title: I'm having issues writing Javadoc comments for main method's @param
body: <p>I'm very new to Java and taking an online course with little feedback.</p>
  
  <p>I think I have the program completed okay, but my prof requires comments to be done and I've had no guidance on them.  My biggest area seems to be the @param comments.  I've tried putting different things in there but nothing is correct.  Can anyone tell me what I'm doing wrong? Give me a link for easy to read info on @param comments.</p>
  
  <p>Here's my code:</p>
  
  <pre><code>/**
   * 
   */
  package edu.westga.cs6311.rectangles;
  
  import java.awt.Rectangle;
  
  /**
   * The RectangleIntersection class creates two rectangles that overlap (making a third rectangle) with a fourth rectangle not overlapping.
   * @author Tanya Fairbanks
   * @version 9/8/2013
   */
  public class RectangleIntersection {
  
      /**
       * The main method is where the rectangles are created.
       * @param   rectangle1  the original rectangle
       * @param   rectangle2  the overlapping rectangle
       * @param   rectangle3  the rectangle made from intersecting rectangle1 &amp; rectangle2
       * @param   rectangle4  the rectangle made that does not intersect with rectangle3
       */
      public static void main(String[] args) {
          // make 2 overlapping rectangles 
  
          Rectangle rectangle1 = new Rectangle(3, 12, 5, 3);
          Rectangle rectangle2 = new Rectangle(5, 11, 6, 4);
  
          System.out.println(rectangle1);
          System.out.println(rectangle2);
  
          //intersection of rectangles 1 &amp; 2 is rectangle3
          Rectangle rectangle3 = rectangle1.intersection(rectangle2);
          System.out.println(rectangle3);
  
  
          //figure the area of rectangle3
          double width = rectangle3.getWidth();
          double height = rectangle3.getHeight();
          double area = width * height;
          System.out.println("Expected area: 9.0 ");
          System.out.println("Calculated area: " + area);
  
          //create 4th rectangle that doesn't overlap 3rd
  
          Rectangle rectangle4 = new Rectangle(1, 15, 13, 12);
          System.out.println(rectangle4);
  
          //find intersection of 3rd and 4th rectangles
          Rectangle theIntersection = rectangle3.intersection(rectangle4);
          System.out.println(theIntersection);
  
          //print expected area and calculated area of theIntersection
  
          double width2 = theIntersection.getWidth();
          double height2 = theIntersection.getHeight();
          double area2 = width2 * height2;
          System.out.println("Expected area: 0.0");
          System.out.println("Calculated area: " + area2);
  
  
  
      }
  
  }
