代码在这里，自己看：

package test;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class TestURLReader {
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		BufferedWriter bw = null;
		try {
			int i=0;
				File f = new File("F:/test" + i + ".html");
				URL url = new URL("http://www.baidu.cn");
				BufferedReader buf = new BufferedReader(new InputStreamReader(
						url.openStream()));

				String str;
				String all = "";
				bw = new BufferedWriter(new FileWriter(f, false));

				while ((str = buf.readLine()) != null) {
					all += str;
				}
				bw.write(all.toString());
				bw.close();
			
		} catch (Exception e1) {
			e1.printStackTrace();
		} finally {
			try {
				bw.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
			System.exit(0);
		}
	}
}
