Still Cannot Find Symbol

[SamJava_the_Hut]

I declared the fields in the main method of my code, but it still says "Cannot Find Symbol". Here's the code:

/*
 * Drilling into the basics of object creation.
 */
package chapter4;

/**
 *
 * @author User
 */
public class CreateObjectDemo {
    
    public static void main(String[] args) {
		
        int Rectangle;
        int Point;
                
        // Declare and create a point object and two rectangle objects.
        Point originOne = new Point(23, 94);
        Rectangle rectOne = new Rectangle(originOne, 100, 200);
        Rectangle rectTwo = new Rectangle(50, 100);
        
        /*
         * WTF? I declared both Rectangle and Point above, and I'm still getting
         * red (between this block comment and int Point;). Why?
         */
		
        // display rectOne's width, height, and area
        System.out.println("Width of rectOne: " + rectOne.width);
        System.out.println("Height of rectOne: " + rectOne.height);
        System.out.println("Area of rectOne: " + rectOne.getArea());
		
        // set rectTwo's position
        rectTwo.origin = originOne;
		
        // display rectTwo's position
        System.out.println("X Position of rectTwo: " + rectTwo.origin.x);
        System.out.println("Y Position of rectTwo: " + rectTwo.origin.y);
		
        // move rectTwo and display its new position
        rectTwo.move(40, 72);
        System.out.println("X Position of rectTwo: " + rectTwo.origin.x);
        System.out.println("Y Position of rectTwo: " + rectTwo.origin.y);
    }
    
}

I got this code from here:

http://docs.oracle.com/javase/tutori...O/objects.html

I don't see any import statements. Nor in the JDK Doc did I see a constructor of Rectangle(Point, int, int).

From java tutorial :
" You will need all three source files to compile this program. "
http://docs.oracle.com/javase/tutori...bjectDemo.java
http://docs.oracle.com/javase/tutori...les/Point.java
http://docs.oracle.com/javase/tutori...Rectangle.java
Hope it will work now

You don't need any source files other than the OP's. Just the pre-compiled classes which are available via imports.

Yes but how do you get those precompiled classes when you don't download their sources and compile them? Even though the names mights suggest it, they're not the standard AWT Point and Rectangle classes.

[jim829]

Yeah! My response was probably a bit hasty. I figured it was too much of a coincidence to mimic all the constructors exactly except one. And not importing the classes would have been a possible cause.

I'm using Netbeans IDE to write my code. Are each of my project's packages only supposed to have one main class .java file? If so, does that mean I can only have one super class per package?

[jim829]

A package may have many classes and a project may involve many packages. The class which contains the static main method is typcially the point of entry when the app is loaded and run by the JVM.
