Hi the errors mean different things..

Error 1) you are using a member variable. Either you have not declared this member variable. Or you are trying to access a private member variable from another class.

Error 2) Not sure about this error, could be due to something else not working

Error 3) I think your filename may be bad. The filename for the .java file MUST be the same as the class name you are creating.

Can you please paste your code?

I really cant figure this out.

This is my current code: 

  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.charAt(0) == 'm') && Character.isUpperCase(fieldName.charAt(1))){
      return fieldName;
    }else {
      throw new IllegalArgumentException("This does not work");
    }

    return fieldName;
  }
