Erro ao criar um objeto do tipo Socket

import java.io.*;
import java.net.*;

public class DailyAdviceClient {
	
	public void go() {
		try {
			Socket s = new Socket("127.0.0.1", 5000);
			
			InputStreamReader streamReader = new InputStreamReader(s.getInputStream());
			BufferedReader reader = new BufferedReader(streamReader);
			
			String advice = reader.readLine();
			System.out.println("Today you should: "+advice);
			
			reader.close();
		} catch (UnknownHostException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} 
	}
	
	public static void main(String[] args) {
		DailyAdviceClient client = new DailyAdviceClient();
		client.go();
	}

}

Mas ai apareceu os seguintes erros:

java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.connect0(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(Unknown Source) at java.net.AbstractPlainSocketImpl.doConnect(Unknown Source) at java.net.AbstractPlainSocketImpl.connectToAddress(Unknown Source) at java.net.AbstractPlainSocketImpl.connect(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.(Unknown Source) at java.net.Socket.(Unknown Source) at atividades.headfirst5.DailyAdviceClient.go(DailyAdviceClient.java:10) at atividades.headfirst5.DailyAdviceClient.main(DailyAdviceClient.java:28 )

Gostaria da ajuda de vocês para tentar entender o que pode estar acontecendo. Obrigado :D
