Java I/O - 如何从输入流复制到具有java.nio.file.Files的文件

import java.io.InputStream;
import java.net.URI;
import java.nio.file.FileSystems;
import java.nio.file.Files;
import java.nio.file.Path;

public class Main {

  public static void main(String[] args) throws Exception {
    Path newFile = FileSystems.getDefault().getPath("C:/h.html");
    URI url = URI.create("http://jdk7.java.net/");
    InputStream inputStream = url.toURL().openStream();
    Files.copy(inputStream, newFile);
    System.out.println("Site copied successfully!");

  }
}
