Stack elementAt() method in Java with Example

Last Updated : 24 Dec, 2018

The Java.util.Stack.elementAt(int pos) method is used to fetch or retrieve an element at a specific index from a Stack.

Syntax:

Stack.elementAt(int pos)

Parameters: This method accepts a mandatory parameter pos of integer data type that specifies the position or index of the element to be fetched from the Stack.

Return Value: The method returns the element present at the position specified by the parameter pos.

Below programs illustrate the Java.util.Stack.get() method:

Program 1:

// Java code to illustrate elementAt() method 
import java.util.Stack; 
  
public class StackDemo { 
    public static void main(String args[]) 
    { 
  
        // Creating an empty Stack 
        Stack<String> stack = new Stack<String>(); 
  
        // Use add() method to add elements in the Stack 
        stack.add("Geeks"); 
        stack.add("for"); 
        stack.add("Geeks"); 
        stack.add("10"); 
        stack.add("20"); 
  
        // Displaying the Stack 
        System.out.println("Stack: "
                           + stack); 
  
        // Fetching the specific element from the Stack 
        System.out.println("The element is: "
                           + stack.elementAt(3)); 
    } 
} 

Output:

Stack: [Geeks, for, Geeks, 10, 20]
The element is: 10

Program 2:

// Java code to illustrate elementAt() method 
import java.util.Stack; 
  
public class StackDemo { 
    public static void main(String args[]) 
    { 
  
        // Creating an empty Stack 
        Stack<Integer> stack = new Stack<Integer>(); 
  
        // Use add() method to add elements in the Stack 
        stack.add(1); 
        stack.add(2); 
        stack.add(3); 
        stack.add(4); 
        stack.add(5); 
  
        // Displaying the Stack 
        System.out.println("Stack: " + stack); 
  
        // Fetching the specific element from the Stack 
        System.out.println("The element is: "
                           + stack.elementAt(1)); 
    } 
} 

Output:

Stack: [1, 2, 3, 4, 5]
The element is: 2
