创建“逻辑排他性”或“ Java中的运算符 [英] Creating a "logical exclusive or" operator in Java

问题描述

Java有一个逻辑AND运算符。

Java有一个逻辑OR运算符。

Java有逻辑NOT运算符。

Java has a logical AND operator.
Java has a logical OR operator.
Java has a logical NOT operator.

Java没有逻辑XOR运算符，根据sun 。我想定义一个。

Java has no logical XOR operator, according to sun. I would like to define one.

作为一种方法，它只是定义如下：

As a method it is simply defined as follows:

public static boolean logicalXOR(boolean x, boolean y) {
    return ( ( x || y ) && ! ( x && y ) );
}

此方法按以下方式调用：

This method is called in the following way:

boolean myVal = logicalXOR(x, y);

我更愿意拥有一个运营商，使用如下：

I would much rather have an operator, used as follows:

boolean myVal = x ^^ y;

我找不到任何关于如何在Java中定义新运算符的内容。我应该从哪里开始？

I can't find anything on how to go about defining a new operator in Java. Where should I start?

推荐答案

Java 确实有一个逻辑XOR运算符，它是 ^ （如 a ^ b ）。

Java does have a logical XOR operator, it is ^ (as in a ^ b).

除此之外，您无法在Java中定义新运算符。

Apart from that, you can't define new operators in Java.

编辑：以下是一个例子：

public static void main(String[] args) {
    boolean[] all = { false, true };
    for (boolean a : all) {
        for (boolean b: all) {
            boolean c = a ^ b;
            System.out.println(a + " ^ " + b + " = " + c);
        }
    }
}

输出：

false ^ false = false
false ^ true = true
true ^ false = true
true ^ true = false
