Java Convert integer to hex integer

Question

I\'m trying to convert a number from an integer into an another integer which, if printed in hex, would look the same as the original integer.

For example:

C

Answer 1

public static int convert(int n) {
  return Integer.valueOf(String.valueOf(n), 16);
}

public static void main(String[] args) {
  System.out.println(convert(20));  // 32
  System.out.println(convert(54));  // 84
}

That is, treat the original number as if it was in hexadecimal, and then convert to decimal.
