Missing main?

Question

I get an error when I run this program that says "missing method body or declare abstract", and the arrow points to the m in main. I can't seem to figure out what the problem is. I've tried switching the order of the main and the method, and that didn't help (just though I'd try it; I had no idea what to do).
import java.io.*;
import java.lang.Math;
import java.text.DecimalFormat;
class Powers {
public static void main(String[] args)
    throws IOException;
  BufferedReader inKeyBoard;
  inKeyBoard = new BufferedReader(new InputStreamReader(System.in));
  DecimalFormat fmt = new DecimalFormat("0.##");
  int base, exp;
  do{
   System.out.print("Enter the base: (or 0 to exit) ");
   base = Integer.valueOf(inKeyBoard.readLine()).intValue();
   System.out.print("Enter the exponent: ");
   exp = Integer.valueOf(inKeyBoard.readLine()).intValue();
   System.out.println("Built-in funtion: " + fmt.format(Math.pow(base, exp)));
   System.out.println("MyPow: " + fmt.format(MyPow(base, exp)));
   while(base != 0);
  static double MyPow(double base, int exp){
    double answer;
    answer = Math.exp(exp * Math.log(base));
    return(answer );
}

Do you take the error when you run or when you compile? Frankly, I'm not sure that this class will compile as it is. Check the extraneous semi-colon at the end of
public static void main(String[] args) throws IOException;
This throws the compiler off and makes it think it is an abstract method.
