java 怎么自动生成txt文件
HttpClient httpclient = new DefaultHttpClient(new ThreadSafeClientConnManager());

try {

//创建httpget.
String url[]={"http://www.sohu.com","http://www.baidu.com","http://www.sina.com"};


HttpGet httpget = null;
HttpResponse response = null;

for(int i = 0; i<url.length; i++){

httpget = new HttpGet(url[i]);

System.out.println("executing request " + httpget.getURI());

response = httpclient.execute(httpget);

System.out.println("响应状态：" + response.getStatusLine());
 
System.out.println("------------------------------------");
 
} 
}finally {
 
httpclient.getConnectionManager().shutdown();
}


把输出的内容自动生成一个txt文件，我是新手，最好有源码，谢谢了！！
