How to add action to a JButton to execute another Java app.? [duplicate]

Question

I have java program with interface created using Java Swing. The interface contains a JButton. I want to add Action to that button so that it should execute another Java program which I specify.

How to do that?

If you wish to run the new code in the same JRE as the one running the button, establish an URLClassLoader to the new Java app. then load and use the classes as needed. — Andrew Thompson

Try this:

  yourButton.addActionListener(new ActionListener() {

      @Override
      public void actionPerformed(ActionEvent e) {
          try {
              Process proc = Runtime.getRuntime().exec("java -jar A.jar");
          } catch (IOException ex) {

          }
      }
  });

See When Runtime.exec() won't for many good tips on creating and handling a process correctly. Then ignore it refers to exec and use a ProcessBuilder to create the process.

Huh.. I voted down before I even saw } catch (IOException ex) { } ..can I have another turn? That should be } catch (IOException ex) { ex.printStackTrace(); }
