incompatible types int need string

Question

I need it to be an int to return but it keeps saying

----jGRASP exec: javac -g CSCD210Lab8Functions.java

CSCD210Lab8Functions.java:118: incompatible types
found   : int
required: java.lang.String
      return finalExam;





 public static String readFinalScore(Scanner kb)
   {int finalExam;
      do{
         kb.nextLine();
         System.out.print("Enter the score of the final-->");
         finalExam = kb.nextInt();
         kb.nextLine();
         if (finalExam<0)
         {System.out.print("Invalid answer please try again " );}
      }while(finalExam<0);
      return finalExam;

i casted it as an int and then kb.nextInt not sure why it's freaking out

Answer 1

public static String readFinalScore(Scanner kb) // return type String
{int finalExam; // finalExam is int
...
return finalExam;   // returning int value when it expects String

return type is String and finalExam is int.

Change to

public static int readFinalScore(Scanner kb)

Answer 2

You're returning an int when it wants a String

Change:

public static String readFinalScore(Scanner kb)

Into:

public static int readFinalScore(Scanner kb)

Answer 3

If you meant to declared your method to return String, java won't automatically convert an int to a String.

Change your return statement to:

return String.valueOf(finalExam);

Or you can "cheat" too:

return finalExam + "";

---

However, if you really want to return an int, then declare your method like this:

public static int readFinalScore(Scanner kb)

Your current method code will then work.

Answer 4

Your return statement do not match..

So you can use Integer.toString(finalExam) to return String type

Hope it helps..

Answer 5

Your return declaration is incorrect. you should change to int instead of String.

public static int readFinalScore(Scanner kb)

   return finalExam ;
}
