Courses Plus Student 3,274 PointsWhat wrong with this code? how am i using the isuppercase method wrong?
how am i using the method wrong?
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.charAt(0)!='m') )
throw new IllegalArgumentException ("nu e prima litera m");
if ( (isUpperCase(fieldName.charAt(1))) )
throw new IllegalArgumentException ("nu e prima litera m");
return fieldName;
}
}

Here is the correct code:
public class TeacherAssistant {
public static String validatedFieldName(String fieldName) {
if (fieldName.charAt(0) != 'm' || !Character.isUpperCase(fieldName.charAt(1)) ) {
throw new IllegalArgumentException(" Illegal field name. ");
}
return fieldName;
}
}
If you have any questions, feel free to ask!

Courses Plus Student 3,274 Pointsthanks.. i didn.t realize that i have to user Character.isUpperCase... considering the fact that i didn't have the Character class in my code.
But that is probably because Character class is a general class included in java so ... yeah... i get it.
Thanks a million!
