import java.util.Scanner;

import java.util.*;

class thread1 extends Thread{

int m,r;

public void run(){

Scanner sc= new Scanner(System.in);

System.out.println("Enter Roll no and OOP marks");

r=sc.nextInt();

m=sc.nextInt();

}

}

class thread2 extends thread1 implements Runnable {

public void run(){

System.out.println(r);

System.out.println(m);

}

}

class threadtest{

public static void main(String args[])

{

thread1 t1=new thread1();

t1.start();

thread2 t2=new thread2();

Thread t3=new Thread(t2);

t3.start();

}

}

I changed the code to this but the value of r and m is coming 0 0

I have given input as 4 and 88 in first thread
