Thread: Need help understanding why my return value is not returning back.

Here is my assignment.

Write a program that prompts the user for a positive integer n and prints “Hello World” n times. Of course, a value of n that is less than or equal to 0 is illegal. To ensure valid input, include a method
int getPos()
that prompts for a positive integer. If the value of that integer is less than or equal to 0, the method should print an appropriate message and request a positive number. When the user supplies a valid number, the method returns that number. (Hint: the break; statement is really handy in this program.)

Below is my code

/**

import java.util.*;
 
public class Problem6
{
   public static void main(String[] args)
   {
        Scanner scan = new Scanner(System.in);
        int input;
        int a;
 
        System.out.println( " Hello user! " );
        System.out.print( " Please enter the number of ireations you would like Hello World displayed. ");
        input = scan.nextInt();   
 
 
        getPos(input);
        System.out.println(input);
 
        for(a = 1; a <= input; a++)
        {
        System.out.println( " Hello World! ");    
        }
 
   }
 
   public static int getPos(int input)
   {
     Scanner scan = new Scanner(System.in);
 
     while (input <= 0)
     {
     System.out.println( " Error: Please enter a valid integer greater than 0." );
     System.out.print( " Please enter a valid number. " );
     input = scan.nextInt();
     }
 
     return input ;
 
   }
 
 
 
}

Below is my output


Hello user!
Please enter the number of ireations you would like Hello World displayed. -5
Error: Please enter a valid integer greater than 0.
Please enter a valid number. -5
Error: Please enter a valid integer greater than 0.
Please enter a valid number. -6
Error: Please enter a valid integer greater than 0.
Please enter a valid number. 55
-5


As you can see instead of returning 55 it returns my -5. FYI I placed a System.out.println tp see what the computer is doing. And I'm seeing its just not returning my value. Even if I remove my break statement in my while loop the text application just pauses....nothing happens. It does not display my Hello World statements. Any suggestions???

Thanks Again!

--- Update ---

Never mind I figured it out. lol

Here is my updated code. Like I said Norm I have really haven't worked with methods to know why it wasn't working. But yeah I completed it.
