以下实例演示了使用 File 类的 ofdir.isDirectory(), dir.list() 和 deleteDir() 方法在一个个删除文件后删除目录 ：
Main.java 文件
import java.io.File;
public class Main {
public static void main(String[] argv) throws Exception {
// 删除当前目录下的 test 目录
deleteDir(new File("./test"));
}
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;
}
}
}
if(dir.delete()) {
System.out.println("目录已被删除！");
return true;
} else {
System.out.println("目录删除失败！");
return false;
}
}
}
以上代码运行输出结果为：
目录已被删除！
