Java stubs exercise

Define stubs for the methods called by the below main(). Each stub should print "FIXME: Finish methodName()" followed by a newline, and should return -1. Example output:

FIXME: Finish getUserNum()

FIXME: Finish getUserNum()

FIXME: Finish computeAvg()

Avg: -1

I am unsure of what this is asking me to do and how to complete it. It is for my CS200 class. Can anyone give me some tips/the solution?

The code I was provided:

public class MthdStubsStatistics {

   /* Your solution goes here  */

   public static void main(String [] args) {
      int userNum1;
      int userNum2;
      int avgResult;

      userNum1 = getUserNum();
      userNum2 = getUserNum();

      avgResult = computeAvg(userNum1, userNum2);

      System.out.println("Avg: " + avgResult);
   }
}
