Java-for循环中的删除文件不起作用

Question

我正在尝试在for循环中删除文件。

for(int i = 0; i < 3; i++) {

   String pathName = "test" + i + ".csv";
   boolean success = (new File(pathName)).delete();

}

仅删除第一个文件，不删除其他文件。

Answer 1

for(int i = 1; i <= 3; i++) {
    boolean success = (new File("C:\\Users\\Suppada-Aide\\Desktop\\test"+i+".txt")).delete();
    System.out.println(success);
}

Answer 2

public class Example {
    public static void main(String args[]) {
        File folder = new File("C:\\Users\\Desktop\\New Folder");
        deleteFiles(folder);
    }

    private static void deleteFiles(File folder) {
        for (File file : folder.listFiles()) {
            if (file.isDirectory()) {
                deleteFiles(file);
            }
            if (file.delete()) {
                System.out.println("File deleted");
            }

        }

    }

}

输出：

File deleted
File deleted
