Hi Firas,

Please use the below function getSublist : 


public Static List<String> getSublist(List<String> oldStringList, Integer limit){
List<String> newStringList = new List<String>(); 
for(Integer i = 0; i < oldStringList.size(); i++){
 if(i < limit){ 
     newStringList.add(oldStringList[i]); 
 } 
} 
System.debug('oldStringList: '+ oldStringList); 
System.debug('newStringList : '+ newStringList);
return newStringList ;
}

In Execute Anonymous try: 

List<String> oldStringList = new List<String>();
oldStringList.add('a');
oldStringList.add('b');
oldStringList.add('c');
oldStringList.add('d');
oldStringList.add('e');
oldStringList.add('f');

System.debug('newStringList : '+ getSublist(oldStringList ,2));
