Generate Random 10,000 numbers and store as 100*100 array in csv file.

try

        {

        Random r = new Random();

        //System.out.println("Numbers are");

      File file = new File("D:/p2.csv");

     

      FileWriter writer = new FileWriter(file);

    

      System.out.println("start");

        for(int i=1;i<=100;i++)

        {

            for(int j=1;j<=100;j++)

            {

                int value;

                value=r.nextInt(10000);

               writer.append(Integer.toString(value)+" ");                

            }

            writer.append('\n');

            writer.flush();

        }

        writer.close();
