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:...
* Steps to use * multiple threads in Java : * 1. Implement Runnable interface to put the code * you want to run in separate thread. * 2. Create an Instance of Thread class by * passing an instance of Runnable you just created. ...
