Explain the difference between single inheritance and multiple inheritance in Java.解释一下Java中单一继承和多重继承的区别。 相关知识点: 试题来源: 解析 Java类只支持单一继承(一个子类只能继承一个父类),但通过接口可以实现多重继承(一个类可实现多个接口)。 在Java中,单一继承指一个类只能直接继承自一个...
, and final . we can achieve abstraction, multiple inheritances, and loose coupling in java using interfaces. abstraction: the interface reveals only the essential information needed to invoke the method, whereas the complexities of the implementation remain concealed. multiple inheritance: a class can...

interface, that class needs to implement all the methods defined in the interface, but when a subclass extends a super class, it may or may not override the methods included in the parent class. Finally, another key difference between Implements and Extends is that, a class can implement ...
Class extension (full-blown inheritance -- interface and implementation) is like strapping on a backpack in which your instances carry around not only their own instance variables and everything they refer to in a graph of objects, but also those of all their superclasses. If you don't own...
Interfaces are absolutelyabstractand cannot be instantiated; A Java abstract class also cannot be instantiated but can be invoked if amain()method exists. 5. When to Use? Always remember that choice between the interface or abstract class is not either/or scenario, where choosing anyone without ...
Abstract classes and inheritance With an interface on the other hand, the relationship between the interface itself and the class implementing the interface is not necessarily strong. For example, if we have a class called "House", that class could also implement an interface called "AirConditionin...
This is the most fundamental reason why interface is used in .NET projects. It helps application code to stay decoupled and thus easier to refactor, change, and redeploy so that you can easily work on the maintanence phase. The other famous reason is to have multiple inheritance. Abstract ...
and define methods that every subclass should implement and then if there are some methods that only certain subclass should implement, we can extend the base interface and create a new interface with those methods. The subclasses will have the option to chose between the base interface or the ...
