The Java.util.Stack.elementAt(int pos) method is used to fetch or retrieve an element at a specific index from a Stack.
Syntax:
Stack.elementAt(int pos)
Parameters: This method accepts a mandatory parameter pos of integer data type that specifies the position or index of the element to be fetched from the Stack.
Return Value: The method returns the element present at the position specified by the parameter pos.
Below programs illustrate the Java.util.Stack.get() method:
Program 1:
// Java code to illustrate elementAt() 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( "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.elementAt( 3 )); } } |
Stack: [Geeks, for, Geeks, 10, 20] The element is: 10
Program 2:
// Java code to illustrate elementAt() method import java.util.Stack; 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( 1 ); stack.add( 2 ); stack.add( 3 ); stack.add( 4 ); stack.add( 5 ); // Displaying the Stack System.out.println( "Stack: " + stack); // Fetching the specific element from the Stack System.out.println( "The element is: " + stack.elementAt( 1 )); } } |
Stack: [1, 2, 3, 4, 5] The element is: 2
