 Thread in Java language

In this tutorial, we will discuss Thread and Multithreading programming in the Java programming language.

What's Thread in Java?

Java provides support for multithreaded programming. A multithreaded java program contains two or more parts. Each part is called a thread. So, Multithreading is a specialized form of multitasking.

 Methods that help manage threads:

• start() - Calling its run method.

• run() -  Entry point for the thread.

Creating a Thread:

There are two types of methods to create a thread.

• Extends Thread class.

• Implements Runnable interface.

Extends Thread Class:

 import java.io.*;
 public class thread extends Thread{    
    public static void main(String[] args){
        thread T = new thread();
        T.start();
        System.out.println("In Main Method");
    }
    public void run(){
        System.out.println("In Run Method");
    }
 }

Output:

In Main Method

In Run Method

Implements Runnable Interface:

 import java.io.*;
 public class thread implements Thread{    
    public static void main(String[] args){
        thread T = new thread();
        Thread t = new Thread(T);
        t.start();
        System.out.println("In Main Method");
    }
    public void run(){
        System.out.println("In Run Method");
    }
 }

Output:

In Main Method

In Run Method
