Answer 1

thanks for the question, here is the code . Please update the below two lines which points to the input file that needs to be read and the location of the output file base don the location in your computer

    private static final String INPUT_FILE = "D:\\artist.txt";
    private static final String OUTPUT_FILE = "D:\\CAPSTEXT.txt";

import java.io.*;
import java.util.Scanner;
import java.util.ArrayList;

public class Programs {


    private static final String INPUT_FILE = "D:\\artist.txt";
    private static final String OUTPUT_FILE = "D:\\CAPSTEXT.txt";

    public static void main(String[] args) {

        ArrayList<String> fileLines = new ArrayList<>();

        // the below block of code reads from the input file into the ArrayList
        // coverts each line to upper case and add them to the arraylist
        try {
            Scanner scanner = new Scanner(new File(INPUT_FILE));
            while (scanner.hasNext()) {
                fileLines.add(scanner.nextLine().toUpperCase());
          }

            scanner.close();
        } catch (FileNotFoundException e) {
            System.out.println("Unable to read from file : " + INPUT_FILE);
            System.exit(1);
        }
        // the above block of code reads from the input file into the ArrayList


        // the below block of code takes each line from the array list and writes them
        // to the output file
        try {
            PrintWriter writer = new PrintWriter(new FileWriter(OUTPUT_FILE));
            for (String line : fileLines) {
                writer.write(line);
                writer.write("\r\n"); // add new line character to the end
            }
            writer.flush();
            System.out.println("File created successfully!");

        } catch (IOException e) {
            System.out.println("Unable to write data to file: " + OUTPUT_FILE);
        }

        // the above block of code takes each line from the array list and writes them
        // to the output file
