Everything looks fine, what is wrong with the syntax
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
char c = fieldName.charAt(0);
if (Character.toLowerCase(c) != 'm') {
throw new IllegalArgumentException("member field must start with an m");
}
return fieldName;
}
}

1,409 PointsLooks good. You got number 1 down. Now all you need to do is make sure that the second letter is not lower case.
HINT: Use isUpperCase()
and !
.
