Bummer says "mFirstName go through but report my throw", I don't know why
public class TeacherAssistant {
public static String validatedFieldName(String fieldName) {
// These things should be verified:
// 1. Member fields must start with an 'm'
// 2. The second letter in the field name must be uppercased to ensure camel-casing
// NOTE: To check if something is not equal use the != symbol. eg: 3 != 4
if ( fieldName.indexOf(0) != 'm' || ! Character.isUpperCase( fieldName.indexOf(1) ) ){
throw new IllegalArgumentException("Don't fit the requirment");
}
return fieldName;
}
}
