Simultaneously run java programs run on same JVM?

Question

Suppose I run two java programs simultaneously on the same machine. Will the programs run in a single instance of JVM or will they run in two different instances of JVM?

Answer 1

What you could do is use two separate threads. For exampe

new Thread() {
  public void run() {
   System.out.println("this is running separately from the main thread!");
  }
}.start();

If you want two separate programs to interact you would need to use sockets
