java枚举实例

实例一：

public enum OrderOption {
ASC,
DESC;

}

实例二（带参数构造函数）：

public enum OrderOption {
ASC("ASC"),
DESC("DESC");
String type;

OrderOption(String type){
this.type = type;
}

public String getType() {
return type;
}

public void setType(String type) {
this.type = type;
}
}

实例三（枚举公共方法）：

public static void main(String[] args) {
System.out.println(SeasonEnum.getSeason("spring"));
}

public enum SeasonEnum {
spring, summer, autumn, winter;
public static SeasonEnum getSeason(String position) {
if ("spring".equals(position)){
return spring;
}else if("summer".equals(position)){
return winter;
}else if("autumn".equals(position)){
return autumn;
}else{
return winter;
}
}
}
