Question

I keep getting the error below in zbooks. How can I fix this. Thank You JAVA

zyLabsUnitTest.java:14: error: cannot find symbol s = MidtermProblems.difference(75, 75);

^ symbol: method difference(int,int) location: class MidtermProblems 1 error

import java.lang.Math;

public class MidtermProblems {

public static String difference(int a, int b) {

int diff = Math.abs(a - b);

String ans = "";

   if (diff == 0) {

ans = "EQUAL";

   } else if (diff > 10) {

ans = "Big Difference " + diff;

   } else if (diff <= 10) {

ans = "Small Difference " + diff;

        }

        return ans;
   }
}

Answer 1

Before using s we have to declare its data type . so, we have to declare 's' as String datatype

Note: in my answer screen shot , in the 19th line I added the datatype to 's' as String

Note: if you need use public before class name

Source Code:

import java.lang.Math;

class MidtermProblems {
   public static String difference(int a, int b) {
       int diff = Math.abs(a - b);
       String ans = "";
       if (diff == 0) {
               ans = "EQUAL";
           }
       else if (diff > 10) {
               ans = "Big Difference " + diff;
           }
       else if (diff <= 10) {
               ans = "Small Difference " + diff;
           }
       return ans;
   }
   public static void main(String[] args) {
      String s = MidtermProblems.difference(75, 75);
      System.out.println(s);
   }
}
