一个简单，不实用的枚举类案例

public enum Vip {
	vip1, vip2, vip3, vip4,vip5;
	public static void main(String[] args) {
		Vip vip=vip1, vip2, vip3, vip4,vip5;
		switch (vip) {
		case vip1:
			System.out.println("当前等级为vip1");
			break;
		case vip2:
			System.out.println("当前等级为vip2");
			break;
		case vip3:
			System.out.println("当前等级为vip3");
			break;
		case vip4:
			System.out.println("当前等级为vip4");
			break;
		case vip5:
			System.out.println("当前等级为vip5");
			break;
		default:
			break;
		}
	}
