Stack Class push() method

• push() method is available in java.util package.
• push() method is used to push the given element (ele) onto the Stack.
• push() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• push() method does not throw an exception at the time of pushing an element.

Syntax:

    public void push(Object ele);

Parameter(s):

• Object ele – represents the object to be pushed onto the top of this Stack.

Return value:

The return type of the method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void push(Object ele) method 
// of Stack

import java.util.*;

public class PushOfStack {
 public static void main(String args[]) {

  // Instantiates Stack object
  Stack s = new Stack();

  // By using push() method isto
  // push the given object at the 
  // top of the stack
  s.push(10);
  s.push(20);
  s.push(30);
  s.push(40);
  s.push(50);

  // Display Stack
  System.out.println("s:" + s);

 }
}

Output
