    Hi Srikanth,

    Write this apex code:-

    //apex class

    public class AccountSelectClassController {

    //CONTROLLER CLASS

        public list<wrapaccount> wrapaccountList { get; set; }

        public list<account> selectedAccounts{get;set;}     

        public list<id> selectedrecordsIds{get;set;}

        public List<Contact> records{get;set;}

        

          public AccountSelectClassController (){

          

         //if(wrapaccountList ==null){

              wrapaccountList =new list<wrapaccount>();

              for(account a:[select id,name from account limit 10]){

               wrapaccountlist.add(new wrapaccount(a));

            

               }

            // }

          }

        //⌗⌗⌗ SELECTED ACCOUNT SHOWN BY THIS METHOD

          public void ProcessSelected(){

         selectedAccounts=new list<account>();

         selectedrecordsIds =new list<id>();

          

          for(wrapaccount wrapobj:wrapaccountlist){

               if(wrapobj.isSelected==true){

               selectedAccounts.add(wrapobj.accn);

               }

                

             }

              

              for(Account abc:selectedAccounts)

              {

                selectedrecordsIds.add(abc.id);    

              }

                   records = List<Contact>([SELECT Name FROM Contact WHERE AccountId IN : selectedrecordsIds ]);

              System.debug('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'+selectedrecordsIds);

          }

          

      //⌗⌗THIS IS WRAPPER CLASS

       // account and checkbox taken in wrapper class

       

       public class wrapaccount{

        

        public account accn{get;set;}

        public boolean isSelected{get;set;}

         

           public wrapaccount(account a){

         

             accn=a;
