Abstract Class vs. Interface

An abstract class allows you to create functionality that subclasses can implement or override. An interface only allows you to define functionality, not implement it. And whereas a class can extend only one abstract class, it can take advantage of multiple interfaces.

Daemon Threads

When Daemon Threads are useful

In a big project, some threads are there to do some background task such as sending data, performing periodic garbage collection etc. It can be done by non-daemon thread. But if non-daemon thread is used, the main thread has to keep track of them manually. However, using daemon thread the main thread can completely forget about this task and this task will either complete or be killed when main thread exits.
