Thread: client program rectangle

I have been trying to do these program for so long I think I almost got it all but there are some things I am not sure about,
so I am trying to print the number of rectangles created, but I do not understand how to do it, because I have defined already the number of rectangles created (10). Also I need to find and print the information of a rectangle with the largest area, I do not know how to do it . I am really new at these, I would really apreciate some help



these is my main class

public class Rectangle{
 	 private double width, height;
 
	 private static String color ="white";
 
	 private Date date;
 
	 private  static int rectangleCreated = 0; /// why is static?
 
	 Rectangle(){ // no arg constructor that  creates a default rectangle
 
		width =1;
		height =1;
 
	 rectangleCreated++;
 
	 date: new Date();
 
	 }
 
 
	 Rectangle( double w, double h, String c ){ // CONSTRUCTOR
 
	 	width = w;
 
		height = h;
 
		color = c;
 
		date = new Date();
 
		rectangleCreated++;
 
 
		}
 
	public static int rectangleCreated(){ 	// a method that returns number of rectangle created 
 
 
	 return rectangleCreated;
 
	 } 
 
 
 
	public double getHeight(){
 
		return height;
 
		}
	public void setHeight ( double h) {
 
		height = h;
 
		}
	public void setWidth ( double w) {
 
		width = w;
		}
 
	public static String getColor(){
 
		return color;
		}
 
	public static void setColor(String c){
		color = c;
 
		}
	public Date getDate(){
 
		return date;
 
		}
	public void setDate ( Date d){
 
		date = d;
 
				}
 
 
	public double getArea(){ // returns area
 
			return width*height;
 
		}
	public double getPerimeter(){ // returns perimeter
 
		return (2*width* height);
 
		}
	public String toString(){
 
		String S;
		S = "Rectangle width of" + width;
 
		S =  S + "and height of" +height;
 
		S = S + " was created on " + date.toString();
 
		return S;
 
			}
				}

and these the client program I am working on

import java.util.*; 
 
 
public class TestRectangle{
 
	public static void main (String[]args)
	{
 
 String[] colors = {"White","Blue","Yellow","Red","Green"};
 
 int k;
 
 
 
 
 
 Rectangle[] arr = new Rectangle[10];
  for(int i = 0; i < 10; i++) {
  	 Rectangle r = new Rectangle();
	 r.setWidth((Math.random()*40)+10); 
	 r.setHeight((Math.random()*40)+10);
	 arr[i] = r;
	 k = (int)(Math.random()*4)+1; 
	 System.out.println(colors[k]);
 
 
 
	   }
 
			} 
			 }
