获取 Java 布尔值的倒数的最简洁方法是什么?

2022-01-19 00:00:00 boolean inverse java

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;
