Extends in Java is used for class inheritance, allowing a class to inherit properties from another class. Implements in Java is used by a class to adhere to an interface, defining specific methods.
An interface is a way of describing what classes should do, without specifying how they should do it. A class can implement more than one interface. In Java, an interface is not a class but a set of requirements for the class that we want to conform to t
Any interface can be functional interface, not merely those that come with Java. To declare your intention that an interface is functional, use the@FunctionalInterfaceannotation. Although not necessary, it will cause a compilation error if your interface does not satisfy the requirements (ie. one ...
you should implement theRunnableinterface and not create the subclass of theThreadclass itself. However, if you would like to leverage the functionality of theThreadclass and be able to control the life cycle of your thread, then extending theThreadclass is the ...

So by making our programs use ‘has-a’ relationship, what we are doing here is that we make our program use an instance of a class directly instead of ‘extending’ it from another class as we do in case of inheritance. The below diagram depicts both ‘is-a’ and ‘has-a’ relation...

In Java, a class can be marked as final, which means that it cannot be subclassed. This can be useful in a number of situations:
