因此,我希望用户输入用户输入的字符串并将其存储到ENUM中,但是我不确定如何将新字符串存储在ENUM中。
public enum Food {
PIZZA("", "", ""),
private final String location;
private final String calories;
private final String fat;
Food(String location, String calories, String fat){
this.location = location;
this.calories= calories;
this.fat= fat;
}
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String location = input.nextLine();
String calories= input.nextLine();
String fat= input.nextLine();
Food(location, calories, fat);
我不认为食物(位置,卡路里,脂肪);在枚举中设置输入,我可以使用什么来设置它?
答案 0 :(得分:0)
不确定要执行的操作是什么,但是可以从枚举字段中删除final
修饰符,添加getter和setter并在用户输入数据后将其存储。例如:
public enum Food {
PIZZA;
private String location;
private String calories;
private String fat;
public String getLocation() { return location; }
public void setLocation(String location) { this.location = location; }
public String getCalories() { return calories; }
public void setCalories(String calories) { this.calories = calories; }
public String getFat() { return fat; }
public void setFat(String fat) { this.fat = fat; }
@Override
public String toString() {
return String.format("%s: %s %s %s", super.toString(), location, calories, fat);
}
}
主要
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Food.PIZZA.setLocation(input.nextLine());
Food.PIZZA.setCalories(input.nextLine());
Food.PIZZA.setFat(input.nextLine());
System.out.println(Food.PIZZA);
}
输出
locat
calor
fat
PIZZA: locat calor fat
