Help me, I don't even understand the question.

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
    return fieldName;
  }

}

"Validation" challenge on Java Object

I honestly do not understand what to do here, I barely understand what is requested.

You need to check two things about the passed in fieldName in this challenge.

  1. Make sure that the first character of fieldName is a lowercase m.
  2. Make sure that the second character is an uppercase character.

For example, if I passed in mDate it would be fine, but things like mdate or Date would not be.

Make any sense?

Happy coding,
Ken
