The addElement(E) method of Stack Class is used to append the element passed as a parameter to this function at the end of the Stack.
Syntax:
boolean addElement(E obj) Here, E is the type of elements maintained by this container.
Parameters: This function accepts a parameter E obj which is the object to be added at the end of the Stack.
Return Value: The method returns True if at least one action of append is performed, else False.
Below program illustrate the Java.util.Stack.addElement() method:
Example 1:
// Java code to illustrate boolean addElement() import java.util.*;import java.util.ArrayList; public class GFG { 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("The Stack is: " + stack); // Appending "GeeksForGeeks" to the Stack stack.addElement("GeeksForGeeks"); // Clearing the Stack using clear() and displaying 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, GeeksForGeeks]
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); // Displaying the Stack System.out.println("The Stack is: " + stack); // Appending 100 to the Stack stack.addElement(100); // Clearing the Stack using clear() and displaying 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]
