The push method of the Stack class can be used to add an element to the top of the Stack.
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.
public E push(E item)
This method returns the inserted element.
import java.util.Stack;class StackPushExample {public static void main( String args[] ) {// Creating StackStack<Integer> stack = new Stack<>();// add elememtsstack.push(1);System.out.println("The Stack is: " + stack);// add elememtsstack.push(2);stack.push(3);System.out.println("The Stack is: " + stack);}}
In the above code, we create a Stack object and use the push method to add the elements to the top of the stack.
