![]() Then at the runtime it runs the method specific for that object. Therefore in the above example, the program will compile properly since Company class has the method move. However in the runtime JVM figures out the object type and would run the method that belongs to that particular object. ![]() Reason: In compile time the check is made on the reference type. In the above example you can see that the even though b is a type of Company it runs the move method in the eBay class. } Result: This is Address of Crunchify Company. ("This is Address of Crunchify Company.") Sample Example: package Ĭompany a = new Company() // Company reference and objectĬompany b = new eBay() // Company reference but eBay objectĪ.address() // runs the method in Company classī.address() // Runs the method in eBay class The overriding method can throw narrower or fewer exceptions than the overridden method. However the overriding method should not throw checked exceptions that are new or broader than the ones declared by the overridden method. ![]() An overriding method can throw any uncheck exceptions, regardless of whether the overridden method throws exceptions or not.A subclass in a different package can only override the non-final methods declared public or protected.A subclass within the same package as the instance’s superclass can override any superclass method that is not declared private or final.If a method cannot be inherited then it cannot be overridden.A method declared static cannot be overridden but can be re-declared.A method declared final cannot be overridden.Instance methods can be overridden only if they are inherited by the subclass.For example: if the super class method is declared public then the over-ridding method in the sub class cannot be either private or protected.The access level cannot be more restrictive than the overridden method’s access level.The return type should be the same or a subtype of the return type declared in the original overridden method in the super class.The argument list should be exactly the same as that of the overridden method.In java, a method can only be written in Subclass, not in same class.Last week I wrote Java Method Hiding and Overriding: Override Static Method in Java here.īut I realized, it’s worth sharing some more information on Java Method Overriding.
