How Can I Restart a Java AWT Application?

Restarting a Java AWT Application

In Java, like in C#, it is possible to restart an application. When an event handler is attached to a button, the following method can be used to restart the application:

public void restartApplication()
{
  final String javaBin = System.getProperty("java.home") + File.separator + "bin" + File.separator + "java";
  final File currentJar = new File(MyClassInTheJar.class.getProtectionDomain().getCodeSource().getLocation().toURI());

  /* is it a jar file? */
  if(!currentJar.getName().endsWith(".jar"))
    return;

  /* Build command: java -jar application.jar */
  final ArrayList<string> command = new ArrayList<string>();
  command.add(javaBin);
  command.add("-jar");
  command.add(currentJar.getPath());

  final ProcessBuilder builder = new ProcessBuilder(command);
  builder.start();
  System.exit(0);
}</string></string>

This method locates the Java executable, finds the application (a jar file in this case), builds a command to restart the jar, and then executes it. This process terminates the current application and starts it again, effectively restarting it.
