ArrayList contains case sensitivity

Question

I am currently using the contains method belonging to the ArrayList class for making a search. Is there a way to make this search case insensitive in java? I found that in C

Answer 1

Looking at the Java API, there is no such method for contains.

But you could do at least two things:

1. Override the equals method in your ArrayList object with your own, or equalsIgnoreCase(str)

2. Write your own contains method, which should iterate through your ArrayList entities, and do a manual check.

   ArrayList list = new ArrayList();
   ...
   containsIgnoreCase("a", list);
   
   public boolean containsIgnoreCase(String str, ArrayList list){
       for(String i : list){
           if(i.equalsIgnoreCase(str))
               return true;
       }
       return false;
   }
