如何从Java读取文件夹中的所有文件？

public void listFilesForFolder(final File folder) {    for (final File fileEntry : folder.listFiles()) {        if (fileEntry.isDirectory()) { listFilesForFolder(fileEntry);        } else { System.out.println(fileEntry.getName());        }    }}final File folder = new File("/home/you/Desktop");listFilesForFolder(folder);

Java 8提供了Files.walk API。

try (Stream<Path> paths = Files.walk(Paths.get("/home/you/Desktop"))) {    paths        .filter(Files::isRegularFile)        .forEach(System.out::println);}
