Stack addElement(E) method in Java with Example
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]
