Syntax:
Java
Java
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:
Example 2:
Stack: [Geeks, for, Geeks, 10, 20] Removed element: 20 Final Stack: [Geeks, for, Geeks, 10]
// 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]
