How can a Java variable be different from itself?

Question

I am wondering if this question can be solved in Java (I\'m new to the language). This is the code:

class Condition {
    // you can change in the main
    p         


        

Answer 1

int x = 0;
if (x == x) {
    System.out.println("Not ok");
} else {
    System.out.println("Ok");
}
