    Unhappy 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;
    	 date: new Date();
    	 Rectangle( double w, double h, String c ){ // CONSTRUCTOR
    	 	width = w;
    		height = h;
    		color = c;
    		date = new Date();
    	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();
    	 arr[i] = r;
    	 k = (int)(Math.random()*4)+1;

    Default Re: client program rectangle

    What happens when the program is compiled and executed? If it generates output, copy the output, paste it here and add some comments saying what the problem is.
    If you don't understand my answer, don't ignore it, ask a question.
