(Solved Homework): Please need help in java (please don't use Path, the instructor suggest to use readByte)…

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class Enigma {

    public static void main(String[] args) {
        File inputFile = new File(args[0]);
        File outputFile = new File(args[1]);

        FileInputStream fileInputStream;
        FileOutputStream fileOutputStream;
        byte[] bFile = new byte[(int) inputFile.length()];
        try
        {
            //convert file into array of bytes
            fileInputStream = new FileInputStream(inputFile);
            fileOutputStream = new FileOutputStream(outputFile);

            fileInputStream.read(bFile);
            fileInputStream.close();

            //write byte + 5 for each byte
            for (int i = 0; i < bFile.length; i++)
            {
                fileOutputStream.write(bFile[i] + 5);
            }
            fileOutputStream.close();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
