Java 范例 - 获取链表的元素
使用 top() 和 pop() 方法来获取链表的元素
import java.util.*; public class Main { private LinkedList list = new LinkedList(); public void push(Object v) { list.addFirst(v); } public Object top() { return list.getFirst(); } public Object pop() { return list.removeFirst(); } public static void main(String[] args) { Main stack = new Main(); for (int i = 30; i < 40; i++) stack.push(new Integer(i)); System.out.println(stack.top()); System.out.println(stack.pop()); System.out.println(stack.pop()); System.out.println(stack.pop()); } }
编译运行以上 Java 代码,输出结果如下
