Stack remove(Object) method in Java with Example
The Java.util.Stack.remove(Object o) method is used to remove any particular element from the Stack.
Syntax:
Stack.remove(Object o)
Parameters: This method accepts a mandatory parameter o is of the object type of Stack and specifies the element to be removed from the Stack.
Return Value: Returns True if the specified element is found and removed from the Stack, else False.
Below program illustrate the Java.util.Stack.remove(Object o) 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() boolean res = stack.remove("20"); // Print the removed element System.out.println("Was 20 removed: " + res); // Print the final Stack System.out.println("Final Stack: " + stack); }} |
Output:
Stack: [Geeks, for, Geeks, 10, 20] Was 20 removed: true 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() boolean res = stack.remove("100"); // Print the removed element System.out.println("Was 100 removed: " + res); // Print the final Stack System.out.println("Final Stack: " + stack); }} |
Output:
Stack: [10, 20, 30, 40, 50] Was 100 removed: false Final Stack: [10, 20, 30, 40, 50]
