翻看 Java10 里面的 ArrayList 源码,remove 方法里面有个 found: {} 这是什么意思呢?

 public boolean remove(Object o) { final Object[] es = elementData; final int size = this.size; int i = 0; found: { if (o == null) { for (; i < size; i++) if (es[i] == null) break found; } else { for (; i < size; i++) if (o.equals(es[i])) break found; } return false; } fastRemove(es, i); return true; }
