Program freezes while running executables.

Question

I'm working on a java installer & while doing the install the program window freezes until it's done. I'm trying to figure out how to make it not freeze so that I can implement some kind of progress bar. Here is the codes I'm using to install java I'm using the same code for everything.
     public void java(String curDir) {
          try {
            String prop = install.ReadProps("WinJava");
               String command = "\"" + curDir
                         + "\\" + prop + "\" /s /v\"/qb\"";
               System.out.println(command);
               install.runCommand(command);
          } catch (Throwable e) {
               e.printStackTrace();
     }

And you, use a non-deprecated API: [http://java.sun.com/javase/6/docs/api/java/lang/Thread.html].
