Your task is to improve a multi-threaded program that frequently writes small entries to a shared file by introducing a layer that merges in memory before writing to file to reduce the number of expensive I/O operations. Imagine a program which writes to file small log entries very frequently. The program is multithreaded and each thread writes log entries to a common log file. To simplify implementation, each thread just writes log individually with blocking I/O interface. Even though threads write to the shared file concurrently without any locking, this is correct because the OS guarantees the atomicity of individual write() operation

The program is given below

import java.io.IOException;

import java.util.InputMismatchException;

import java.util.Scanner;

public class Add {

public static void main(String[] args)throws IOException

{

   int a=0, b=0, sum;

   Scanner sc=new Scanner(System.in);

   System.out.println("Enter the numbers to be summed");

   try{

       a=sc.nextInt();

       sc.nextLine();

       b=sc.nextInt();

   }

   catch(InputMismatchException e){

       System.out.println("Please enter an Integer number");

       e.printStackTrace();}

   catch(Exception e){System.out.println(e);}

   sum=a+b;

   System.out.println(sum);

   sc.close();

}

}

iphones are still better

i'm pretty sure data is stored in a form
