I have a problem compilling an example code
Hello. I'm a complete newbie. I was trying to compile this code
import javax.microedition.media.*;
import javax.microedition.amms.control.tuner.*;
import java.util.Date;
import java.io.IOException;
publicclass TunerExample{
Player radioPlayer;
TunerControl tunerControl;
RDSControl rdsControl;
/**
* Initializes and switched on the radio.
*/
void initializeRadio(){
try{
radioPlayer = Manager.createPlayer("capture://radio");
radioPlayer.realize();
radioPlayer.addPlayerListener(new MyPlayerListener(this));
tunerControl = (TunerControl)
radioPlayer.getControl("javax.microedition.amms.control.tuner.TunerControl");
tunerControl.setStereoMode(TunerControl.STEREO);
// Then, let's get the RDSControl:
rdsControl = (RDSControl)
radioPlayer.getControl("javax.microedition.amms.control.tuner.RDSControl");
if(rdsControl !=null){
//Let's turn on the automatic switching
//to possible traffic announcements:
rdsControl.setAutomaticTA(true);
}
radioPlayer.start();
// Now that the radio is on let's first find a radio station
// by seeking upwards from 91.0 MHz:
int freq = tunerControl.seek(910000, TunerControl.MODULATION_FM,true);
if(freq==0){
// no FM broadcasting found, do some error handling here...
return;
}
}catch (MediaException me){
}catch (IOException ioe){
}
}
/**
* Shows on the console some RDS data.
* This method is called from MyPlayerListener.
*/
void updateRDSDisplay(){
if(rdsControl !=null){
String channelName = rdsControl.getPS();
String radioText = rdsControl.getRT();
String programmeType = rdsControl.getPTYString(true);
// update the application UI to show the information:
System.out.println(channelName +", " + radioText);
System.out.println("genre:" + programmeType);
Date date = rdsControl.getCT();
if(date !=null){
System.out.println("The local time is " + date);
}
}
}
}
/**
* Listens RDS_NEW_DATA events and calls TunerExample.updateRDSDisplay
* when such an event is received.
*/
class MyPlayerListenerimplements PlayerListener{
TunerExample tunerExample;
public MyPlayerListener(TunerExample tunerExample){
this.tunerExample = tunerExample;
}
publicvoid playerUpdate(Player player,
java.lang.String event,
java.lang.Object eventData){
if(event == RDSControl.RDS_NEW_DATA){
tunerExample.updateRDSDisplay();
}
}
}

Here is the console code:

It compiles but doesn't run. How can I fix it?
