Thread: Eclipse question from newbie - reading keyboard

I just installed Eclipse and am wondering if the following is normal. When I run a java program in Eclipse it cannot "read the keyboard" but it can print variable values okay. My program works fine if instead of using the Eclipse IDE I instead run in a cmd window in XP.


So it is the while loop at the bottom of my code that is ignored by Eclipse. I'm a newbie and am wondering if this is normal? Thanks. Maybe I must run it a special way?

import java.text.DateFormat;
import java.util.*;
 
 
 
public class eliz9
 
{
 
 
 
 
 
	public static void main(String[] args)
 
	{
 
 
		int purp =2222;
 
		System.out.println(purp);
		Scanner keyboard = new Scanner(System.in);
	    String[] four = {"Tell me more about"};
 
	    System.out.println(   System.currentTimeMillis() );
	    double a = System.currentTimeMillis();
	    int z=0;
	    while ( z < 999922227)
	    {
	    	z++;
	    }	
 
 
 
 
	    System.out.println(   System.currentTimeMillis() );
	    double b = System.currentTimeMillis();
	    double c= b-a;
	    System.out.println( c);
 
 
	     z = 5;
 
	    while ( z < 7)
		    {
		    Scanner myScanner = new Scanner(System.in);
		     int xinputNumber = myScanner.nextInt();
                    z= xinputNumber;
		    }
		// TODO Auto-generated method stub
 
	}

Hello - in the cmd window the "while" loop will accept a key such as "1" or "2" and break out with "7" or greater and this works. But in Eclipse my keystroke inputs are not read, it seems.

I'm thinking you just need to click in the console window at the bottom of eclipse to give it focus. If it does not have focus then it won't take input.

Thanks to all. I fixed the Scanner and used the focus and it now works as expected. Cheers.
