[Util] Download Utility

Hello guys,

I made a simple download utility that you can use in your plugin, but I shall only use it for private plugins because I don't think that your plugin will get accepted if you can download a file with it.

You can use my utility like this:

Code:java

DownloadUtil util = new DownloadUtil(this, getDataFolder(), "[url]http://dev.bukkit.org/media/files/739/931/worldedit-5.5.8.jar[/url]");
 
        try {
            util.downloadFile(new File("test.jar"));
        } catch (IOException e) {
            e.printStackTrace();
        }

This is the utility class:

Code:java

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URL;
import java.nio.channels.Channels;
import java.nio.channels.ReadableByteChannel;
 
import com.github.sebasju1234.resources.ResourcePlugin;
 
public class DownloadUtil {
 
    private ResourcePlugin plugin;
    private File directory;
    private String url;
 
    /**
    * @param instance
    * @param directory
    * @param url
    */
    public DownloadUtil(ResourcePlugin instance, File directory, String url) {
        setPlugin(instance);
        setDirectory(directory);
        setUrl(url);
 
        checkFiles();
    }
 
    /**
    * @return
    */
    private ResourcePlugin getPlugin() {
        return plugin;
    }
 
    /**
    * @param plugin
    */
    private void setPlugin(ResourcePlugin plugin) {
        this.plugin = plugin;
    }
 
    /**
    * @return
    */
    private File getDirectory() {
        return directory;
    }
 
    /**
    * @param directory
    */
    private void setDirectory(File directory) {
        this.directory = directory;
    }
 
    /**
    * @return
    */
    private String getUrl() {
        return url;
    }
 
    /**
    * @param url
    */
    private void setUrl(String url) {
        this.url = url;
    }
 
    private void checkFiles() {
        if (getDirectory().exists()) {
            getDirectory().mkdirs();
        }
    }
 
    /**
    * @param path
    * @throws IOException
    */
    public void downloadFile(File path) throws IOException {
        if(!(path.exists())) {
            URL downloadUrl = new URL(getUrl());
            ReadableByteChannel readableByteChannel = Channels.newChannel(downloadUrl.openStream());
            FileOutputStream fileOutputStream = new FileOutputStream(path);
            fileOutputStream.getChannel().transferFrom(readableByteChannel, 0, Long.MAX_VALUE);
 
            plugin.getLogger().info("[DOWNLOAD] File has been download. (" + path.toString() + ")");
        }
    }
 
}

You have to change ResourcePlugin to your plugin instance. Tips and suggestions are welcome.
