How can I add list values into set?
Suppose I've a list of fruits like
List<string> fruits = new List<string> {'mango','papaya','orange','mango'};
then how can I assign this values to set?
for(integer i =0; i<fruits.size(); i++)
{
set<string> fruits1 = fruits[i];
}
The above code declaration is correct?
List<string> fruits = new List<string> {'mango','papaya','orange','mango'};
then how can I assign this values to set?
for(integer i =0; i<fruits.size(); i++)
{
set<string> fruits1 = fruits[i];
}
The above code declaration is correct?
List<Integer> ls = new List<Integer>(); ls.add(1); ls.add(2); // Create a set based on a list Set<Integer> s1 = new Set<Integer>(ls); // Elements are copied from the list to this set System.debug(s1);// DEBUG|{1, 2}Above code will help you. More details

Once you got a List, just iterate it in a for-each loop and use .add method to add the elements in the set. For example you can add the elements of your List "Fruits" to set as :
set<String> setofFruits = new set<String>();
List<String> fruits = new List<String> {'mango','papaya','orange','mango'};
for(String str :fruits){
setofFruits.add(str);
}

You can assign the value of list to set by using predefine methods of Set.
List<string> fruits = new List<string> {'mango','papaya','orange','mango'}; Set<String> setFruits = new Set<String>(); setFruits.addAll(fruits );Please let me know if this helps you!
