如何将用户输入字符串设置为ENUM Java

Question

So I want the user to input user input strings and store them into an ENUM but I'm not sure how to store the new strings in the ENUM.

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);

I don't think the Food(location, calories, fat); sets the input in the enum, what could I use in order to set it?

Not sure what you're trying to achieve by doing this, but you can drop final modifier from the enum fields, add getters and setters and store them once user input data. Eg:

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);
    }
}

Main

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);
}

Output

locat
calor
fat
PIZZA: locat calor fat
