第1题:

public class X implements Runnable {  private int x;  private int y;  public static void main(String [] args) {  X that = new X();  (new Thread( that )).start();  (new Thread( that )).start();  }  public void run() {  for (;;) {  synchronized (this) {  x++;  y++;  }  System.out.println(Thread.currentThread().getName() +  “x = “ + x + “, y = “ + y);  }  }  }   What is the result?()  

  • A、 Compilation fails.
  • B、 The program prints pairs of values for x and y that might not always be the same on the same line (for example, “x = 2, y = 1”).
  • C、 The program prints pairs of values for x and y that are always the same on the same line (for example, “x = 1, y = 1”).    In addition, each value appears only once (for example, “x = 1, y = 1” followed by “x = 2, y = 2”).    The thread name at the start of the line shows that both threads are executing concurrently.
  • D、 The program prints pairs of values for x and y that are always the same on the same line (for example, “x = 1, y = 1”).     In addition, each value appears only once (for example, “x = 1, y = 1” followed by “x = 2, y = 2”).    The thread name at the start of the line shows that only a single thread is actually executing.
