java下载zip文件

你可以使用Java中的URLConnection类来下载zip文件。以下是一段示例代码：

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 DownloadZipFile {
    public static void main(String[] args) throws IOException {
        String url = "http://example.com/example.zip";
        String saveFilePath = "example.zip";

        URLConnection conn = new URL(url).openConnection();
        conn.connect();

        InputStream inputStream = conn.getInputStream();
        BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
        FileOutputStream fileOutputStream = new FileOutputStream(saveFilePath);

        byte[] data = new byte[1024];
        int count;
        while ((count = bufferedInputStream.read(data, 0, 1024)) != -1) {
            fileOutputStream.write(data, 0, count);
        }

        fileOutputStream.flush();
        fileOutputStream.close();
        bufferedInputStream.close();
        inputStream.close();

        System.out.println("Zip file downloaded successfully.");
    }
}

你只需要将`url`变量替换为要下载的zip文件的URL，将`saveFilePath`变量替换为要保存zip文件的本地路径和文件名，然后运行这段代码即可下载zip文件。
