ตัวอย่าง
ลบ directory ชื่อ "C:\\users\\nopphanan7\\Directory2" และ directory ย่อยที่อยู่ในนั้นด้วย.
package demo.directory;
import java.io.File;
import java.io.IOException;
public class DeleteDirectoryExample {
private static final String SRC_FOLDER = "C:\\users\\nopphanan7\\Directory2";
/**
* @param args
*/
public static void main(String[] args) {
File directory = new File(SRC_FOLDER);
// make sure directory exists
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());
}
}
}
ผลลัพธ์ที่ได้คือ
Directory is deleted : C:\users\nopphanan7\Directory2\Sub2\Sub-Sub2 Directory is deleted : C:\users\nopphanan7\Directory2\Sub2 Directory is deleted : C:\users\nopphanan7\Directory2 Done
