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.

  2. 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);
 }
}
