System.out.println(mumu.name+"what are u doing at 9 oclock?");
System.out.println(mumu.getState(9));
System.out.println("what about 23?");
System.out.println(mumu.getState(23));
}
}
请问为什么调用不了时间？得出来的结果是这个？
mumuwhat are u doing at 9 oclock?
the wrong time
what about 23?
the wrong time

神马玩意？
没见到哪儿打印 the wrong time 的。。。
------解决方案--------------------
state为啥没赋值？？？？
------解决方案--------------------
运行没什么毛病呀，很正常呢

真不知道你的the wrong time哪来的。。
