Java Program stopped working

**Sheila Mae Mercado** · March 16th, 2014, 07:25 AM

Hi. I hope someone could help me on this. I have a java program which would display a message dialog box. The problem is it would stopped working before even displaying the message dialog box. This is my code.
import javax.swing.JOptionPane;

public class HelloDialog
{
public static void main(String [] args)
{
JOptionPane.showMessageDialog(null, "Hello World!");
}
}

There is a pop-up window which would say "Java(TM) Platform SE binary has stopped working."
I am using textpad.
What should I do with this?

Open a command prompt window, change to the directory with the HelloDialog.class file and enter:
java HelloDialog

copy the full contents of the command prompt window and paste it here. If there are other error messages we can see.

I am not sure if I'm doing the right thing on the command prompt.. I'm sorry.

Could not find or load main class HelloDialog

The java program could not find the HelloDialog.class file.
Check that the file exists. It is created by the javac program.
Look at the tutorial for help: "Hello World!" for Microsoft Windows (The Java™ Tutorials > Getting Started > The "Hello World!" Application)

I followed the steps on your link and when it compiles, I typed dir in the command and this is the result

I just get the same result just like when I am using textpad. It would still stop working

--- Update ---

When I am coding with only text as output, it would work properly but when I tried the dialog box, it would stop working

The only thing I can think of is to uninstall java and reinstall it.

**jashburn** · March 16th, 2014, 07:40 PM

I've looked this up a bit, and it seems there can be a number of causes.

Firstly, your Windows version is 6.1.7601. Do you have Windows 7 SP1 or Windows Server 2008 R2 SP1?

Secondly, copy the source code at http://docs.oracle.com/javase/tutori...orldSwing.java, and compile and run it via command line. Do you still see the "Java(TM) Platform SE binary has stopped working" error? If you do, grab a screenshot of the error message pop up window and post it here.

There are a few things that you can try in the following order.

1. End stale/conflicting java process

a) Press Alt+Ctrl+Del.
b) Start up Task Manager.
c) Under Process Tab, locate "javaw.exe [Java™ Platform SE Library]" or "java.exe".
d) If there is such a process, select it and click on the "End Process" button. If there are more than 1, repeat for all of them.

Check if the problem recurs.

2. Clean virus infection

It seems that virus infection in your PC can cause this. Try downloading Microsoft Safety Scanner - Free Virus Scan with the Microsoft Safety Scanner and scan your PC.

After that reboot your PC, and check if the problem recurs.

3. 32/64-bit Java

Run "java -version". See if it mentions "64-Bit" anywhere in the command output.

4. Reinstall Java

As Norm suggested, try uninstalling and reinstalling Java. As you uninstall Java, check to see if you have multiple versions of Java installed. If you have, uninstall all of them.

Also, if from #3 the output from the "java -version" command mentions "64-Bit", after uninstalling Java, try installing the 32-bit version.

Good luck!
