Arunkumar Pandyan Ramar Error in Apex Module
Hi,
Executing the 'generateStringArray' method failed. Either the method does not exist, is not static, or does not return the proper number of strings."
My code is as shown below.
public class StringArrayTest {
public static List<String> generateStringArray(Integer n){
List<String> str = new List<String>(n);
for(Integer j=0;j<n ;j++){
str.add('Test '+String.valueOf(j));
}
return str ;
}
}
When I test this on the debug-->open execute anonymous window,
with the following code, it runs successfully.
List<String> ls = StringArrayTest.generateStringArray(10);
for (Integer m=0;m<10;m++){
System.debug(ls[m]);
}

Please remove n in list of string:
List<String> str = new List<String>();
please check once and let me know in case any help need.
Thanks

It worked like a charm. No wonder it was sending back 10 null entries and then the correct 10 values.
Thanks again.

Please try below code:-
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; } }And go :Your Name>Developer Console>Debug>Open Execute Anonymous Window
Paste below code in it
list<string> myArray = StringArrayTest.generateStringArray(10); system.debug('************'+myArray);The Apex class must be called 'StringArrayTest' and be in the public scope.--> public class StringArrayTest{
The Apex class must have a public static method called 'generateStringArray'.
-->public static List<String> generateStringArray(Integer n) {
The 'generateStringArray' method must return an array (or list) of strings.
-->public static List<String> generateStringArray(Integer n) {
Each string must have a value in the format 'Test n' where n is the index of the current string in the array.
s= 'Test ' + x;
The number of returned strings is specified by the integer parameter to the 'generateStringArray' method.
public static List<String> generateStringArray(Integer n) {
