Boudewijn Timmers Trailhead Getting Started With Apex not correct?
Hi there,
have an issue with the first Apex challenge in the Developer beginner module. As far as I can see I did it all right but the challenge won't accept. I need to create a list of strings with format 'Test n' where n is the number of the entry in the list. The lenght needs to be defined through a parameter. Here's my code (including a debug which shows me the correct strings):
public class StringArrayTest {
Public static void generateStringArray (Integer provide_count) {
List<String> TestString = new List<String>();
for(Integer i=0;i<provide_count;i++) {
TestString.add('Test '+string.valueof(i));
System.debug(TestString);
}
}
}
What am I doing wrong here?
regards,
Boudewijn

try this code
public class StringArrayTest { public static List<String> generateStringArray(Integer n) { List<String> myArray = new List<String>(); for(Integer i=0;i<n;i++) { myArray.add('Test '+i); System.debug(myArray[i]); } return myArray; } }ThanksMark it best answer if it helps you :)

thanks, that worked! Basically I can see two differences:
- in adding the string to the array you don't use string.valueof(i) but just i; does apex simply convert the variable format? I am used to pascal in the old days which was much more restrictive and wouldn't let me do it like this :)
- line 11 which returns the Array; is this to return the array to the generateStringArray method?
Best regards,Boudewijn
yes this method return type is List<String> so in the end we use return myArray; statement so our generateStringArray method return an string array link
test 1, test 2, test3, ....test n..
i hop it helps you :)
