Java program to demonstrate example of Object Class toString() method

import java.util.LinkedList;

public class ObjectClass {
    public static void main(String[] args) {

        // Create an object of Float type

        Float fl = new Float(10.f);

        // Create an object of linked list type

        LinkedList ll = new LinkedList();

        // Add few elements in Linked List

        ll.add(10);
        ll.add(20);

        // Display String representation of the objects

        System.out.println("The String representation of the Object fl is: " + fl.toString());
        System.out.println("The String representation of the Object ll is: " + ll.toString());
    }
}

Output

D:\Programs>javac ObjectClass.java

D:\Programs>java ObjectClass
The String representation of the Object fl is :10.0
The String representation of the Object ll is :[10, 20]
