나는 자바에 다음 링크에서 파일을 다운로드해야

[http://www.nseindia.com/content/historical/EQUITIES/2017/OCT/cm30OCT2017bhav.csv.zip][1]

나는 나 자신이 발견

WebClient webClient = new WebClient(); 
String accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; 
String agent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.83 Safari/537.1"; 
webClient.Headers.Add(HttpRequestHeader.Accept, accept); 
webClient.Headers.Add(HttpRequestHeader.UserAgent, agent); 
webClient.UseDefaultCredentials = true; 
webClient.DownloadFile(source, target);

C#으로 작성된 코드가 어떤 하나의 자바 상응하는 코드를 제안 할 수있다 해결책
