import java.util.Stack;

public class StackMethodExample {

    public static void main(String[] args) {
        peekMethod();
    }

    private static void peekMethod() {
        // creating stack
        Stack < String > stack = new Stack < > ();

        // populating stack
        stack.push("Java");
        stack.push("JEE");
        stack.push("C");
        stack.push("C++");
        stack.push("Spring");
        stack.push("Hibernate");

        // checking the top object
        System.out.println("Top object is: " + stack.peek());
    }
}
Output:
