JAVA的枚举类型

枚举之前很少用，都是用常量来表示客观的可枚举不可变实例，难免不方便开发和维护，mark下这个类型，会有帮助

public class EnumStudy {

	public static void main(String[] args) {
		Gender g = Gender.hybrid;
		switch(g){
		case male:
			System.out.println("brave & strong");
			break;
		case female:
			System.out.println("nice & weak");
			break;
		case hybrid:
			System.out.println("nothing to say");
			break;
		}
	}
	private enum Gender{
		male, female, hybrid
	}
}
