Chaitra GV Trialhead challenge error :Executing the 'generateStringArray' method failed
Hi, I'm facing below error on trialhead challenge even though the code is correct. Got expected results in the debug window as well.
Executing the 'generateStringArray' method failed. Either the method does not exist, is not static, or does not return the proper number of strings.
Please help.
Code:
public class StringArrayTest
{
public static List<String> generateStringArray(Integer n)
{
String[] arr = new List<String>();
for(Integer i=0;i<n;i++)
{
arr.add('Test'+i);
}
System.debug('The array is:'+arr);
return arr;
}
}

for(Integer i=0;i<n;i++)
{
arr.add('Test'+i);
}
System.debug('The array is:'+arr);
return arr;
}
}
The problem in your code is that you need to pass one space between 'Test '+i .
public class StringArrayTest {
public static String[] generateStringArray(Integer length) {
String[] myArray = new List<String>();
for(Integer i=0;i<length;i++) {
myArray.add('Test ' + i);
System.debug(myArray[i]);
}
return myArray;
}
}
Please mark it as best Answer if you find it helpful.

Hi Chaitra GV,
Please find below a little fix for your issue.
The problem was the space between Test and the number you had: Test0, Test1.... and what was necessary was Test 0, Test 1,
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; } }Please make it best if it helps you.
Thanks
