我的輸出是「[B @ b42cbf」,沒有錯誤。如何在Java中打印字符串而不是地址?
它應該是一個字符串,表示「服務器檢查」。
如何修復我的代碼以輸出字符串而不是地址?
我打印對象的代碼已被更改多次,但現在如下所示。
System.out.println(packet.getMessage().toString());
我的數據包類如下。
import java.io.Serializable;
public class Packet implements Serializable {
final public short MESSAGE = 0;
final public short COMMAND = 1;
private String _ip;
private short _type;
private String _source;
private String _destination;
private byte[] _message;
public Packet(String ip, short type, String source, String destination,
byte[] message) {
this._ip = ip;
this._type = type;
this._source = source;
this._destination = destination;
this._message = message;
}
public String getIP() {
return this._ip;
}
public Short getType() {
return this._type;
}
public String getSource() {
return this._source;
}
public String getDestination() {
return this._destination;
}
public byte[] getMessage() {
return this._message;
}
}
我通過ObjectOutputStream發送數據包,然後將它收到ObjectInputStream中。該對象被封裝在(Packet)包中。你可以看到如何工作如下。
public void sendPacket(Packet packet) throws NoConnection {
if (this._isConnected) {
try {
this._oos.writeObject(packet);
this._oos.flush(); // Makes packet send
} catch (Exception e) {
e.printStackTrace();
this._isConnected = false;
throw new NoConnection("No notification of disconnection...");
}
} else {
throw new NoConnection("No connection...");
}
}
這是監聽者。
@Override
public void run() {
try {
this._ois = new ObjectInputStream(this._socket.getInputStream());
Packet packet = (Packet) this._ois.readObject();
this._listener.addPacket(packet);
} catch(Exception e) {
e.printStackTrace();
}
}
+1是的,你說得很對,這樣好多了。我應該對我的SO進行宵禁。 – 2011-12-21 08:43:04
