String address="上海^上海市@闵行区#吴中路"; String[] splitAddr=address.split("\\^|@|#"); System.out.println(splitAddr[0]+splitAddr[1]+splitAddr[2]+splitAddr[3]); 空值的存储 如果split(String s)函数产生了空值,那么不会存到数组中。可以通过使用它的重载函数split(";",-1)实现空值的保存。

addAll() 方法,通过将collection 中的数据转换成 Array[] 然后添加到elementData 数组,从而完成整个集合数据的添加。在整体上没有什么特别之初,这里的collection 可能会抛出控制异常 NullPointerException 需要注意一下。 1.3.4 addAll(int index,Collection<? extends E> c) ...

In such a case, like in our example, the actual value is split up along the | characters. The comma used as a list separator, and the values separator | can be redefined. In the above case, the for loop uses three-loop variables, $name, $type`, and$args. The start with a$` ...
