Java Java Objects (Retired) Delivering the MVP Validation

Teacher Assistant Validation

I must ensure that the first letter of the fieldName is 'm'. Then i must ensure the the second letter of the field name is capitalised.

I am getting a compiler error and clicking preview does not show me where i made a mistake. Please help. Frustration is kicking in

TeacherAssistant.java
public class TeacherAssistant {

  public static String validatedFieldName(String fieldName) {
    if(fieldName.charAt(0) !== 'm'){
     throw new IllegalArgumentException("First character must be m");
    }
       if(!Character.isLetter(fieldName.charAt(1)) || !Character.isUpperCase(fieldName.charAt(1))   ){
             throw new IllegalArgumentException("Second letter must be capitalised");
       }
    // 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
    return fieldName;
  }

}

Took a closer look again and it seems like the !== operator in the first if statement might be the culprit. It should be != instead:

if(fieldName.charAt(0) != 'm')

Thank you. It finally compiled after removing that extra =
