A begginer question

[GuyG]

Hello, I'm really new in the DrJava thing, I'm learning it right now in school.. lol
I'm trying to use now drjava at home.
I downloaded the drjava from : http://drjava.org version: drjava-stable-20070828-1759, I got the compiler (JDK 1.4.2_16)
Now, I've done this newbie program:
{code}import java.util.Scanner;
public class Boom7
{
  public static void main(String[] args)
  {
    Scanner in=new Scanner(System.in);
    int a;
    System.out.println("Enter A Number");
    a=in.nextInt();
    if (a%7==0)
    {System.out.println("Boom");}
  }
}{code}

but when i try to compile it sais:

{code}3 errors found:
File: D:\תוכנות\drjava\Boom7.java  [line: 1]
Error: cannot resolve symbol
symbol  : class Scanner
location: package util
File: D:\תוכנות\drjava\Boom7.java  [line: 6]
Error: cannot resolve symbol
symbol  : class Scanner
location: class Boom7
File: D:\תוכנות\drjava\Boom7.java  [line: 6]
Error: cannot resolve symbol
symbol  : class Scanner
location: class Boom7{code}

Like it has something with the Scanner,, a problem?..
please help me what do I need to do..?

The class java.util.Scanner was introduced with JDK 1.5.  If you can  
install a newer JDK than 1.4.2 on your computer, you should be in  
business.  You can get one from java.sun.com.

ok i downloaded the 1.6 (Kit 6 Update 3) and it seems to be fine.
Just one last question.
In school when I run the program, when the drjavav need to print to the user something (lets say: println("Enter a number") it's open a window (pop-up) and in the 1.6 it just write it in the interactions (bottom screen), can i change it to the pop-up thing?.. it's more comfortable..
thx,
Guy
