Return Value: The method returns the element present at the position specified by the parameter index.



Below programs illustrate the Java.util.Stack.get() method:

Program 1:




// Java code to illustrate get() method
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");
  
        // Displaying the Stack
        System.out.println("Stack: " + stack);
  
        // Fetching the specific element from the Stack
        System.out.println("The element is: "
                           + stack.get(2));
    }
}
Output:
Stack: [Geeks, for, Geeks, 10, 20]
The element is: Geeks

Program 2:




// Java code to illustrate get() method
import java.util.Stack;
  
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("1");
        stack.add("2");
        stack.add("3");
        stack.add("10");
        stack.add("20");
  
        // Displaying the Stack
        System.out.println("Stack: "
                           + stack);
  
        // Fetching the specific element from the Stack
        System.out.println("The element is: "
                           + stack.get(4));
    }
}
Output:
Stack: [1, 2, 3, 10, 20]
