What is the use of input stream reader in java or blue j?

Answer 1

In InputStreamReader Method , the user can input the values in terminal window and can get the output in the terminal windows as well.

Example : 

import java.io.*;

class InputStreamReader

{

static void test()throws IOException

{

InputStreamReader isr = new InputStreamReader(System.in);

BufferedReader br = new BufferedReader(isr);

System.out.println(“Enter the first value “);

int fstval = Integer.parseInt(br.readLine());

System.out.println(“Enter the second value “);

 

int sndval = Integer.parseInt(br.readLine());

int sum = fstval+sndval;

int product = fstval-sndval;

System.out.println(“The sum of “+fstval+” and“+sndval+” is “+sum);

System.out.println(“The product of “+fstval+” and “+sndval+” is “+product);

}

}
