Question

im creating a method where a user input has to type A/B to get a return. how do i make my code case insensitive to make it work?

 String examcode (String code) {
    if (code.compareToIgnoreCase("A")) {
        EXAM_NAME = "Subject A";
    }
    else if (code.compareToIgnoreCase("B")) {
         EXAM_NAME = "Subject B";
    }
    else {
        EXAM_NAME = "no code";
    }
    return EXAM_NAME;
}

Just use the method –
String.equalsIgnoreCase(java.lang.String) which returns a boolean and does the job for what you are looking for.

if (code.compareToIgnoreCase("A")) is not valid since compareToIgnoreCase returns int.
