LinkedList pop/push element
In this chapter you will learn:
Poll, pop and push element to a LinkedList
We can use LinkedList
as a stack.
A stack is a computer data structure that element can only come in and out from one end
of a list. First in last out, or Last in first out.
E pop()
Pops an element from the stack represented.void push(E e)
Pushes an element onto the stack represented.
import java.util.LinkedList;
/* ja v a 2s .c o m*/
public class Main{
public static void main(String args[]) {
LinkedList<String> ll = new LinkedList<String>();
ll.push("A");
ll.push("java2s.com");
ll.push("B");
ll.push("C");
ll.push("java2s.com");
System.out.println(ll);
System.out.println(ll.pop());
System.out.println(ll);
}
}
The code above generates the following result.
