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 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.
