Java处理异常功能编程
我有这个代码：
private void handleReceivedMessage(String m) throws IOException {
switch(m) {
case "ping":
// code block
ping();
break;
default:
System.out.println("message not understood");
}
}
public DataServer(int port) throws IOException {
server = new Server(port, this::handleReceivedMessage);
server.acceptClient();
}
现在，我在此行中遇到了错误:: handlereceivedMessage： 未经手的例外：java.io.ioexception
如何解决这个问题？很明显，HandlereCeivedMessage功能确实抛出了IOException
I have this piece of code:
private void handleReceivedMessage(String m) throws IOException {
switch(m) {
case "ping":
// code block
ping();
break;
default:
System.out.println("message not understood");
}
}
public DataServer(int port) throws IOException {
server = new Server(port, this::handleReceivedMessage);
server.acceptClient();
}
now I get the error at the line this::handleReceivedMessage:
Unhandled exception: java.io.IOException
How do I solve this? It's clear that the handleReceivedMessage functions does throw an IOException

在不知道更多的情况下，我会尝试使用Try/Catch语句专门捕获Olivier建议的例外。如果我可以问，为什么不使用尝试/捕获来检查错误？
Without knowing more, I'd try using a try/catch statement specifically to catch the exception being thrown as Olivier is suggesting. If may I ask, why aren't you using try/catch for error checking?
