    Default No Output (?)

    Hello All.
    I am running this code in Eclipse. I enter a value (2) for newNum, but nothing else happens. Can someone tell me why? Thank you

    Java Code:
    import java.util.*;
    
    public class Ex5_14  
    {
    	static Scanner console = new Scanner(System.in);
    	
    	public static void main(String[] args)
    	{
    		int i;
    		int newNum;
    		int average;
    		int sum;
    		
    		sum = 0;
    		
    		for (i = 0; i < 5; i++)
    		{
    			newNum = console.nextInt();
    			sum = sum + newNum;
    		}
    
    		average = sum / 5;
    		System.out.println("The sum is " + sum);
    		System.out.println("The average is " + average);
    		
    	}
    }

    What do you expect to happen? Step through the code one line at a time from the perspective of the computer...what will happen after you are prompted for and enter the first number?

    That code doesn't prompt the user for anything; the user is just supposed to start typing; very user friendly indeed ;-)

    kind regards,

    Indeed...:) (I was using the word prompt more as a hint than anything else)
