什么是XOR和不等于-TO的区别？ [英] What's the difference between XOR and NOT-EQUAL-TO?

问题描述

我的问题使用Java作为一个例子，但我想它适用于所有可能

My question uses Java as an example, but I guess it applies to probably all.

有没有和XOR运算符（^在Java）之间的实际差异不等于-TO（！=在Java），比较布尔值当？

Is there any practical difference between the XOR operator ( ^ in java) and the NOT-EQUAL-TO ( != in java), when comparing booleans?

我在这里评价的东西，但我一直在想（似乎不可思议，两件事情相等）......并没有在网络上找到任何东西。在一些论坛上很快结束，没有任何结果只是一个讨论。

I evaluated things here, but I just kept wondering (seems weird, two things equal)... and didn't find anything on the net. Just one discussion in some forum that ended quickly without any result.

推荐答案

有关布尔值，它们指的是同样的事情 - 虽然有一个复合赋值操作符的XOR：

For Boolean values, they mean the same thing - although there's a compound assignment operator for XOR:

x ^= y;

有对不平等没有等价复合赋值操作符。

There's no equivalent compound assignment operator for inequality.

至于为什么他们都可以 - 这将是奇怪的XOR的不的可用只是因为它的工作方式是相同的不平等。它理应在那里，所以它是。对于非布尔类型的结果是不同的，因为它是一个不同的结果类型，但是这并不意味着它是有意义的去除异或布尔。

As for why they're both available - it would be odd for XOR not to be available just because it works the same way as inequality. It should logically be there, so it is. For non-Boolean types the result is different because it's a different result type, but that doesn't mean it would make sense to remove XOR for boolean.
