Concurrency Problems
Because threads run at the same time as other parts of the program, there is no way to know in which 
order the code will run. When the threads and main program are reading and writing the same variables, 
the values are unpredictable. The problems that result from this are called concurrency problems.
*/
//A code example where the value of the variable amount is unpredictable
public class JavaThread3 extends Thread {
    public static int amount = 0;
    public static void main(String[] args) {  
    JavaThread3 thread = new JavaThread3();
    thread.start();
    System.out.println(amount);
    amount++;
    System.out.println(amount);
  }

  public void run() {
    amount++;
  }
    
}
