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

5,225 PointsYou 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.
