threading in java code example

Example 1: java thread

public class ClassName extends Thread{
  public void run(){
    super.run();
    //Your Code
  }
}

public class Main{
  public static void main(String[] args){
    ClassName thread = new ClassName();
    thread.start();
  }
}

Example 2: java thread

public static void main(String[] args {
   ...
   Thread t1= new Thread(...);
   t1.start();
   ...
}

Example 3: creating thread in java example

class Multi3 implements Runnable{  
public void run(){  
System.out.println("thread is running...");  
}  
  
public static void main(String args[]){  
Multi3 m1=new Multi3();  
Thread t1 =new Thread(m1);  
t1.start();  
 }  
}

Example 4: threads java

// Copy and test
// They run simultaneously

public static void main(String[] args) {
  		// How to create a thread
        Thread thread = new Thread(new Runnable() {
            @Override
			// Loop running in thread
            public void run() {
                for (int i = 0; i < 20; i++) {
                    System.out.println("Printing plus " + i + " in a worker thread.");
                    try {
                        Thread.sleep(1000);
                    } catch(Exception e) {
                        e.printStackTrace();
                    }
                }
            }
        });
        thread.start();
  		// Loop running in main thread 
        for (int j = 0; j < 20 ; j++) {
            System.out.println("Printing plus " + j + " in a main thread.");
            try {
                Thread.sleep(900);
            } catch(Exception e) {
                e.printStackTrace();
            }
        }
        }

Example 5: multithreading in java

class Count implements Runnable
{
   Thread mythread ;
   Count()
   { 
      mythread = new Thread(this, "my runnable thread");
      System.out.println("my thread created" + mythread);
      mythread.start();
   }
   public void run()
   {
      try
      {
        for (int i=0 ;i<10;i++)
        {
          System.out.println("Printing the count " + i);
          Thread.sleep(1000);
        }
     }
     catch(InterruptedException e)
     {
        System.out.println("my thread interrupted");
     }
     System.out.println("mythread run is over" );
   }
}
class RunnableExample
{
    public static void main(String args[])
    {
       Count cnt = new Count();
       try
       {
          while(cnt.mythread.isAlive())
          {
            System.out.println("Main thread will be alive till the child thread is live"); 
            Thread.sleep(1500);
          }
       }
       catch(InterruptedException e)
       {
          System.out.println("Main thread interrupted");
       }
       System.out.println("Main thread run is over" );
    }
}

Example 6: multithreading in java simple example

class MultithreadingDemo extends Thread{  
  public void run(){  
    System.out.println("My thread is in running state.");  
  }   
  public static void main(String args[]){  
     MultithreadingDemo obj=new MultithreadingDemo();   
     obj.start();  
  }  
}
