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
