java.util.LinkedList类的removeFirst() 方法从此列表中删除并返回第一个元素。
例:
import java.util.*;public class LinkedListDemo { public static void main(String[] args) { LinkedList list = new LinkedList(); list.add("Hello"); list.add(2); list.add("Chocolate"); list.add("10"); System.out.println("LinkedList:" + list); System.out.println("First element:" + list.removeFirst()); System.out.println("LinkedList:" + list); }}
输出:
LinkedList:[Hello, 2, Chocolate, 10]First element:HelloLinkedList:[2, Chocolate, 10]
