Thread: JOptionPane Question/ Printing

I am not sure what I am doing that is causing it not to print. I havent completly finished the program yet, I have decided to just try and get it to print right first...haha. My math was right but it wouldnt loop once I set it up to loop it won't print...any guidance would be appreciated.




This is what I am working on.....right now I am just trying to get it to print message1 when the input is zero. Any help would be appreciated. Here is what I have so far.

 
import java.util.Scanner;//program that uses a class scanner
import java.lang.Float;
import javax.swing.JOptionPane; //Dialog Boxes
 
//Program that reads numbers 
 
public class NumberCounter
{
	public static void main(String args[])
	{
		Scanner input = new Scanner( System.in );
 
		int Entries = 1;    //Total of all numbers entered
		int Total = 0;   //Total sum of numbers
		int Large;  //Largest number in group
		int Small;  //Smallest number in group
		float Average;        //Average of numbers entered	
 
	do{
		String counter=	
		JOptionPane.showInputDialog("Input numbers to check:");	
		float Number1 = Float.parseFloat(counter);	
 
		Entries ++;
		Total += Number1;
            	                     Average = Total / Entries;
 
	}while(Number1 != 0);
 
                     String message1=
		String.format("Total number of Entries : %d\n Numbers entered: %.0f\n Average of all numbers:%.0d\n 
                                          Total sum of all numbers:%d", Entries, Number1, Average, Total);
		JOptionPane.showMessageDialog(null, message1);
 
	} //end method main
 
} //end class NumberCounter

i edited your code sir...

you have Scanner class .. why is it there? its only use for console input..

Thanks for the help I was able to figure out what I was doing wrong.....
I really appreciate how you broke it down in the text for me that went a long way for me....thanks again

I have scanner class just because I am new to java and am still learning.
