先看一个枚举类的代码：

1. package game;
   
2. 
   
3. public enum Chessmen {
   
4.          WHITE("○"),BLACK("●");
   
5.          private String chessmen;
   
6.          private Chessmen(String chessmen)
   
7.          {
   
8.                  this.chessmen = chessmen;
   
9.          }
   
10.          public String getChessmen()
    
11.          {
    
12.                  return chessmen;
    
13.          }
    
14. }

复制代码

说明：枚举类用enum代替了class，构造方法用的是private，目的就是为了创建对象的唯一性。
转化为class类如下：

1. package game;
   
2. 
   
3. public class Chessmen1 {
   
4.         public final static  Chessmen1 WHITE = new Chessmen1("○");
   
5.         public final static  Chessmen1 BLACK = new Chessmen1("●");
   
6.         private String chessmen1;
   
7.         private Chessmen1(String chessmen1) {
   
8.                 this.chessmen1 = chessmen1;
   
9.         }
   
10.         public String getChessmen1() {
    
11.                 return chessmen1;
    
12.         }
    
13. }

测设代码如下：

1. package game;
   
2. 
   
3. public class Test {
   
4. 
   
5.         /**
   
6.          * @param args
   
7.          */
   
8.         public static void main(String[] args) {
   
9.                 // TODO Auto-generated method stub
   
10.                 String white = Chessmen.WHITE.getChessmen();
    
11.                 String black = Chessmen.BLACK.getChessmen();
    
12.                 System.out.println(white + black);
    
13.                 System.out.println("/**************************/");
    
14.                 String white1 = Chessmen.WHITE.getChessmen();
    
15.                 String black1 = Chessmen.BLACK.getChessmen();
    
16.                 System.out.println(white1 + black1);
    
17.         }
    
18. 
    
19. }
