HELP: Counting Down Using a Loop

Posted: Sep 25, 2002 4:24 PM

Experience .... Java Beginner: I want to write a few lines where I can count down using a loop. Example: The System.out.println would be like "I have 100 dimes". Using the console (I believe) I would have a User type in a number between 1 and 100. We'll say the User types in 20 and presses Enter. The printout that the User would see would be this:
I have 100 dimes
I have 99 dimes
I have 98 dimes
I have 97 dimes .... and so on down to "I have 80 dimes".

I'm really lost as to even know where to start. Can anyone help? THANKS.

Here try this, hope this might help you

import java.io.*;

class LoopTest
{
public static void main(String[] args)
{
try
{
System.out.println("Enter a number:");
BufferedReader br = new BufferedReader(new
InputStreamReader(System.in));
String str;
str = br.readLine();
int num = new Integer(str).intValue();
if(num<0)
{
System.out.println("Error: Enter Positive Values Only");
return;
}
num = 100-num;
for(int i=100;i>=num;i--)
System.out.println("I have "+i+" dimes");
}
catch(IOException io)
{
io.printStackTrace();
}
catch(NumberFormatException e)
{
System.out.println("Enter Integer only");
}
}
}
