如下代码:
public enum CardType { UNKNOW(0, "未知"), DEBIT_CARD(1, "借记卡"), CREDIT_CARD(2, "信用卡"); private final byte value; private final String desc; private CardType(int value, String desc) { this.value = (byte) value; this.desc = desc; } //循环枚举的静态方法 public static boolean ifInElements(int num){ for (CardType ele : CardType.values()) { if(num==ele.getValue()) return true; } return false; } public byte getValue() { return value; } public String getDesc() { return desc; } @Override public String toString() { return String.valueOf(this.getValue()); } }
