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]
