java代码打出来以后怎么发给别人玩? 只有自己在Console里运行着玩
做swing的 界面，打成相应的.jar文件，发给别人，人家收到只要安装虚拟机应该可以双击运行了。

Q1: 用java写一个邮件发送代码
public boolean mainto()
{
boolean flag = true;
//建立邮件会话
Properties pro = new Properties();
pro.put("mail.smtp.host","smtp.qq.com");//存储发送邮件的服务器
pro.put("mail.smtp.auth","true"); //通过服务器验证
Session s =Session.getInstance(pro); //根据属性新建一个邮件会话
//s.setDebug(true);
//由邮件会话新建一个消息对象
MimeMessage message = new MimeMessage(s);
//设置邮件
InternetAddress fromAddr = null;
InternetAddress toAddr = null;
try
{
fromAddr = new InternetAddress(451144426+"@qq.com"); //邮件发送地址
message.setFrom(fromAddr); //设置发送地址
toAddr = new InternetAddress("12345367@qq.com"); //邮件接收地址
message.setRecipient(Message.RecipientType.TO, toAddr); //设置接收地址
message.setSubject(title); //设置邮件标题
message.setText(content); //设置邮件正文
message.setSentDate(new Date()); //设置邮件日期
message.saveChanges(); //保存邮件更改信息
Transport transport = s.getTransport("smtp");
transport.connect("smtp.qq.com", "451144426", "密码"); //服务器地址，邮箱账号，邮箱密码
transport.sendMessage(message, message.getAllRecipients()); //发送邮件
transport.close();//关闭
}
catch (Exception e)
{
e.printStackTrace();
flag = false;//发送失败
}
return flag;
}
这是一个javaMail的邮件发送代码，需要一个mail.jar
Q2: java一个简单的发送接收问题
接收端（服务端）中的socket要实时处于监听状态，即要设置一个死循环。
例如：
while(1){
//.....
}
当接收到一个客户端的消息，再为其开辟新的进程进行数据处理。
我也只是说个大概，具体建议网络上百度一下socket通信方法，看看人家服务器端是怎么写的。

Q4: java代码怎样运行出来？
步骤：
1、在cmd中切换到编写Java怎么发代码的代码所保存Java怎么发代码的目录下；
2、在cmd中输入javac然后点空格，再点击文件名和包括后缀名确定后，在存放编写代码的文件下会生成一个class的字节码文件；
3、在cmd中输入java然后点空格，输入第二步中生成的字节码的文件名，不需要后缀名，点击确定即可运行代码。
代码就是程序员用开发工具所支持的语言写出来的源文件，是一组由字符、符号或信号码元以离散形式表示信息的明确的规则体系。计算机代码称为源代码，是相对目标代码和可执行代码而言的。 源代码就是用汇编语言和高级语言写出来的地代码，目标代码是指源代码经过编译程序产生的能被cpu直接识别二进制代码。
