The Java.util.Stack.lastElement() method in Java is used to retrieve or fetch the last element of the Stack. It returns the element present at the last index of the Stack.
Syntax:
Stack.lastElement()
Parameters: The method does not take any parameter.
Return Value: The method returns the last element present in the Stack.
Below programs illustrate the Java.util.Stack.lastElement() method:
Program 1:
// Java code to illustrate lastElement() 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 into the Stack
stack.add( "Welcome" );
stack.add( "To" );
stack.add( "Geeks" );
stack.add( "4" );
stack.add( "Geeks" );
// Displaying the Stack
System.out.println( "Stack: " + stack);
// Displaying the last element
System.out.println( "The last element is: "
+ stack.lastElement());
}
} |
Output:
Stack: [Welcome, To, Geeks, 4, Geeks] The last element is: Geeks
Program 2:
// Java code to illustrate lastElement() 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 into the Stack
stack.add( 10 );
stack.add( 15 );
stack.add( 30 );
stack.add( 20 );
stack.add( 5 );
// Displaying the Stack
System.out.println( "Stack: " + stack);
// Displaying the last element
System.out.println( "The last element is: "
+ stack.lastElement());
}
} |
Output:
Stack: [10, 15, 30, 20, 5] The last element is: 5
