Infinite Loop Question - should be simple

Question

Ok I think I have a simple question to ask here. I am attempting to create a program that creates an infinite loop for multiples of two...
ex: 2, 4, 8, 16, etc...
The math behind it is simple, x^2 when x = 2. I then want the result of each equation to be squared, and infinitely.
Here is the code Ive written so far, I think Im close, but I may be way off... any hints or clues as to my next step would be appreciated.
public class loopytest {
   public static void main (String[] args)
   int x = x^2;
   while (x = 2)
   System.out.println("Value of x is " + x);
}

Answer 1

int x = x^2;You have to initialise "x" first.
You should give it an actual value (e.g. 2) for this case.
int x = 2;If you want to get the value of x from arguments. (e.g. java YouProgram 2)
You should change this part of code similar to the follow.
int x = args[1];But this one hasn't used the Math.pow(), you should read the API and amend it.
while (x = 2)This one is actually assign x with value 2.
If you want to compare an int, you should use "A == B", "A.equals(B)" for Object.
