请有人向我描述一下HTTP实体究竟是什么？

我正在阅读HTTPClient文档,但我真的不明白这意味着什么？

嘿大家我得到这个奇怪的错误,我无法弄清楚为什么？

package com.androidbook.services.httpget;

import java.io.BufferedReader; import java.io.IOException;
import java.io.InputStreamReader;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

import android.app.Activity;
import android.os.Bundle;

public class HttpGetDemo extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        BufferedReader in = null;
        try {
            HttpClient client = new DefaultHttpClient();
            HttpGet request = new HttpGet("http://code.google.com/android/");
            HttpResponse response = client.execute(request);
            in = new BufferedReader(
                    new InputStreamReader(
                        response.getEntity().getContent()));

            StringBuffer sb = new StringBuffer("");
            String line = ""; …

如何通过Java中的tcp发送arraylist？我需要发送一个整数的arraylist,从客户端到服务器,反之亦然.

Thanxx
