Save URL to file with Java 7

Details: Published: 29 February 2012

Here's how to save a url to file using the java.nio.file.Files class. This enables us to copy the InputStream from the URLin a simple way to a file. The source is HERE

import java.io.File;
import java.io.IOException;
import java.io.InputStream;

import java.net.URL;

import java.nio.file.Files;
import java.nio.file.StandardCopyOption;

public class UrlSaver {
    public static void main(String[] args) throws IOException {
        // Save url to file url.html in temp directory
        String html = new File(System.getProperty("java.io.tmpdir"), "url.html").getAbsolutePath();
        UrlSaver.copyStreamToFile(new URL(args[0]).openStream(), html);
    }

    public static void copyStreamToFile(InputStream source, String target) {
        try {
            Files.copy(source, new File(target).toPath(),
                StandardCopyOption.REPLACE_EXISTING);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
