2,861 PointsLooks like syntax error at throw new IllegalArgumentException
throw new IllegalArugumentException("doesnt start with m"); ^ symbol: class IllegalArugumentException location: class TeacherAssistant 1 error
This is the error i get....
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.indexOf('m') != 0 && ! Character.isUpperCase(fieldName.charAt(1))) {
throw new IllegalArugumentException("doesnt start with m");
} else {
return fieldName;
}
}
}

Courses Plus Student 10,155 PointsThere's a typos mistake:
IllegalArugumentException
Instead of
IllegalArgumentException
There's also a logic mistake, take a look at the control statement you wrote:
You're saying: "if first char of fieldName is 'm' and second char is not uppercase, then raise an error" In order to satisfy the second point, you should replace with logical or ||
if( fieldName.indexOf('m') != 0 || ! Character.isUpperCase(fieldName.charAt(1))) {
throw new IllegalArgumentException("doesnt start with m");
} else {
return fieldName;
}
