Stack remove(int) method in Java with Example

The Java.util.Stack.remove(int index) method is used to remove an element from a Stack from a specific position or index.

Syntax:

Stack.remove(int index)

Parameters: This method accepts a mandatory parameter index is of integer data type and specifies the position of the element to be removed from the Stack.

Return Value: This method returns the element that has just been removed from the Stack.

Below program illustrate the Java.util.Stack.remove(int index) method:

Example 1:

// Java code to illustrate remove() when position of
// element is passed as parameter

import java.util.*;

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");

        // Output the Stack
        System.out.println("Stack: " + stack);

        // Remove the element using remove()
        String rem_ele = stack.remove(4);

        // Print the removed element
        System.out.println("Removed element: "
                           + rem_ele);

        // Print the final Stack
        System.out.println("Final Stack: "
                           + stack);
    }
}

Output:

Stack: [Geeks, for, Geeks, 10, 20]
Removed element: 20
Final Stack: [Geeks, for, Geeks, 10]

Example 2:

// Java code to illustrate remove() when position of
// element is passed as parameter

import java.util.*;

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(10);
        stack.add(20);
        stack.add(30);
        stack.add(40);
        stack.add(50);

        // Output the Stack
        System.out.println("Stack: " + stack);

        // Remove the element using remove()
        int rem_ele = stack.remove(0);

        // Print the removed element
        System.out.println("Removed element: "
                           + rem_ele);

        // Print the final Stack
        System.out.println("Final Stack: "
                           + stack);
    }
}

Output:

Stack: [10, 20, 30, 40, 50]
Removed element: 10
Final Stack: [20, 30, 40, 50]
