java怎么刪除一個(gè)帶內(nèi)容的目錄

可以使用Java的File類和遞歸來刪除帶有內(nèi)容的目錄。下面是一個(gè)示例代碼：

import java.io.File;

public class DeleteDirectoryExample {

    public static void main(String[] args) {
        File directory = new File("path/to/directory");
        deleteDirectory(directory);
    }

    public static void deleteDirectory(File directory) {
        if (directory.exists()) {
            File[] files = directory.listFiles();
            if (files != null) {
                for (File file : files) {
                    if (file.isDirectory()) {
                        deleteDirectory(file);
                    } else {
                        file.delete();
                    }
                }
            }
            directory.delete();
            System.out.println("Directory deleted: " + directory.getAbsolutePath());
        } else {
            System.out.println("Directory not found: " + directory.getAbsolutePath());
        }
    }
}

需要將"path/to/directory"替換為要?jiǎng)h除的目錄的實(shí)際路徑。該代碼會(huì)遞歸地刪除目錄中的所有文件和子目錄，直到目錄為空，然后再刪除該目錄本身。
