Method does not exist or incorrect signature: void generateStringArray(Integer) from the type StringArrayTest

Hi,
i am getting error while solving trailhead challange. please find below error.

"Method does not exist or incorrect signature: void generateStringArray(Integer) from the type StringArrayTest"

I tried some code given as best answers.

1. First Code I tried
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;
}
}

2. Second Code I tried
public class StringArrayTest {
public static List<String> generateStringArray(Integer n) {
List<String> List1 = new List<String>();
for(Integer i =0; i < n; ++i)
List1.add('Test ' + i);
return List1;
}
}

I am executing this code from DEBUG > Open Execute Anonymous Window and writing below code to call method.

StringArrayTest.generateStringArray(5);

Please suggest, How can I fix this

Thanks
Pradeep

Hi Pradeep,
Greetings to you!

- I read your problem and implemented in my Org. Please use the below Execute Anonymous and class [ Solved]: -
  
Class : -
    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;
        }
    }

Execute Anonymous : -

    List<String> values=StringArrayTest.generateStringArray(5);
    System.debug('values-->'+values);
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

Hi Pradeep,
Greetings to you!

- Your class is not saved after changes. please first save the apex class using 'Ctrl+s'.
- Then use 'Execute Anonymous'.
- Please find below screenshot for correction.
