To avoid concurrency problems, it is best to share as few attributes between threads
as possible. If attributes need to be shared, one possible solution is to use the isAlive() method
of the thread to check whether the thread has finished running before using any attributes that the thread can change.
*/

//Use isAlive() to prevent concurrency problems:
public class JavaThread4 extends Thread {
    public static int amount = 0;

  public static void main(String[] args) {
    JavaThread4 thread = new JavaThread4();
    thread.start();
    // Wait for the thread to finish
    while(thread.isAlive()) {
    System.out.println("Waiting...");
  }
  // Update amount and print its value
  System.out.println("Main: " + amount);
  amount++;
  System.out.println("Main: " + amount);
  }
  public void run() {
    amount++;
  }
