Java thread implements Runnable

In Java, a Thread is a class that represents a separate execution thread within a Java program. A Thread can be created by extending the Thread class and overriding the run method, or by implementing the Runnable interface and passing an instance of the implementing class to a Thread constructor.

Here's an example of how you can create a Thread by implementing the Runnable interface:

public class MyThread implements Runnable {
  public void run() {
    // code to be executed by the thread
  }
}

// create an instance of MyThread
MyThread myThread = new MyThread();

// create a new Thread and pass the instance of MyThread to the constructor
Thread thread = new Thread(myThread);

// start the thread
thread.start();

In this example, the MyThread class implements the Runnable interface and overrides the run method. An instance of MyThread is then passed to the Thread constructor, and the start method is called to start the thread.

The run method is the entry point for the thread, and it contains the code that will be executed by the thread when it is started.

It's important to note that the Thread class and the Runnable interface are part of the java.lang package and are included in the standard Java distribution. You do not need to import any additional libraries to use them.
