如果ReplyMessage是 功能界面 ，则可以
paramsValues[idx++] = reply -> message.reply(reply);
这是您问题中其他类的存根实现的完整示例：
// Stub classes
class JsonObject { }
@FunctionalInterface
interface ReplyMessage<T> {
void reply(T jo);
}
class LambdaDemo {
public static void main(String args[]) {
// Dummy variables
ReplyMessage<JsonObject> message = new ReplyMessage<JsonObject>() {
public void reply(JsonObject jo) {}
};
ReplyMessage[] paramsValues = new ReplyMessage[5];
int idx = 0;
// Your code, lambdafied
paramsValues[idx++] = reply -> message.reply(reply);
// Or,
// paramsValues[idx++] = message::reply;
// But then you Could perhaps do with just ...
// paramsValues[idx++] = message;
}
}
