Add an Element to a Stack in Java

An element can be added into the stack by using the java.util.Stack.push() method. This method pushes the required element to the top of the stack. The only parameter required for the Stack.push() method is the element that is to be pushed into the stack.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.util.Stack;
public class Demo {
   public static void main (String args[]) {
      Stack stack = new Stack();
      stack.push("Apple");
      stack.push("Mango");
      stack.push("Guava");
      stack.push("Pear");
      stack.push("Orange");
      System.out.println("The stack elements are: " + stack);
   }
}

Output

The stack elements are: [Apple, Mango, Guava, Pear, Orange]

Now let us understand the above program.

The Stack is created. Then Stack.push() method is used to add the elements to the stack. Finally the stack is displayed. A code snippet which demonstrates this is as follows −

Stack stack = new Stack();
stack.push("Apple");
stack.push("Mango");
stack.push("Guava");
stack.push("Pear");
stack.push("Orange");
System.out.println("The stack elements are: " + stack);
