In this quick tutorial, we'll learn about the Java XOR operator. We'll discuss a bit of theory about XORoperations, and then we'll see how to implement them in Java. Visualizza altro Let's begin with a reminder of the semantics of the XOR operation. The XOR logical operation, exclusive or, takes two boolean operands and returns true if, and only if, the … Visualizza altro Now let's see how to express the XOR operation in Java. Of course, we have the option to use the && and operators, but this can be a bit wordy,as we're going to see. Imagine a Car class having two boolean … Visualizza altro In this article, we learned about the Java XOR operator. We demonstrated how it offers a concise way to express XOR operations. As usual, the full code of the article can be found over on GitHub.
