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
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.
• By extending a java .lang. Thread class and override its run () method • By implementing the Runnable interface and implementing its run() method Now the question arises which of the two thread creating techniques one should use. The first technique can only be used for classes that...
In Java, creating a thread is accomplished by implementing an interface and extending a class. Everythread in Javais created and controlled by thejava.lang.Thread class. A single-threaded application has only one Java thread and can handle only one task at a time. To handle multiple tasks in...
In Java 8 afunctional interfaceis defined as an interface with exactly one abstract method. This even applies to interfaces that were created with previous versions of Java. Java 8 comes with several new functional interfaces in the package,java.util.function. ...
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. ...

To prevent others from extending your class and potentially introducing incompatible changes. This can be especially useful if your class has a well-defined interface that you want to maintain. To ensure that your class can be used safely in a multithreaded environment. If a class is not final...
and lives and dies on the heap. One Thread is created by per stack call where it gets Id, process number, methods, and other parameters. In java, creating a thread is done by implementing an interface and extending a class. A thread with higher priority is executed first, followed by lo...
