Java Java Objects (Retired) Delivering the MVP Validation

ValidateFieldName Challenge

Can somebody tell me what am I doing wrong here. I have done research and tried everything possible but it won't pass the test.

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.charAt(0) != 'm' || !Character.isUpperCase(fieldName.charAt(1)) {
      throw new IllegalArgumentException("Error"); 
    }
    return fieldName;
  }

}
