There was a student who always pronounces "University" as "Univerkity". His teacher got angry and called the parents and asked to know the reason. Teacher got shocked as they are pronouncing "Capacity" as "Capakity" Later she called student's grand parent with curiosity. And agian shocked as they pronounced "publicity" as "publikity". So it is the duty of the teacher to override the speaking mechanism of the student. As she can't change parent's method and has access to student method. If you want to write your own implementation for any method, you should use overriding, so that it's child classes / it's objects can use the new mechanism. read less

when a class that extends from another class wants to use most of the feature of the parent class and wants to implement specific functionality in certain cases. We know method overriding will be coming in inheritance. Consider a mother and her daughter. Lets think mothers will cook, so her daughter will also cook. One day mother cooked a biryani for her daughter. By using the method cookBriyani(rice,vegetables,water,salt). { // mother style of cooking } But her daughter didn’t like it. So her daughter decided to prepare biryani by herself. She is also going to use same ingredients but she is going to prepare in her style. Daughter method is cookBriyani(rice,vegetables,water,salt){ // daughter style of cookling } Daughter made also biryani so without changing the name i.e cookBriyani(), also she used same ingredients (i.e rice,vegetables,water,salt) i.e same parameter but she prepared in different style. read less

Override can be achieved only in subclass. This can be used to change the behavior of super class method in child class.

Method overriding is used to provide the specific implementation of the method that is already provided by its super class. Consider a scenario, Bank is a class that provides functionality to get rate of interest. But, rate of interest varies according to banks. For example, Bank-1, Bank-2 and Bank-3...

Is synchronized keyword necessary, in Java, if everything that is modified in a function is local to that function?
No, it is not required if you make sure whatever parameters are updated/modified will be done as atomic references/operations. Atomicity is an alternative to syncronizatiom.
