    In the example that you've given, why use abstract class, you can use interface instead

    1. when you don't define method tou can make it abstract.
    2. class need to be abstract if it has abstract method.
    3. when a class extend abstract class, we must make sure
    that we have define the abstract method.
    4. Human(abstract class, super class), extended by
    Man(concrete class, sub class)

    But this can be done by making writer, an interface as well. So when should we use abstract class instead of interface after java 8…?

    Hi, sir I want your help, when you click on integer you can view its source file(i.e. Integer.class), but while I am clicking on integer in my pc, I am not able to do so, and it is asking for add source file instead,
