Java Threads

Threads help a software to work more effectively by allowing it to do numerous tasks at once.

Threads allow complex activities to be completed in the background without interrupting the main programme.

Creating a Thread

A thread could be made in two ✌ ways.

1. It's possible to create one by extending the Thread class and overriding the run() method.

2. Another way to create a thread is to implement the Runnable interface.

Running Threads

1. Extend Example : 

     public class Main extends Thread {
       public static void main(String[] args) {
         Main thread = new Main();
         thread.start();
         System.out.println("This code is outside of the thread");
       }
       public void run() {
         System.out.println("This code is running in a thread");
       }
     }
   

2. Implement Example : 

   public class Main implements Runnable {
     public static void main(String[] args) {
       Main obj = new Main();
       Thread thread = new Thread(obj);
       thread.start();
       System.out.println("This code is outside of the thread");
     }
     public void run() {
       System.out.println("This code is running in a thread");
     }
   }

Threads: The Differences Between "Extending" and "Implementing"👯

      The main difference is that a class that extends the Thread class cannot

extend any other class, whereas a class that implements the Runnable

interface can extend from any other class, such as: class MyClass extends

OtherClass implements Runnable.
