how to pass data as an arguments between two java classes using node js

i have two java classes , and i want to take the output of the first java class ,pass this data to Node Js then, finally this data must move from Node Js to the other Java class as arguments

this the first java class

public static void main(String[] args) {
        Random randomGenerator = new Random();
        String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

        long timestamp = System.currentTimeMillis() / 1000;
        for (int idx = 1; idx <= 10; ++idx) {
            int randomInt = randomGenerator.nextInt(100);
            System.out.println("Generated : \t" + randomInt + "\t time:\t" + timestamp);
            //System.out.println("Generated : \t" + randomInt + "\t time:\t" + timeStamp);

        }

    }

then this is the second one

String msg = args[]

producer.send(new KeyedMessage("topic",msg));
