下边有一个Java小程序。其中有两段程序不见了。你的任务是找

public class Mix4 {
  int counter = 0;
  public static void main(String [] agrs) {
    int count = 0;
    Mix4 [] m4a = new Mix4[20];
    int x = 0;

    while (                ） {
      m4a[x] = new Mix4();
      m4a[x].counter = m4a[x].counter + 1;
      count = count + 1;
      count = count + m4a[x].maybeNew(x);
      x = x + 1;
    }
    System.out.println(count + " " + m4a[1].counter);
  }
  public int maybeNew(int index) {
    if (                 ) {
      Mix4 m4 = new Mix4();
        m4.counter = m4.counter + 1;
      return 1;
    }
    return 0;
  }
}
