socket问题，本机作为客户端，断网后，怎么不抛socket异常啊？
public   static   void   main(String[]   args)
{

InetAddress   address   =   null;
Socket   socket   =   null;
try
{
address   =   InetAddress.getByName( "202.102.15.115 ");
socket   =   new   Socket(address,   8080);

if   (socket.isConnected())
{
System.out.println( "ok! ");
}
else
{
System.out.println( "fail! ");
}
}
catch   (Exception   e)
{
e.printStackTrace();
System.out.println( "fail! ");
}
finally
{
if   (null   !=   socket)
{
try
{
socket.close();
}
catch   (Exception   e)
{
e.printStackTrace();
}

}

}

}

------解决方案--------------------
把你的catch里不写输出，不就不抛异常了？不过这样只是骗客户而已，断开连接必然出现提示，只是你捕获还是不捕获的问题
