what is a thread 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: create thread java

class RunnableObject implements Runnable {
   private Thread t;
   private String threadName;
   
   RunnableObject( String name) {
      System.out.println("Creating " +  threadName );
      threadName = name;
      t = new Thread (this, threadName);
   }
   
   public void run() {
      System.out.println("Running " +  threadName );
   }
   
   public void start () {
      System.out.println("Starting " +  threadName );
      t.start ();
   }
}

public class TestThread {

   public static void main(String args[]) {
      RunnableObject R1 = new RunnableObject( "Thread-1");
      R1.start();
   }   
}
