如果您不想使用 apache 库!您可以递归地执行此操作。
String directory = userprofile + File.separator + "Downloads" + File.separator + "Software_Tokens";
if (!directory.exists()) {
System.out.println("Directory does not exist.");
System.exit(0);
} else {
try {
delete(directory);
} catch (IOException e) {
e.printStackTrace();
System.exit(0);
}
}
System.out.println("Done");
}
public static void delete(File file)
throws IOException {
if (file.isDirectory()) {
//directory is empty, then delete it
if (file.list().length == 0) {
file.delete();
System.out.println("Directory is deleted : " + file.getAbsolutePath());
} else {
//list all the directory contents
String files[] = file.list();
for (String temp: files) {
//construct the file structure
File fileDelete = new File(file, temp);
//recursive delete
delete(fileDelete);
}
//check the directory again, if empty then delete it
if (file.list().length == 0) {
file.delete();
System.out.println("Directory is deleted : " + file.getAbsolutePath());
}
}
} else {
//if file, then delete it
file.delete();
System.out.println("File is deleted : " + file.getAbsolutePath());
}
