5th line @Override Tells that you are overriding a method from a class. Function overridingĀ is a feature that allows us to have a sameĀ functionĀ in child class which is already present in the parent class. A child class inherits the data members and memberĀ functionsĀ of parent class, but when you want toĀ overrideĀ a functionality in the child class then you can useĀ function overriding. credit - beginnersbook

The toString method already exist for the string class and it is being overridden to perform a specific function for this code. The @Override is to help the compiler

what do you mean? Public means you can access it anywhere, String tells the return type of function name toString()

Atul Well, if you don't want functions means its not overriding!

The toString() method is defined in the Object class which is the superclass of all classes. When you print any reference data type (array or object), the toString() is automatically invoked. This method returns a string containing the memory location of the array/object on the heap. But, suppose you have a class Employee and when you print an object of the class, you want to print the employee's salary, age, name. In such a case, you can override the method. For example - @Override public String toString() { return "Name : " + employee.name; } The annotation makes sure that the method is overriden correctly.
