Writing a switch statement

Question

Hi,
This might seem strange since normally when you write a switch statement you only use one char or integer, but how would you write a case that would accept two chars as its arg?
quick pseudo code.......
switch(input){
case ??:
case af:
etc etc..

Answer 1

I think I'm using the wrong arguement equalsIgnoreCase, but I'm not sure what else to use... I want to be able to go through these options until "lq" is typed and then it will display the list I've created and quit the loop.. Could anyone give me a clue at what I can do?
Thanks in advance!
while(status)
               System.out.print("Option (?? for help): ");
               input = keyboard.next();
               if (input.equalsIgnoreCase("??"))
                    System.out.println("\n" + "??" + " display these options" +
                              "\n" + "af" + " add given item as first" +
                              "\n" + "an" + " add given item while preserving natural order" +
                              "\n" + "rf" + " remove first item and report success" +
                              "\n" + "rg" + " remove first occurrence of given item and report success" +
                              "\n" + "rn" + " remove first item which is not in natural order and report success" +
                              "\n" + "ld" + " display list" +
                              "\n" + "le" + " make list empty" +
                              "\n" + "ls" + " sort the list, using rn and an" +
                              "\n" + "lq" + " display list and quit");
               else if (input.equalsIgnoreCase("af"))
                    System.out.println("Item: ");
               else if (input.equalsIgnoreCase("an"))
                    System.out.println("Item: ");
               else if (input.equalsIgnoreCase("rf"))
                    System.out.println("Test: ");
               else if (input.equalsIgnoreCase("rg"))
                    System.out.println("Test: ");
               else if (input.equalsIgnoreCase("rn"))
                    System.out.println("Test: ");
               else if (input.equalsIgnoreCase("ld"))
                    System.out.println("Test: ");
               else if (input.equalsIgnoreCase("le"))
                    System.out.println("Test: ");
               else if (input.equalsIgnoreCase("ls"))
                    System.out.println("Test: ");
               else if (input.equalsIgnoreCase("lq"))
                    System.out.println("Test: ");
          }
