Hi Lukesh,

Please update your code like below.
public class AccountUtility { 

public static void viewAnnualRevenue () {
list<account> accList = new list<account>();
String acctRev;
for(Account acc : [SELECT id,Name, AnnualRevenue FROM Account]){
account a = new account(); =;
a.AnnualRevenue = acc.Name + ': ' + acc.AnnualRevenue;
if(accList.size() > 0){ update accList;}


Please Mark this one as best answer, Kinldy let me know if you are facing any issue.
