Hello Server
--
```java
import java.util.ArrayList;
import java.util.List;
import io.netty.channel.ChannelHandlerContext;
import rpckids.server.IMessageHandler;
import rpckids.server.MessageOutput;
import rpckids.server.RPCServer;
class FibRequestHandler implements IMessageHandler {
private List fibs = new ArrayList<>();
{
fibs.add(1L); // fib(0) = 1
fibs.add(1L); // fib(1) = 1
}
@Override
public void handle(ChannelHandlerContext ctx, String requestId, Integer n) {
for (int i = fibs.size(); i < n + 1; i++) {
long value = fibs.get(i - 2) + fibs.get(i - 1);
fibs.add(value);
}
ctx.writeAndFlush(new MessageOutput(requestId, "fib_res", fibs.get(n)));
}
}
public class DemoServer {
public static void main(String[] args) {
RPCServer server = new RPCServer("localhost", 8888, 2, 16);
server.service("fib", Integer.class, new FibRequestHandler());
server.start();
}
}
```
Hello Client
--
```java
import rpckids.client.RPCClient;
public class DemoClient {
private RPCClient client;
public DemoClient(RPCClient client) {
this.client = client;
this.client.rpc("fib_res", Long.class).rpc("exp_res", ExpResponse.class);
}
public long fib(int n) {
return (Long) client.send("fib", n);
}
public static void main(String[] args) {
RPCClient client = new RPCClient("localhost", 8888);
DemoClient demo = new DemoClient(client);
for (int i = 0; i < 20; i++) {
System.out.printf("fib(%d) = %d\n", i, demo.fib(i));
}
}
}
