常量与枚举 一、常量定义方法 常量是其值固定不变的量，一般可以分为字面常量和命名常量，如数字1，2，1.3，字符串“abc”，这些就是字面常量，而命名常量是我们使用一些有意义的名称来代表字面常量值，通常命名常量有助于我们更好地理解程序的逻辑。 在Java中，我们通常使用public static final ... 方式来定义常量，如： public static final int MAX_VALUE = 1000; 在JDK1.5之前，我们如果需要表示一组相关的常量，可以使用如下方法完成： 01./** 02. * 星期 03. * @author 04. * 05. */ 06.public class WeekDay { 07. public static final int MONDAY = 1; // 星期一 08. public static final int TUESDAY = 2; // 星期二 09. public static final int WEDNESDAY = 3; // 星期三 10. public static final int THURSDAY = 4; // 星期四 11. public static final int FRIDAY = 5; // 星期五 12. public static final int SATURDAY = 6

I am trying to perform not very complex image analysis to try and find distinct shapes and calculate some of their parameters like area and perimeter (in pixels) and I am trying to do this in Haskell (I wanted to do that to try and work with functional programming language). The first task in line is to count the amount of spoons on the image: I am using Friday Haskell package to work with images. My idea was to use the Friday's edge detection and then fill all of the enclosed areas with it's fill function. The first one would require me to iterate over image's pixels until i've stumbled upon
