Creating a Text based Menu!

Question

Hey guys. I've been up for god knows how long trying to do this but i cant figure out how. I am trying to create a text based menu looking somewhat like this:
Add Client (a)
List Clients (b)
Add Video (c)
List Videos (d)
Exit (q)
I have the methods written for adding videos and clients to files, working on how to read them back (FileReader?), but the main question here is, how do i link those possible answers (a,b,c,d,q) to the methods i have written? P.S. the methods are not located in the same class as the code for the menu.
Help will ensure a couple hours good sleep on my part and a passing grade in this course. Thanks in advance.

InputStreamReader input = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(input);
String strInput = br.readLine();
if (strInput.equals("a")) {
    //call responding method
} else if (strInput.equals("b") {
    //call responding method
} else if (strInput.equals("c") {
    //call responding method
} else if (strInput.equals("d") {
    //call responding method
} else if (strInput.equals("q") {
    //call responding method
}
