multiple inheritance, Google the "dreaded diamond". Java 8 adds default and static methods to interfaces which have traditionally been Java's answer to multiple inheritance. These bring it closer to C++ multiple inheritance, probably a good thing although I've yet to encounter it much in the ...
1. What is Inheritance in Java? In inheritance, a class extends another class to inherit all its non-private members, by default. This class is called the child class or subclass. The class from which the child class extends is called the parent class or superclass. In Java,extendskeyword...
Multi-Level inheritance is a type of inheritance in which one class is inherited by another class which is in turn inherited by the third class. The concept is depicted in the following diagram, Here, is a diagram that depicts a multilevel inheritance in which two single inheritances are joi...
This is achieved through the Builder class which allows you to specify various options. Once the options have been specified, build() is called to get an instance of the AeroMapper. Thus, the simplest usage is:AeroMapper mapper = new AeroMapper.Builder(client).build();...
If an abstract class lacks method implementations entirely, it’s advisable to consider using an interface. Java doesn’t support multiple-class inheritance. Subclasses of an abstract class in Java must implement all the abstract methods unless the subclass is also abstract. ...
In Java, abstraction is achieved byinterfacesandabstract classes. Interfaces allow you to abstract the implementation completely, while abstract classes allow partial abstraction as well. Data abstractionspans from creating simple data objects to complex collection implementations such asHashMaporHashSet. ...

The functional interfaces are a different story and they are proven to be very helpful add-on to the language. Basically, the functional interface is the interface with just a single abstract method declared in it. The Runnable interface from Java standard library is a good example of this con...
