Interpreting user input as an enum instance

Question

I have the following Enum:

public enum Food {
APPLE,
BREAD,
PIE,
STEAK;
}

I want to store the user's chosen food like so Food food = scanner.next() (obviously this is incorrect). What would be a good way to do it?

Possible option would be to create a map of String : Food and use that based on String input from user. — chatton, Mar 18 '17 at 19:48

You can do the following:

Scanner scanner = new Scanner(System.in);

Food food;
String input = scanner.next();
for (Food item : Food.values()) {
    if(input.equals(item.name())) food = item;

}
