如何在Java文件路径中使用通配符 [英] How to use a Wildcard in Java filepath

问题描述

我想知道是否以及如何在Path定义中使用通配符. 我想更深入地使用一个文件夹并尝试使用*，但这不起作用.

i want to know if and how i could use a Wildcard in a Path definition. I want to go one folder deeper and tried using the * but that doesnt work.

我想访问随机文件夹中的文件.文件夹结构是这样的:

I want to get to files that are in random folders. Folderstructure is like this:

\test\orig\test_1\randomfoldername\test.zip
\test\orig\test_2\randomfoldername\test.zip
\test\orig\test_3\randomfoldername\test.zip

我尝试过的事情:

File input = new File(origin + folderNames.get(i) + "/*/test.zip");

File input = new File(origin + folderNames.get(i) + "/.../test.zip");

提前谢谢！

推荐答案

我认为不可能以这种方式使用通配符.我建议您对任务使用类似的方法:

I don't think that it's possible to use wildcard in such way. I propose you to use a way like this for your task:

    File orig = new File("\test\orig");
    File[] directories = orig.listFiles(new FileFilter() {
      public boolean accept(File pathname) {
        return pathname.isDirectory();
      }
    });
    ArrayList<File> files = new ArrayList<File>();
    for (File directory : directories) {
        File file = new File(directory, "test.zip");
        if (file.exists())
            files.add(file);
    }
    System.out.println(files.toString());
