How do i define stubs for the methods called by the below main()?

Question

Offer me the best recommendation on how to define stubs for the methods called by the below main(). The following command is used:

FIXME: Finish getUserNum()
 
 FIXME: Finish getUserNum()
 
 FIXME: Finish computeAvg()
 
 Avg: -1

import java.util.Scanner;
 
 public class MthdStubsStatistics {
 
  public static int methodName (int userNum1, int userNum2, int computerAvg) {
  System.out.println("FIXME: Finish getUserNum()");
  System.out.println("FIXME: Finish getUserNum()");
  System.out.println("FIXME: Finish computerAvg()");
  System.out.println("Avg: -1");
 
  return 0;
 
  }
 
  public static void main() {
  int userNum1 = 0;
  int userNum2 = 0;
  int avgResult = 0;
 
  userNum1 = getUserNum();
  userNum2 = getUserNum();
 
  avgResult = computeAvg(userNum1, userNum2);
 
  System.out.println("Avg: " + avgResult);
 
  return;
  }
 }

I used many ways in another forum, but it did not work. Any solution is much appreciated!

The cause: I think the cause is that your getUserNum() method should return a user's unique ID, but instead you're defining a stub that simply returns -1 on every invocation. Solution: You should be defining these two methods, as you can see from your main() method:

userNum1 = getUserNum();
avgResult = computeAvg(userNum1, userNum2);

Hence, describe them. Here is an example of the getUserNum() stub.

public static int getUserNum() {
    System.out.println("FIXME: Finish getUserNum()");
    return -1;
}

Then leave computeAvg() up to the OP.

import java.util.Scanner;

public class MthdStubsStatistics {

 public static int getUserNum() {
 System.out.println("FIXME: Finish getUserNum()");
 return -1;
 }
 
 public static int computeAvg(int userNum1, int userNum2) {
 System.out.println("FIXME: Finish computeAvg()");
 return -1;
 }
 
 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);
 }
}
