Example Programs using Set, Apex & Visual force

Example Programs using Set, Apex & Visual force 

Write an apex class to add list of elements to set 

Public class set example 
     { 
Public set <string> name {get; set;}; 
Public set example () 
     { 
List <string> my list = new list <string> ()
My list. add (‘sushi’); 
My list. add (‘sushi’);
My list. add (‘Rakesh’);
My list. add (‘Rakesh’); 
names = new set <string> (); 
names. add (‘one’); 
names. add (‘two’);
names. add (‘one’);
names. add (‘one’);
names. add (my list);
           }
     }

Public void retains all (list) // this will keep only the values that are existing in list and set. 
Remove rest of the value. 
Public class set example 
 {
Public set <string> names {get; set;};
Public Boolean test {get; set;}
Public set example ()
            {
               List <string> my list = new list <string>(); 
Mylist.add(‘sashi’);
Mylist.add(‘ram’);
Mylist.add(‘kumar’);
test = names.retainAll(mylist);
}
}

Visual force Page : 

<apex:page controller = “setExample”>
<apex:pageBlock>
<apex:datalist value =”{!names}” var =”a”>{!a}
</apex: datalist>
</apex: pageBlock>
</apex:page>
