In this third part of Java puzzlers, we will see a surprise in variable naming restrictions.

If I show you this, I’m sure you won’t be surprised that this does not compile. static is one of the reserved keywords so why should it work?

public class Puzzler {

 public static void main(String[] args){

 int static = 2;
 }

}

Now I’ll ask you a more difficult one. What you think about the below code. Will this compile?

public class Puzzler {

 public static void main(String[] args){
 int bool = 0;
 int integer = 1;
 int const = 2;
 int goto = 3;
 }
}

None of these should be reserved keyword. This is not C right? If you thought that it will compile, you’re wrong. const and goto are reserved keywords, but bool and integer are fine.
