Question

1. First program:
   • Name of the program must be WritingToIO;
   • The program uses two variables named emplNum and salary;
   • The program must be able to accept values for each of the variables and save the information to a file called SalariesData.txt.
2. Second program:
   • Name of the program must be ReadingFromIO;
   • This program must ensure the information/ values can be retrieved from the file SalariesData.txt referred to in Step 1a above (i.e. the file where the employee salary data was written to).

Answer 1

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

class WritingToIO

{

public static void main(String[] args)

{

try

{ File myObj = new File("SalariesData.txt");

Scanner myReader = new Scanner(myObj);

while (myReader.hasNextLine())

{ int emplNum = myReader.nextInt();

System.out.println("enter the employee number");

int salary= myReader.nextInt();

System.out.println("enter the employee salary");

}

myReader.close();

} catch (FileNotFoundException e)

{ System.out.println("An error occurred.");

e.printStackTrace();

} } }
