    It is a sin to use scriptlets in our age. Better this way:

    Lister.java

     package com.example; import java.io.IOException; import java.io.File; import java.nio.file.Files; import java.nio.file.Paths; import java.util.stream.Collectors; public class Lister { private String path; public Lister() {} public void setPath(String path) throws IOException { if (!new File(path).isDirectory()) throw IOException("Not a directory!"); this.path = path; } public String getPath() { return path; } public List<File> getFiles() throws IOException { return Files.walk(Paths.get(path)) .filter(Files::isRegularFile) .collect(Collectors.toList()); } }

    It is possible for Lister to complicate a little more, so that instead of a list of File objects, it returns a list of wrappers that beautifully show the size and modification date.

    • Thank you, everything is fine, it works. Only unfortunately, where it is necessary, jdk 1.7 costs (it will seem strange to you, but I can’t change it, because it doesn’t depend on me), so there is no walk method. - Pavel Govorkov
