public class MyEnum {

private final String name;

public  static final MyEnum red = new MyEnum("红色");

public  static final MyEnum green = new MyEnum("绿色");

public  static final MyEnum black = new MyEnum("黑色");

public  static final MyEnum yellow = new MyEnum("黄色"); 

public MyEnum(String name){

this.name = name;

}

public String getName(){

return this.name;

}

}

Java中自己实现枚举
