addAll(index, collection):在指定的索引位插入一堆元素。 2.删除(删): remove(index):删除指定索引位的元素。 返回被删的元素。 3.获取(查): element get(index):通过索引获取指定元素。 int indexOf(element):获取指定元素第一次出现的索引位,如果该元素不存在返回—1;所以,通过—1,可以判断一个元素是否...

In the last section of the example theQueryelement is used to specify a result set that meets certain criteria, as in the following example, which returns a list of all the documents in a library that are written by Mary or John.
public synchronized boolean addAll(int index, Collection<? extends E> c) { // 修改次数增加 modCount++; // 合法判断 if (index < 0 || index > elementCount) throw new ArrayIndexOutOfBoundsException(index); // 转换数组 Object[] a = c.toArray(); // 插入数组长度 int numNew = a.leng...
1、voidadd(int index,Eelement) 在指定位置插入元素,后面的元素都往后移一个元素。 2、booleanaddAll(int index,Collection<? extendsE> c) 在指定的位置中插入c集合全部的元素,如果集合发生改变,则返回true,否则返回false。 意思就是当插入的集合c没有元素,那么就返回false,如果集合c有元素,插入成功,那么就返...
List<string> subList = mList.FindAll(ListFind); //委托给ListFind函数 foreach (string s in subList) { Console.WriteLine("element in subList: "+s); } 这时subList存储的就是所有长度大于3的元素。 (2)、List.Find 方法:搜索与指定谓词所定义的条件相匹配的元素,并返回整个 List 中的第一个匹配元...
