illegalArgumentException

In this challenge, the task is to add illegalArgumentException if the displayed requirement are not met. how do I proceed?

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
    return fieldName;
  }public class static {boolean(validatedFieldName != mFieldname ||  mFieldName.mChar(1) != UPPERCASE_LETTER) throw (illegalArgumentException);
  }
}

You have to have a try and catch function like this

public static String...{ try{ if(condition) { block of code... } } catch (IllegalArgumentException iae){ System.out.printf("Sorry the error was\n %s \n", iae.getMessage()); } return fieldName; }

You'll notice that there are 2 \n so it makes your message clearer and cleaner.
