Java Console Console

Question

They noticed that no one had answered this yet, so I thought that I would give him a chance again. Hope someone can help. Already went to study in Java, and he just said that I messed up something and could not understand, so I can not move on.

Anywho, here is my test code:

import javax.swing.JOptionPane; public class Test { public static void main(String[] args) { System.out.println("hello"); JOptionPane.showInputDialog("Enter a real number"); } } 

And here is what I get in the console:

 hello 

03:30.28 1[dbg] In DllGetClassObject
03:30.28 2[dbg] CShellExtClassFactory::CShellExtClassFactory()
03:30.28 3[dbg] CShellExtClassFactory::QueryInterface()
03:30.28 4[dbg] CShellExtClassFactory::CreateInstance()
03:30.28 5[dbg] CShellExt::CShellExt()
03:30.28 6[dbg] Looping before Zumo is running
03:30.28 7[dbg] CShellExt::QueryInterface()==>IID_IShellIconOverlayIdentifier
03:30.28 8[dbg] CShellExt::AddRef()
03:30.28 9[dbg] CShellExt::AddRef()
03:30.28 10[dbg] CShellExt::Release()
03:30.28 11[dbg] CShellExt::QueryInterface()==>IID_IShellIconOverlayIdentifier
03:30.28 12[dbg] CShellExt::AddRef()
03:30.28 13[dbg] CShellExt::Release()
03:30.28 14[dbg] Entering CShellExt::GetOverlayInfo
03:30.28 15[dbg] Icon path: C:\Program Files (x86)\Hewlett-Packard\HP CloudDrive\icons\deflated.ico
03:30.28 16[dbg] Exiting CShellExt::GetOverlayInfo successfully.

Any help would be greatly appreciated. I already tried reinstalling everything I could, including eclipse and JDK 1.7. I also noticed that this only happens when I try to use the JOptionPane dialog. I am using Windows 7 system.

Thanks guys,

Just guess, because I ran into strange AWT / Swing issues on other systems, you can try this here (sometimes the basic user interface system does not initialize properly, but as I said, this is just a guess):

 public class Test { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { System.out.println("hello"); JOptionPane.showInputDialog("Enter a real number"); } }); } } 

Using invokeLater , you force the initialization of the entire user interface system (launch EDT and the parameter bar from within the EDT), I had to use this trick, for example. so that my SDL bindings under OSX work. invokeLater initializes the entire Cocoa system for me.

This happened to me when JTextField or JTextArea was shown in my program. This only happened when compiling and running in Java 7 or higher, but not in Java 6.

I do not know why this happened, but the removal of the HP CloudDrive, which was pre-installed on my HP laptop, stopped all these lines.
