i have a duplicate list, and other list to check the duplicates.
code is correct, but need to check with the logic, can any one fix this issue please.
  //If i selected checkbox  A and B, i should get [false,true] //as A -letter is in the list.
//if selectd A, FALSE.
//if selectd B, TRUE.

public class test4 {

 public list<string>duplicatevalues{get;set;}
 public list<Wrapperclass>wraplist{get;set;}
 public list<boolean> Selectedbooleanlist{get;set;}
  public list<string>listSelectedNames{get;set;}
 public test4(){
 listSelectedNames = new list<string>();
  Selectedbooleanlist= new list<boolean>();
  duplicatevalues= new list<string>{'a','c'}; 
  wraplist = new list<Wrapperclass>();
        Wrapperclass   wf1 = new Wrapperclass();
                  wf1.selected=false;
                  wf1.name ='a';
                   wraplist.add(wf1);
        Wrapperclass   wf2 = new Wrapperclass();
                  wf2.selected=false;
                  wf2.name ='b';
               wraplist.add(wf2);
               
 }
   public void check(){
  Selectedbooleanlist.clear();
     for(wrapperclass wrap: wraplist){
      if(wrap.selected == true){
        listSelectedNames.add(wrap.name);
        //Selectedbooleanlist.add(wrap.selected);
        }  
      }
   
    for(String s1 : duplicatevalues){
    if(listSelectedNames.contains(s1)){
     boolean  sel = false;
     Selectedbooleanlist.add(sel);
     }
     }
   }
  
  public class Wrapperclass{
       public boolean selected{get;set;}
       public string Name{get;set;}
    }
