以下实例演示了使用 top() 和 pop() 方法来获取链表的元素：
Main.java 文件
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());
}
}
以上代码运行输出结果为：
39 39 38 37
