映射枚舉的定義
enum ColorEnum {
YELLOW("YELLOW", "黃色"),
WHITE("WHITE", "白色"),
GREEN("GREEN", "綠色"),
BLUE("BLUE", "藍色"),
RED("RED", "紅色");
private final String description;
private final String code;
// 每次實例都會調(diào)用一次 注意：新增一條數(shù)據(jù)就會用調(diào)用實例，一共五次
ColorEnum(String code, String description) {
System.out.println("編碼：" + code + "描述：" + description);
this.code = code;
this.description = description;
}
public String getCode() {
return code;
}
public String getDescription() {
return description;
}
}
場景使用
System.out.println(ColorEnum.YELLOW.getCode());
System.out.println(ColorEnum.YELLOW.getDescription());
