Hello , What's wrong with this 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' && (!isUpperCase(fieldName.charAt(1))))
      throw new IllegalArgumentException("Message "); 
   else return fieldName;
  }

Remember you don't need the else. The exception will break out of the method and bubble up.

the isUpperCase method is a method that belongs to the Character class. so you need to put Character. in front

 if (fieldName.charAt(0) != 'm' && (!Character.isUpperCase(fieldName.charAt(1))))
      throw new IllegalArgumentException("Message "); 
   else return fieldName;
  }
