Java Examples - Get Elements of a Linked List
Java ExamplesThe following example demonstrates using the top() and pop() methods to get elements of a linked list:
Main.java File
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());
}
}
The output of the above code is:
