在Java程式中,如何如何刪除一個目錄?
以下範例演示如何使用File
類的dir.isDirectory()
,dir.list()
和deleteDir()
方法來刪除其檔案和子目錄後,再刪除該目錄。
package com.yiibai;
import java.io.File;
public class DeleteDirectory {
public static void main(String[] argv) throws Exception {
String deldir = "F:\\worksp\\javaexamples\\java_directories\\dir1";
deleteDir(new File(deldir));
}
public static boolean deleteDir(File dir) {
if (dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
}
System.out.println("The directory is deleted.");
return dir.delete();
}
}
執行上面範例程式碼,得到以下結果 -
The directory is deleted.
The directory is deleted.
The directory is deleted.
註:由於dir1目錄中有兩個目錄,所以上面會多列印兩條資訊。
