java中的逻辑异或运算符是什么？

What is the logical xor operator in java?

提问by Pokechu22

In java, there is a logical OR operator (||) and a logical AND operator (&&). Is there a logical XORoperator? I tried ^^but it does not work.

在 Java 中，有一个逻辑 OR 运算符 ( ||) 和一个逻辑 AND 运算符 ( &&)。是否有逻辑异或运算符？我试过了，^^但它不起作用。

The logical XOR operator does exist in Java and is spelled ^.

Java 中确实存在逻辑 XOR 运算符，拼写为^。

To get the terminology right, in Java:

为了使术语正确，在 Java 中：

• &, |and ^are called bitwiseor logicaloperators, depending on the types of their arguments;
• &&and ||are called conditionaloperators.

• &,|和^被称为按位或逻辑运算符，这取决于它们的参数类型；
• &&和||被称为条件运算符。

For details, see JLS § 15.22. Bitwise and Logical Operatorsonwards.

有关详细信息，请参阅JLS § 15.22。位运算符和逻辑运算符。

There is no direct equivalent for &&and ||for XOR. The only reason &&and ||exist as separate operators from &and |is their short-circuiting behaviour(that's why they're called "conditional"), and XOR cannot be short-circuited.

没有直接的等价物&&，并||进行XOR。唯一的原因，&&并||作为独立的运营商存在的&，并|为他们的短路行为（这就是为什么他们是所谓的“条件”），和XOR不能短路。
