枚举类型怎么写

//需要注意枚举参数必须放在私有构造函数前面

public enum Call_statusEnum {
//0失败；2未计算；3正在计算；4已计算；5手工重新计算 6:自动重新计算
fail("0","失败"),
not_calculate("2","未计算"),
being_calculated("3","正在计算"),
already_calculate("4","已计算"),
manual_re_calculation("5","手工重新计算"),
automatic_re_calculation("6","自动重新计算");

private Call_statusEnum(String key, String name) {
this.key = key;
this.name = name;
}

private String key;

private String name;

@Override
public String toString(){
return key;
}

public String getKey() {
return key;
}

public void setKey(String key) {
this.key = key;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

}
