Answer 1

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

public class Main {

public static void main(String[] args) {

try (FileReader reader = new FileReader("salaries.txt");

BufferedReader br = new BufferedReader(reader)) {

String line;

while ((line = br.readLine()) != null) {

System.out.println(line);

String[] inputs = line.split(" ");

String lastName = inputs[0];

String firstName = inputs[1];

double salary = Double.parseDouble(inputs[2]);

double raise = Double.parseDouble(inputs[3]);

double newSalary = (1 + raise/100) * salary;

System.out.println(String.format("%c. %s %.2f\n", Character.toUpperCase(firstName.charAt(0)), lastName, newSalary));

try (FileWriter writer = new FileWriter("output.txt", true);

BufferedWriter bw = new BufferedWriter(writer)) {

bw.write(String.format("%c. %s %.2f\n", Character.toUpperCase(firstName.charAt(0)), lastName, newSalary));

} catch (IOException e) {

System.err.format("IOException: %s%n", e);

}

}

} catch (IOException e) {

System.err.format("error occurred while opening the file", e);

}

}
