2,873 PointsDelivering MVP stage1 validation question unable to find the error messgaes
I am unable to see any error messages in the preview screen but whenever i check my work it keeps saying that there is some error. Not able to clear the challenge coz of no error messages. any solution??
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 IllegalArgumentException("should start with m");
}
if(!isUpperCase(fieldName.charAt(1)))
{
throw IllegalArgumentException("second char has to be Uppercase");
}
return fieldName;
}
}

Treehouse TeacherHmmm...seems like you should be throwing a new exception.
Hope that hint helps!

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("should start with m"); } if(!isUpperCase(fieldName.charAt(1))) { throw new IllegalArgumentException("second char has to be Uppercase"); } return fieldName; }
