Am I doing something really stupid?

Question

I can't understand why this won't compile, I must be doing something wrong, but I can't for the life of me figure out what:
import java.applet.Applet;
import java.awt.*;
public class myApplet extends Applet{
     Isosceles triangle=new Isosceles(2,2,5);
     int perim=triangle.getPerimeter();
     System.out.println(perim);
Errors:
myApplet.java:8: <identifier> expected
System.out.println(perim);
^
myApplet.java:8: cannot resolve symbol
symbol : class out
location: class java.lang.System
System.out.println(perim);
^
2 errors
Can anyone help?

Answer 1

You can't have code within a class body like that, a class body can only have declarations. You need to write a method (or constructor, or initializer block) where to put those lines.
Here's a popular way of doing it:
public class myApplet {
public static void main(String[] args) {
Isosceles triangle=new Isosceles(2,2,5);
int perim=triangle.getPerimeter();
System.out.println(perim);
(btw if you thought you are writing an applet where do you think the output from System.out.println will go?)
