In Java, the abstraction is a process of hiding the implementation details and showing only functionality to the user. The "abstract" keyword is used to declare an abstract class and an abstract class can have both abstract and non-abstract methods....
Abstract class in Java is similar to interface except that it can contain default method implementation. An abstract class can have an abstract method without body and it can have methods with implementation also. Here is a simple example of an Abstract Class in Java. package com.journaldev.desi...
The subclass can inherit and use the concrete methods of the abstract class. Objects of the subclass can be instantiated and used in the program. By effectively utilizing abstract classes in Java, developers can design organized, extensible code structures that streamline development and promote adhere...
