Question about this Task

Question about the task

Your own implementation

Java Collections, Level 1, Lesson 4

Resolved

I wonder how can I complete this task without import java.nio.file.Path;?

Implement the following methods:
1. readBytes - must return all of the bytes in the fileName file.
2. readLines - must return all of the lines in the fileName file. Use the default encoding.
3. writeBytes - must write a byte array to the fileName file.
4. copy - must copy the resourceFileName file to the destinationFileName file.

HERE'S THE MOST IMPORTANT CONDITION:
You can't add any other imports!

Requirements:

The Solution class's imports can't be changed.
The readBytes method must return all the bytes in the fileName file.
The readLines method must return all the lines in the fileName file using the default encoding.
The writeBytes method must write a byte array to the fileName file.
The copy method must copy the resourceFileName file to the destinationFileName file.

package com.codegym.task.task31.task3103; import java.io.IOException; import java.nio.charset.Charset; import java.nio.file.Files; import java.nio.file.Paths; import java.nio.file.Path; import java.util.List; /* Your own implementation */ public class Solution { public static byte[] readBytes(String filename) throws IOException { Path path = Paths.get(filename); byte[] bytes = Files.readAllBytes(path); return bytes; } public static List<String> readLines(String filename) throws IOException { Path path = Paths.get(filename); List<String> list = Files.readAllLines(path); return list; } public static void writeBytes(String filename, byte[] bytes) throws IOException { Path path = Paths.get(filename); Files.write(path, bytes); } public static void copy(String resourceFilename, String destinationFilename) throws IOException { Path resource = Paths.get(resourceFilename); Path destination = Paths.get(destinationFilename); Files.copy(resource, destination); } }

solution

well, I fixed my mistake with following code

public static byte[] readBytes(String filename) throws IOException {
        byte[] bytes = Files.readAllBytes(Paths.get(filename));
        return bytes;
    }
