Why does Socket.connect uses a SocketAddress rather than a InetSocketAddress?
Question
Why does Socket.connect uses a SocketAddress rather than a InetSocketAddress?
I read the source code of Socket.connect , it just cast a SocketAddress to a InetSocketAddress , and it throws a IllegalArgumentException if the SocketAddress could not cast to a InetSocketAddress .
I am very confused about the significance of this.

基本思想可能是Socket类的将来版本可以支持其他类型的连接。
