thread in java

In Java, a Thread is a class that represents a separate execution thread within a Java program. A Thread can be created and started by calling the Thread class's start method, which causes the run method of the Thread to be executed in a separate thread of control.

Here's an example of how you can create and start a Thread in Java:

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

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

// start the thread
myThread.start();

In this example, the MyThread class extends the Thread class and overrides the run method. An instance of MyThread is then created 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 is part of the java.lang package and is included in the standard Java distribution. You do not need to import any additional libraries to use it.

You can also create a Thread by implementing the Runnable interface and passing an instance of the implementing class to a Thread constructor. This is often done when you want to create a Thread but do not want to extend the Thread class, as a Java class can only extend one superclass.
