What is the Stack.lastElement method in Java?
The
Stackclass is astack of objects. Last-In-First-Out (LIFO) The element inserted first is processed last and the element inserted last is processed first.
The lastElement() method of the Stack class returns the last element present in the Stack object.
Syntax
public E lastElement();
This method doesn’t take any arguments.
Return value
The lastElement() method returns the last element of the Stack object. If the Stack object is empty, then NoSuchElementException is thrown.
Code
import java.util.Stack;class StackLastElementExample {public static void main( String args[] ) {// Creating StackStack<Integer> stack = new Stack<>();// add elememtsstack.push(1);stack.push(2);stack.push(3);System.out.println("The stack is: " + stack);// Print last elementSystem.out.println("The last element of the stack is : " + stack.lastElement());}}
Explanation
In the code above, we create a Stack object and use the push method to add three elements, 1, 2, and 3. We then call the lastElement method on the stack object to get the last element.
stack.lastElement();
The code will return 3.
