Q33 from jtips mock 1
I thought it should give compiler error,statement not reached but ans given is 18.
Please help
Given:

<font size=2> class Test { 
   public int x; 
   public static void main(String [] args) 
   { 
      Test t = new Test(); 
   } 
  
   Test() 
   { 
      System.out.println(" x = " + process()); 
      x += (x=18); 
      System.out.println("x = " + x) ; 
   } 
  
   int process() { 
      while(false) 
     { 
        return x=9; 
     } 
     return 10; 
   } 
 } 

What is the Output?
1.Prints 10
2.Prints 28
3.Compile-time error occurs.
4.Prints 18.
5.Prints 27

Answer is wrong. It gives a compile error. Try to compile the code and you'll see it. The only construct with which you can use false is with "if" so that you may insert debug conditional compilation.

If you use JBuilder, it'll compile (but the statement will hopefully be optimized away), but if you use SUN's own compiler (javac) you'll get the error.
Guess the author of the mock-exam uses JBuilder or something similar.
