        // declare variables
        int num,sum=0;
        Scanner sc = new Scanner(System.in);
 
        //get a value
        System.out.print("Please enter a positive integer or a number less than 1 to end program: ");
        num = sc.nextInt();
 
        //iterate whilst a user wants to
        while(num>0)
            //accumulate the sum
          sum = sum + num;
 
        System.out.print("Please enter a positive integer or a number less than 1 to end program: ");
        num = sc.nextInt();
 
        //display the sum
        System.out.println("The sum is " + sum);

Did you have any questions?
What happens when you compile the program?
If there are no compiler errors, what happens when you execute the program?

Please post the program's output so we can see what is wrong?

Also please post the code for the complete program.
