compiler error??

Question about the task

Archiver (part 4)

Java Multithreading, Level 7, Lesson 15

Resolved

This compiles for me, but will not compile on the server

Each command implies the execution of some action. Create a Command interface with an execute() method.
We'll create a separate class for each command. All of the command classes must implement (inherit) the Command interface.
The simplest command is EXIT, so let's start with that.

1. Create the command package
2. Declare the Command interface in it
3. Add a void execute() throws Exception method to the Command interface
4. Declare an ExitCommand class that implements the Command interface
5. Implement the execute() method in the ExitCommand class. It should use the ConsoleHelper class to display "Bye!"
6. At the very end of the Archiver class's main method, add code that creates an ExitCommand object and calls its execute() method
7. Check that it all works
Note that all the project files must be encoded in UTF-8. You can set the encoding in IntelliJ IDEA under Settings -> Editor -> File Encodings. Be sure that all three fields responsible for encoding are set to UTF-8.

Requirements:

The Command interface must be created in the command package.
Command must declare a void execute() throws Exception method.
Create an ExitCommand class in the command package. It must implement Command.
The execute method in the ExitCommand class must use ConsoleHelper to display "Bye!" on the console.
At the end of main method, you need to create an ExitCommand object and call its execute method.

package com.codegym.task.task31.task3110; import com.codegym.task.task31.task3110.command.ExitCommand; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.nio.file.Paths; public class Archiver { public static void main(String[] args) { try ( BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)) ) { String sPath; System.out.println("Enter (full) path for archive file:"); sPath = reader.readLine(); ZipFileManager zipFileManager = new ZipFileManager(Paths.get(sPath)); System.out.println("Enter (full) path for file to be zipped:"); sPath = reader.readLine(); zipFileManager.createZip(Paths.get(sPath)); new ExitCommand().execute(); } catch (Exception e) {} } }

As usual, this was my bad. In ExitCommand I imported the ConsoleHelper from task 3008 instead of this one in task 3110.
