You have written a class called Frog and have not written a toString method. Frog f = new Frog(); System.out.println(f); What happens when the code above is executed? "Ribbit" is printed. Error - a class cannot be instantiated without the toString method. Error - Frog has no toString method. Nothing happens. The toString method in Object is called.

The correct answer is: 'The toString method in Object is called.' If you don't explicitly write a ToString() method in your class, the ToString() method in the parent class is called. Your own 'ToString()' method would overload the parent Object 'ToString()' method.

Answer:

The toString method in Object is called.

Explanation:

toString method in a class is a special method that will be invoked when we try to use println() method to display the value of a class instance. toString method is usually used to show the current state of attribute in a class instance.

However, if there is no toString method defined in a class, the toString method in the parent class will be called. In Java, all classes are inherited from Object class and therefore the Object class is a parent class and its toString method will be invoked if the toString method is missing from its child class.
