: : : same game
: : :
: : :
: : :
: : : so plz help me
: :
: : Start by defining a class and add a method to show the menu. This
: : should be simple enough, just a couple of System.out.println()'s.
: : The add a method to ask the user for a choice and validate if the
: : choice is within the choices of the menu. This requires a couple of
: : if-statements. This method should return the choice made.
: : Finally tie them together in a while-loop in a third method or in
: : the main() itself.

Here are the two methods I talked about:
public class Menu {
public void showMenu() {
System.out.println("q: Quit");
}
public char getChoice() {
char choice = '\0';
String choices = "q";
while (choices.indexOf(choice) == -1) {
String s = System.console().readLine();
if (s == null || s.length() == 0)
choice = '\0';
else {
choice = s.charAt(0);
if (choices.indexOf(choice) == -1) {
System.out.println("Wrong choice. Try again");
}
}
return choice;
}
}
The rest is up to you.
