1.2. By ImplementingRunnableInterface Implementing theRunnableinterface is considered a better approach because, in this way, the thread class can extend any other class. Remember, in Java, a class can extend only one class but implement multiple interfaces. classSubTaskWithRunnableimplementsRunnable{pu...
you need to first define the task which will be executed by those threads. In order to create those tasks, you can either use theRunnableorCallableinterface. If you are just learning
First, create a class that properly implements the ‘Runnable’ interface. Remember, this interface has only one function that the class must implement: ‘run()’. The ‘run()’ method implementation must include code the user wants to run on a different thread. After that, create an instanc...

Since lambda expression in Java is SAM type (Single Abstract Method) you can use it with any interface which got just one method like Comparator, Comparable, Runnable, Callable, ActionListener, and so on.Earlier we used to use the Anonymous class to implement these one method interfaces, ...
Interfaces force the implementing classes to implement a certain behavior. To implement an interface, a class must use implements keyword. public class WorkerThread implements Runnable { //... } In Java, we can implement more than one interface. In this case, the class must implement all the...
It will implement Runnable interface. public class OddEvenRunnable implements Runnable{ public int PRINT_NUMBERS_UPTO=10; static int number=1; int remainder; static Object lock=new Object(); OddEvenRunnable(int remainder) { this.remainder=remainder; } @Override public void run() { while (number...
notify()to signal waiting threads that new work has arrived. The following example shows a simple work queue which is queue ofRunnableobjects. This is a common convention for schedulers and work queues, although there is no particular need imposed by the Thread API to use theRunnableinterface....
In the following code, first we will implement the run() method from a Runnable functional interface. Then, we will create a Thread and use the run() method we’ve just implemented within the Thread. Finally, we will start the Thread to execute asynchronously:...
