How to list the files inside a JAR file?

Question

I have this code which reads all the files from a directory.

    File textFolder = new File(\"text_directory\");

    File [] texFiles = textFolder.listFiles         


        

Answer 1

Code that works for both IDE's and .jar files:

import java.io.*;
import java.net.*;
import java.nio.file.*;
import java.util.*;
import java.util.stream.*;

public class ResourceWalker {
    public static void main(String[] args) throws URISyntaxException, IOException {
        URI uri = ResourceWalker.class.getResource("/resources").toURI();
        Path myPath;
        if (uri.getScheme().equals("jar")) {
            FileSystem fileSystem = FileSystems.newFileSystem(uri, Collections.emptyMap());
            myPath = fileSystem.getPath("/resources");
        } else {
            myPath = Paths.get(uri);
        }
        Stream walk = Files.walk(myPath, 1);
        for (Iterator it = walk.iterator(); it.hasNext();){
            System.out.println(it.next());
        }
    }
}
