System.out.println ....syntax error?

Question

Hi,
I am workin on my first java program here...and althought my classes compile just fine I can't manage to get what I want to appear on the screen on Button action....
Clicking on cost should trigger the appearance of the total cost...but nothing happens.
Can you have a look and tell me where I went wrong please?

public class Booking extends Applet implements ItemListener,ActionListener
String[][] c = { {"French Language","250","130","70"}, {"Painting","270","140","70"}, {"Yoga","250","130","70"} };
Courses courses_list = new Courses(c);
Choice ChoiceCourse;
Choice ChoicePeople;
Checkbox cb1, cb2, cb3;
boolean fulltime = false;
boolean parttime = false;
boolean concessions = false;
Button b1;

int p1;
int price;
public void init()
  add(new Label("Courses available for booking : "));
  ChoiceCourse = new Choice();
  add(ChoiceCourse);
//the following populates the ChoiceCourse dropDown Menu with the Courses'Titles

    ChoiceCourse.addItem(courses_list.getTitle(i));

Thanks for the guidance and the explanations. I've improved my code according to your recommendations (1, 2 &3) and it compiles just fine.
However, the println still doesn't work...but there is improvement:
When I run my applet using the AppletViewer at the very end I get a log of what happened...and it's now showing:
"D:\JBuilder8\jdk1.4\bin\appletviewer.exe Booking.html
total cost of your selection is: �0"
Which means that the println is being called but is not printing where it should be (on my screen)....the other problem is that it is obviously not properly calculating the total cost since it shouldn't be �0.
Here is my new (improved) code, and below is the code for the Courses class (which does some of the calculation):

    ChoiceCourse.addItem(courses_list.getTitle(i));
    i++;

//the following populates the ChoicePeople dropDown Menu with "numbers" from 1 to 10
