Generalization in Java with Example Program The process of converting subclass type into superclass type is called generalization in java. Usually, generalizations are discovered after the factthe derived classes are written first and the base class is determined last. We can calculate electricity bills using static values, command-line argument, method and functions, user-defined method, and do-while and for loop. Common structure and behaviour are used from the specializtion to the generalized class. Words like house, chair, lawn, and video are all examples of concrete words.However, abstract words are the opposite of concrete words.

These are traditional software that we need to install on every machine. JavaTpoint offers too many high quality services. If a class implements Serializable interface then all its sub classes will also be serializable. The Externalizable interface provides two methods: If you don't want to serialize any data member of a class, you can mark it as transient. If a class has a reference to another class, all the references must be Serializable otherwise serialization process will not be performed. public: accessible in all class in your application. Encapsulated inside the object What is an example: a vehicle and a truck is vehicle! Common features can be methods, attributes and associations.

Etiam rhoncus. Each class requires an accountNo attribute to identify the account on which the transaction will apply. Example: Now Suppose we override the superclass methods in sub class. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class.
