In Java XOR with three true inputs returns true. Why?

Question

The following code

System.out.println(\"1 0 0: \" + (true ^ false ^ false));
System.out.println(\"1 0 1: \" + (true ^ false ^ true));
System.out.println(\"1 1 0:         


        

Answer 1

Think about how the compiler evaluates this:

(true ^ true) ^ true

After first term true ^ true, which is false, has been evaluated:

(false) ^ true ==> true
