东方神起去哪了
问题描述
如果你有一个布尔变量:
If you have a boolean variable:
boolean myBool = true;
我可以通过 if/else 子句得到相反的结果:
I could get the inverse of this with an if/else clause:
if (myBool == true) myBool = false; else myBool = true;
有没有更简洁的方法来做到这一点?
Is there a more concise way to do this?
推荐答案
只需使用逻辑非运算符 ! 进行赋值，就像您在条件语句(if, for, while...).您已经在使用布尔值，因此它会将 true 翻转为 false(反之亦然):
Just assign using the logical NOT operator ! like you tend to do in your condition statements (if, for, while...). You're working with a boolean value already, so it'll flip true to false (and vice versa):
myBool = !myBool;
