根据给定条件从ArrayList中删除对象

您必须使用和

Iterator

remove

Iterator<Pulse> iter = pulseArray.iterator();while (iter.hasNext()) {  Pulse p = iter.next();  if (p.getCurrent()==null) iter.remove();}

注意，迭代器＃删除功能被认为是optionnal，但它
是 由ArrayList的迭代器来实现。

这是ArrayList.java中此具体功能的代码：

765         public void remove() {766  if (lastRet < 0)767      throw new IllegalStateException();768  checkForComodification();769 770  try {771      ArrayList.this.remove(lastRet);772      cursor = lastRet;773      lastRet = -1;774      expectedModCount = modCount;775  } catch (IndexOutOfBoundsException ex) {776      throw new ConcurrentModificationException();777  }778         }779 780         final void checkForComodification() {781  if (modCount != expectedModCount)782      throw new ConcurrentModificationException();783         }784     }

这

expectedModCount = modCount;
