Java Method Stubs

Question

This is what I have to do:

Define stubs for the methods called by the below main(). Each stub should print \"FIXME: Finish methodName()\" followed by a newline, and shou

Answer 1

import java.util.Scanner;

public class MthdStubsStatistics {

/* Your solution goes here */
public static int getUserNum () { System.out.println("FIXME: Finish getUserNum()");
return -1;
}
public static int computeAvg(int userNum1, int userNum2){ int avgResult = (userNum1 + userNum2)/2; System.out.println("FIXME: Finish computeAvg()"); return -1;
} 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;
} }

Answer 2

A method stub in this sense is a method with no real substance, i.e. it's not doing what it is intended to do. Your getUserNum() method should return a user's unique ID, but instead you're defining a stub that simply returns -1 on every invocation.

You can tell from your main() method, you're supposed to be defining these two methods:

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

So, define them. Here's what the getUserNum() stub would look like.

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

I'll leave computeAvg() up to the OP.

Answer 3

import java.util.Scanner;

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

   
   public static int computeAvg(int a, int b) {
      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);
   }
}
