list - Detect multiple connected devices in Java -

-

I want to write a Java code that will meet the following requirements:

  2. List all devices connected to the laptop
  3. Allow users to choose which device should be used by the java program

For example, when there are 2 USB devices, the Java program will detect them and then convert them to (e.g. F: \, G :) Will be listed. After this, users can choose which device to use. What is the way to do this?

I found that this website is useful that my thumbnail is connected, however, it is not able to detect more than one device.

detect.java 

  Find public squares {public string USBDetect () {string drive litter = ""; FileSystemView fsv = FileSystemView.getFileSystemView (); File [f] = file. List root (); For (int i = 0; i  ("Removable"). type. )) {//log.info ("Detected PEN Drive:" + drive + "-" + displayName); Drive litter = drive; break; }} / * If (driveLetter.equals ("")) {System.out.println ("Not Found!"); } Else {System.out.println (drive liter); } * / / // system. Out.printlean (david letter); Return drive litter; }}

list. Java 

  public category list {public static zero main (string [] args) {file [units} = file.listRoots (); (File unit: units) {System.out.println (unit.getAbsolutePath ()); }}}

This code helps to detect more than 1 removable drive, but it also lists local drives. I believe that I find.java Should be included in some parts so that it can only detect removable drives. 2 and 3. As I have not tried so far because I do not know how to start, because I have not found any relevant website for reference. I hope you can provide me any useful website or code which can meet the requirements above. Sorry I'm new to Java 

  import java.io.file; Import javax.swing.filechooser.FileSystemView; Detects Public Square {Public Stable Zero Main (String [] Args) {Test Test = New Detect (); Test.USBDetect (); } Public Zero USBDetect () {String Drive Litter = ""; FileSystemView fsv = FileSystemView.getFileSystemView (); File [f] = file. List root (); For (int i = 0; i  ("Removable"). type. )) {//log.info ("Detected PEN Drive:" + drive + "-" + displayName); Drive litter = drive; Println (driveletter); }} / * If (driveLetter.equals ("")) {System.out.println ("Not Found!"); } Else {System.out.println (drive liter); } * / / // system. Out.printlean (david letter); }}

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
