Hi,

 

You have to make one change in your code.

see below code.

 

if(ListQA.size()>0)
    {
    SubListQA.add(ListQA[0]);
    }
    if(ListQA.size()>2)
    {
    SubListQA.add(ListQA[2]);
    }
    system.debug('SubListQA' +SubListQA);
    }

Hi Taruni,

 

You have to put if condition to check the size of the List1 to resolve the List index out of bound issue.

 

List<String> List1 = new List<String>{'A','B','C'};
List<String> List2 = new List<String>();
if(List1.size() > 0){
	List2.add(List1[0]);
}
if(List1.size() > 1){
	List2.add(List1[2]);
}

I was able to add List[0] to sublistQA but on UI for list[2], I am getting System.ListException: List index out of bounds: 2
