Java Program Problem

// Description: Read five positive integers and average them.
// Enter a negative integer to end the program.

import java.util.Scanner;

public class Lab5
{
public static void main (String args[])
{
       Scanner sc;
       sc = new Scanner(System.in);

   final int MAX_NUMS = 5;

       int num;       // variable to store the number
       int sum;   // variable to store the sum
       int count;    // variable to store the total numbers read
       int close;   // loop control variable

       close = 1; // initialize loop control variable

       while (<condition goes here>)
       {
           System.out.println("Calculate the Average of a Set of Five Positive Integers\n");
          
           sum = 0;       // initialize sum to 0
           count = 0; // initialize count to 0
          
           // while loop to input numbers, accumulate sum, and increment count

           // Calculate and output the average
          
          
           // Prompt user to end program or continue
           System.out.println("Enter a negative number to end the program.\n");
           System.out.println("Enter a nonnegative number to continue." );
           close = sc.nextInt();     
                                                          
}
}

   public static void main(String[] args) {
           Scanner sc = new Scanner(System.in);
           final int MAX_NUMS = 5;

           int count; // variable to store the total numbers read
           int close; // loop control variable
           close = 1; // initialize loop control variable

   while (close>=0) //check close greater than zero for user enter negative number to end program then close while loop

   sum = 0; // initialize sum to 0
count = 0; // initialize count to 0
average = 0; // initialize average to 0
  
   // while loop to input numbers, accumulate sum, and increment count
   System.out.println("Enter Five Positive Integers numbers = ");
   while(MAX_NUMS>count) //check count is less than MAX_NUMS
   {
   num = sc.nextInt(); //get user input in num variable
   sum = sum + num; //calculate sum
   count++; //increment count
   }
  
   //calculate average of numbers
average = sum/count;
   System.out.println("Average of Five Positive Integers is => "+average);
  
   // Prompt user to end program or continue
   System.out.println("Enter a negative number to end the program.");
   System.out.println("Enter a nonnegative number to continue." );
   close = sc.nextInt();
