Thread: can someone help me with this while loop assignment

im doing an assignment for java intro class and am getting the results i need just dont know if this is layed out right or not

here is what were supposed to do

Write a program that will read an unspecified number of positive numbers from the keyboard and determine the sum and the average of these numbers. A negative number should be used to terminate the input, i.e. when the program encounters a negative number, it should stop prompting and reading data and at that point should output the results. Note that the negative number that terminates the looping should not be added to the sum and certainly should not be counted as one of the valid numbers.
A sample program run would look like this :
Enter a number that is positive or zero 3
Enter a number that is positive or zero 5
Enter a number that is positive or zero 6
Enter a number that is positive or zero 4
Enter a number that is positive or zero -1
You have entered 4 numbers
Total of the numbers you entered is 18
Average of the numbers is 4.5

The program should use a WHILE loop to accomplish it's mission.

when i run it it constantly keeps asking me to put in a number when i only want to enter about 4 or 5 numbers and and then calculate the sum and average of those #'s

btw this is what i got

import java.util.Scanner ; 
 
public class Assign6_Roberts{
 
	public static void main (String [] args){
		//Create Scanner
		Scanner input = new Scanner(System.in);
 
 
		int number = 0, sum = 0, numamount = 0; // You can change the variable names.
		while(number >-1)
		{ // Begin while statement
		System.out.println("Enter  a  number  that  is  positive  or  zero: "); // Get the next number
		number = input.nextInt();
 
		sum = sum+number; // Get the sum so far.
		numamount++; // Get the number amount so far.
		} // End while statement.
		double average = sum/numamount;  //Get the average.
		System.out.println("You have entered " + numamount + " numbers"); // Output amount of numbers
		System.out.println("Total of the numbers you entered is " + sum); // Output sum of numbers
		System.out.println("Average of the numbers is " + average); // Output average of numbers.
	}
}

The reason you are entering more then 5 number is because the while loop will go until someone enters a number<1. Instead the while loop should check if numamount < 5. Then have an if statement check if the entered number<1.

 public static void main(String[] args) {
        // TODO code application logic here
         //Create Scanner
        Scanner input = new Scanner(System.in);
 
 
        int number = 0, sum = 0, numamount = 0; // You can change the variable names.
        while(numamount < 5)
        { // Begin while statement
        System.out.println("Enter  a  number  that  is  positive  or  zero: "); // Get the next number
        number = input.nextInt();
        if (number < 0){
         System.out.println("you have Entered an invalid number, please enter again: ");
         number = input.nextInt();
        }
        sum = sum+number; // Get the sum so far.
        numamount++; // Get the number amount so far.
        } // End while statement.
        double average = sum/numamount;  //Get the average.
        System.out.println("You have entered " + numamount + " numbers"); // Output amount of numbers
        System.out.println("Total of the numbers you entered is " + sum); // Output sum of numbers
        System.out.println("Average of the numbers is " + average); // Output average of numbers.
    }
