C++ 和JAVA遞迴遍歷刪除目錄
JAVA:
import java.io.File;
public class DeleteDirectory { /** * 刪除空目錄 * @param dir 將要刪除的目錄路徑 */ private static void doDeleteEmptyDir(String dir) { boolean success = (new File(dir)).delete(); if (success) { System.out.println("Successfully deleted empty directory: " + dir); } else { System.out.println("Failed to delete empty directory: " + dir); } }
/** * 遞迴刪除目錄下的所有檔案及子目錄下所有檔案 * @param dir 將要刪除的檔案目錄 */ private static boolean deleteDir(File dir) { if (dir.isDirectory()) { String[] children = dir.list(); //遞迴刪除目錄中的子目錄下 for (int i=0; i<children.length; i++) { boolean success = deleteDir(new File(dir, children[i])); if (!success) { return false; } } } // 目錄此時為空，可以刪除 return dir.delete(); } /** *測試 */ public static void main(String[] args) { // doDeleteEmptyDir("D:\\jsoup"); String newDir2 = "D:\\jsoup"; boolean success = deleteDir(new File(newDir2)); if (success) { System.out.println("Successfully deleted populated directory: " + newDir2); } else { System.out.println("Failed to delete populated directory: " + newDir2); } } }
