java 下载txt文件到本地

你可以使用以下代码将txt文件下载到本地：

import java.io.BufferedInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;

public class FileDownloader {

    public static void downloadFile(String fileUrl, String savePath) throws IOException {
        URL url = new URL(fileUrl);
        URLConnection connection = url.openConnection();
        connection.connect();

        InputStream inputStream = new BufferedInputStream(connection.getInputStream());
        FileOutputStream outputStream = new FileOutputStream(savePath);

        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, bytesRead);
        }

        outputStream.close();
        inputStream.close();
    }

    public static void main(String[] args) {
        String fileUrl = "https://example.com/file.txt";
        String savePath = "C:/path/to/save/file.txt";

        try {
            downloadFile(fileUrl, savePath);
            System.out.println("文件下载成功！");
        } catch (IOException e) {
            System.out.println("文件下载失败: " + e.getMessage());
        }
    }
}

请注意替换`fileUrl`和`savePath`为你实际的文件URL和保存路径。这段代码将会从指定的URL下载文件，并将其保存到本地。
