Enquiries for if-else statement structure

Question

I want to design an choice program for user. I have designed something like this, there is no last "else" because ans D is to exit the loop without printing anything.

do
{
If ( ans == A)
{}
else if ( ans == B)
{}
else if (ans == C)
{}

} while ( ans != D);

Is my design very weird ? Or there is any suggestion in terms of design. (please take note option D is just exit)

Answer 1

No, it just fine if you use equals() method
