This works when i try in my environment, not sure whats wrong ...can someone check please

TeacherAssistant.java
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('m') != 0) {
      throw new IllegalArgumentException ("doesn't start with m");
    } else {
    return fieldName;
    }
  }

Hi there! That part does work! But you missed part of the instructions of the challenge.

// 2. The second letter in the field name must be uppercased to ensure camel-casing

You have no code to check that makes sure the second letter is upper case. Try adding this code and see if you can get it to pass. If you need more help, let us know :sparkles:

You need to check both the conditions to pass the test! Try and do it. Get back if you still can't figure it out.

That was silly of me, I realised after posting the question. Thanks for your time.
