如何在java中的zip文件中访问文件和文件夹列表？

Question

I am trying to retrieve a list of folders and files that are in a zipped file but it returns null

File zipDir = new File(strFilePath+".zip");

String[] dirList = zipDir.list();

Can anyone please tell me what mistake I am making here or is there any other alternative?

Answer 1

You need to use the ZipFile class, eg like

ZipFile zipFile = new ZipFile(strFilePath + ".zip");
Enumeration<? extends ZipEntry> entries = zipFile.entries();
while(entries.hasMoreElements()) {
    ZipEntry entry = entries.nextElement();
    System.err.println(entry.getName());
}
