How to run an application(process) in java as background

Question

How to run an application(process) in java as background process.It should run back to my application my application shopuld be always on foreground.I am using

p = Runtime.getRuntime().exec( "C:/Program Files/Vehicle Spy 3/vspy3Demo.exe");

I have also used "/c" like the following:

p = Runtime.getRuntime().exec( "C:/Program Files/Vehicle Spy 3/vspy3Demo.exe /c");

But it is every time opening in foreground any one can help me..

java only starts the external application. It has no control whatsoever on what the app does later on.. — TheLostMind, Jul 28 '14 at 10:47
If you are running a Swing Application then you might try [Window#setAlwaysOnTop](http://docs.oracle.com/javase/7/docs/api/java/awt/Window.html#setAlwaysOnTop(boolean)). That way your application might cover other application you are running. — Sanjeev, Jul 28 '14 at 10:52

Depending on the widget toolkit you're using (swing, swt etc), I would suggest setting a timeout (e.g. 1 second) and then bring your java app window on top again.

Example with swt

shell.getDisplay().asyncExec(new Runnable() {
  public void run() {
    shell.forceActive(); // assuming shell is your java app main window
}

Example with Swing:

java.awt.EventQueue.invokeLater(new Runnable() {
    @Override
    public void run() {
        myFrame.toFront(); // assuming myFrame is your java app main window
        myFrame.repaint();
    }
});
