java如何抓取网页呢？

实现思路:
    使用new URL中的openStream()读取流中的信息
	获取URL中的stream

package com.java265.other;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.net.URL;
public class Test16 {

	public static void main(String[] args) throws Exception {
		URL url = new URL("http://www.java265.com");
		BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));
		BufferedWriter writer = new BufferedWriter(new FileWriter("test.html"));
		String line;
		while ((line = reader.readLine()) != null) {
			System.out.println(line);
			writer.write(line);
			writer.newLine();
		}
		reader.close();
		writer.close();
	}
}
