Integer to Hex conversions.

[Sharda Vajjhala]

This is a question from Dan's Fundamentals exam:
class B {
public static void main(String args[]) {
System.out.print(Integer.toHexString(Integer.MIN_VALUE)+",");
System.out.print(Integer.toHexString(Integer.MAX_VALUE));
}
}
This prints out
80000000,7fffffff
How?? I don't understand this. I understand the MAX_VALUE conversion, but not the MIN_VALUE.
