Code with using util.Scanner.nextInt() complies but not run

[mals@nash-inc.com]

Hi:

I have Java6 intalled.

Using TextPad, I can compile code with java.util.Scanner.nextInt() in it, however, when I try to run the code it error out every time.

The code is:

import java.util.Scanner;
public class ScannerApp
{
static Scanner sc = new Scanner(System.in);
public static void main(String[] args)
{
System.out.print("Enter an integer: ");
int x = sc.nextInt();
System.out.println("You entered " + x + ".");
}
}

The error message is:

Enter an integer: Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Scanner.java:838)
at java.util.Scanner.next(Scanner.java:1461)
at java.util.Scanner.nextInt(Scanner.java:2091)
at java.util.Scanner.nextInt(Scanner.java:2050)
at ScannerApp.main(ScannerApp.java:11)

I can compile and run the above code from DOS prompt (command window).

TIA

If you run the Java program from textpad, System.in is NOT connected to the correct source STDIN.

The only solution I know is NOT to run the Java program from within textpad.

That sucks!!! Are you saying I shouldn't run Java programs from TextPad?

I can run kinds of java programs from TextPad. Just that, at this moment, I can't run any type of a program that has java.util.Scanner.nextInt() in the code.

Those that expect input from STDIN.

Textpad is NOT a Java IDE. If you want a Java IDE, go to www.eclipse.org
Then you can not only run your programs from the IDE, you can even debug them and have many other Java-specific features (like code completion, instant error messages and so on)

Okay, now I understand.
Thank you for taking the time.
