我有一个下面给出的代码。但是,当我尝试编译代码时,出现以下错误。
MyClient.java:12: error: unreported exception UnknownHostException; must be caught or declared to be thrown
InetAddress address = InetAddress.getByName("localhost");
我在代码中发现了上述异常。我不知道为什么会这样。?
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.lang.ClassNotFoundException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
public class MyClient {
public static void main(String[] args) {
InetAddress address = InetAddress.getByName("localhost");
int count = 0;
try {
/*
* Create a connection to the server socket on the server application
*/
Socket socket = new Socket(address, 9090);
/*
* Read and display the response message sent by server application
*/
ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
System.out.println("Created client socket and Input Stream Reader");
while (true) {
if (count < 1000) {
String message = (String) ois.readObject();
System.out.println("OFMessage: " + message);
count++;
} else {
break;
}
}
ois.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
