Stack add(Object) method in Java with Example
The add(Object) method of Stack Class appends the specified element to the end of this Stack.
Syntax:
boolean add(Object element)
Parameters: This function accepts a single parameter element as shown in the above syntax. The element specified by this parameter is appended to end of the Stack.
Return Value: This method returns True after successful execution, else False.
Below program illustrates the working of java.util.Stack.add(Object element) method:
Example 1:
// Java code to illustrate boolean add(Object element)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 present Stack System.out.println("The Stack is: " + stack); // Adding new elements to the end stack.add("Last"); stack.add("Element"); // Printing the new Stack System.out.println("The new Stack is: " + stack); }} |
Output:
The Stack is: [Geeks, for, Geeks, 10, 20] The new Stack is: [Geeks, for, Geeks, 10, 20, Last, Element]
Example 2:
// Java code to illustrate// boolean add(Object element) 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 present Stack System.out.println("The Stack is: " + stack); // Adding new elements to the end stack.add(100); stack.add(200); // Printing the new Stack System.out.println("The new Stack is: " + stack); }} |
Output:
The Stack is: [10, 20, 30, 40, 50] The new Stack is: [10, 20, 30, 40, 50, 100, 200]
