Enums and keyboard input

Question

I am currently enrolled in a java class. I am working on a project about enums and switch statements. I get what enums and switch statements are but what I don't get is the input/output. I need the user to be able to pick one of four anwsers.
This might be something obvious but I am new to this.

Answer 1

enum Command {SIT, HEEL, ROLL_OVER, BEG};
public class EnumExample {
    public static void main(String[] args) {
        String[] inputs = {"SIT", "HEEL", "ROLL_OVER", "BEG"};
        for(String input : inputs) {
            Command cmd = Command.valueOf(input);
            System.out.println(cmd);
}valueOf?
