Is my logic flawed here or? Because this is super frustrating.

Question

So do I need to wrap this in a try catch block or? Because the current compiler error is it doesn't like the word IllegalArgumentException. It says it's an invalid symbol?
```TeacherAssistant.java
public class TeacherAssistant {
  public static String validatedFieldName(String fieldName) {
    // These things should be verified:
       if (fieldName.charAt(0) == 'm' || Character.isUpperCase(fieldName.charAt(1)) == true){
       throw new IllegalArgumentExcepton("Wrong");
       }

// 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;
  }
}
```

First, you misspelled Exception, leaving the i off, which is causing the invalid symbol error. Second, you are throwing the exception when the field name is OK, but returning it when it's not which is the exact opposite of what you need to do here.
