Object to Int

[Slaughterman]

Hey guys,

I have a little problem with one of my program. I have a server/client scheme and I'm receiving a int value from my client into my server.
The thing is my server see it as an Object, and I need to change it back to an Int because later on my client I have a function which permit to lower the int number on my server. Don't really know if my explanation is very clear, but anyway here is the part of the code (summarized) which cause me trouble:

public String doLesson(){
int places = 0;
places = Integer.parseInt(receive()); // Solution not working i found on google
Lesson i = new
Lesson(lessonNo,description,places.intValue(),loca tion);
server.put(lessonNo, i);
return "Lesson added";
}

It's strange because for a double value for example I have no problem at all:

public String doLesson(){
Double places = 0.00;
places = (Double) receive(); // If only it was this simple with int, just adding (Int) receive(); - but not working :(
Lesson i = new
Lesson(lessonNo,description,places.doubleValue(),l ocation);
server.put(lessonNo, i);
return "Lesson added";
}

Any ideas ?

Cheers,

Clement

When you System.out.println(recieve()); what does it look like? Because the Integer.parseInt(...) is trying to parse that exact string; my guess is that it doesn't look like an integer.

System.out.print("Enter number of places\t");
String places = getString();
send(new Integer(places));

I found the solution, here is the updated code:

public String doLesson(){

int places = 0;

places = (Integer) receive();

Lesson i = new
Lesson(lessonNo,description,places,location);
server.put(lessonNo, i);
return "Lesson added";
}

Sorry for the trouble :)
