Java创建文件并将文件写入本地目录不起作用

File directory = new File("path/to/directory");
directory.mkdirs();

File file = new File("path/to/directory/filename.txt");

try {
    FileWriter writer = new FileWriter(file);
    writer.write("File content");
    writer.close();
} catch (IOException e) {
    e.printStackTrace();
}

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class FileCreationExample {
    public static void main(String[] args) {
        String directoryPath = "path/to/directory";
        String fileName = "filename.txt";
        String fileContent = "File content";

        File directory = new File(directoryPath);
        directory.mkdirs();

        File file = new File(directoryPath + "/" + fileName);

        try {
            FileWriter writer = new FileWriter(file);
            writer.write(fileContent);
            writer.close();
            System.out.println("File created and written successfully.");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
