Thread: I can't get classes to work.

I have two files. I tried coding a program where one file is my Rectangle class that finds and calculates area and perimeter, while the other file uses the Rectangle class and creates two objects. But I can't seem to get it to work. What's wrong with it?
"MyRectangleClassProgram"

import Rectangle.pkg.Rectangle;
 
public class MyRectangleClassProgram
{
   public static void main(String args[])
   {
        Rectangle = new rectangle1();
        Rectangle = new rectangle1();
 
        rectangle1.setLW(10.0);
        rectangle1.setLW(5.0);
        rectangle2.setLW(7.0);
        rectangle2.setLW(3.0);
 
 
        System.out.println("Perimeter of rectangle1 is ");
        System.out.println(rectangle1.calculatePerimeter());
        System.out.println("\n");
        System.out.println("Area of rectangle1 is ");
        System.out.println(rectangle1.calculateArea());
        System.out.println("\n");
        System.out.println("Perimeter of rectangle2 is ");
        System.out.println(rectangle2.calculatePerimeter());
        System.out.println("\n");
        System.out.println("Area of rectangle2 is ");
        System.out.println(rectangle2.calculateArea());
        System.out.println("\n");
 
 
      System.exit(0);
   }
}

"Rectangle"

class Rectangle
{
	public double length, width;
 
 
	public double getLW(double len, double wid){
        return length;
        return width;
    }
 
    public double setLW(double len, double wid){
        length = len;
        width = wid;
        return;
    }
 
	public double calculateArea(){
        return width * length;
    }
 
	public double calculatePerimeter(){
        return 2 * (width + length);
    }
}

All the information I have is given here. I'm given two tabs and I have to code in them. https://gyazo.com/a755525d125f1933cf0a14a507394611 It's online on a site called Cengage.

Yes all the code I have is there

What do you mean by that?

ok
