果也不是布尔型，而且循环体应该包括两条语句，这时需要加{}将j--；也包含在循环体内。
