以上代码显示Exception in thread "main" java.net.SocketException: Connection reset

这个错误信息是Java中的一个异常，称为SocketException。它表示在尝试建立或使用网络连接时发生了问题。具体来说，"Connection reset"表示连接被对方重置，即连接的一方突然关闭了连接，导致另一方无法继续通信。

这种情况通常发生在以下几种情况下：
1. 服务器端意外关闭了连接。
2. 客户端和服务器之间的网络连接出现问题，导致连接被重置。
3. 服务器端的防火墙或其他网络设备阻止了连接。

要解决这个问题，可以尝试以下几种方法：
1. 检查服务器端是否正常运行，并确保没有意外关闭连接的情况发生。
2. 检查网络连接是否正常，可以尝试重新启动网络设备或更换网络连接。
3. 检查防火墙或其他网络设备的设置，确保没有阻止连接的规则。
