How many threads can you work with Exchanger class in Java?

Question

Java

For example, I will give a small program where the Exchanger class exchanges data and a small instruction is executed.

import java.util.concurrent.*;
public class MyClass {
  private static final Exchanger <Boolean> exc = new Exchanger <Boolean> ();
  private static final ExecutorService exec = Executors.newCachedThreadPool();
  
  public static void main (String [] args)throws InterruptedException {
    exec.execute(new MyRun ("Thread-1", true));
    TimeUnit.MILLISECONDS.sleep(100);
    exec.execute(new MyRun ("Thread-2", false));
    TimeUnit.SECONDS.sleep(7);
    exec.shutdownNow();
    
  }
  
  
  public static class MyRun implements Runnable {
    private boolean key;
    private String name;
    
    public MyRun (String name, boolean key){
      this.name = name;
      this.key = key;
    }
    public void run (){
      try{
        while (!Thread.interrupted()){
          if (key)
            System.out.println (name + " works");
          key = exc.exchange(key); // Обменивается данными с другим потоком.
          TimeUnit.MILLISECONDS.sleep(1500);
        }
      } catch (InterruptedException e){
        System.out.println (name + " was stopped!");
      }
    }
  }
}

My question is, is it possible to use more threads than just two?
