Java thread

There are two ways to create a thread in Java - 1. By extending Thread class. You can create a new thread simply by extending your class from Thread and overriding it’s run() method. The run() method contains the code that is executed inside the new thread. Once a thread is created, you can start it by calling the start() method.

There are multiple states of the thread in a lifecycle as mentioned below: New Thread: When a new thread is created, it is in the new state. The thread has not yet started to run when the thread is in this state. When a thread lies in the new state, its code is yet to be run and hasn’t started to execute. A Thread is a very light-weighted process, or we can say the smallest part of the process that allows a program to operate more efficiently by running multiple tasks simultaneously. In order to perform complicated tasks in the background, we used the Thread concept in Java. All the tasks are executed without affecting the main program.

Java’s multithreading system is built upon the Thread class, its methods, and its companion interface, Runnable. To create a new thread, your program will either extend Thread or implement the Runnableinterface.
