It's possible to run multiple java packages each package has a main class

Question

I have many packages that have classes in an eclipse project under src package each package has a main class each class like this

public class A extends TimerTask {
public A()
{
}
@Override
public void run() {

    new A();    } }

and each other class like this

public class MainClass 
{
public static void main(String[] args) throws InterruptedException  {   
 java.util.Timer timer = new java.util.Timer();
timer.schedule( new A(), 0, 1000);;
timer.schedule( new B(),0,1000);
}
  }

But I fail to execute two packages as the same time. Could someone suggest?

Answer 1

You could try something like this in code:

Process proc = Runtime.getRuntime().exec("java -jar another.jar");

But don't forget to properly end process, else your machine can reach the limit for file descriptors.

Answer 2

You can start them in two different threads.

Answer 3

You cannot run multiple main classes at same time. Define a flow. Such that one main class end up with starting another main.

main() {
...
...
...
callMainFromAnotherPackage();
}
