Array contains() without case sensitive lookup? [duplicate]

Answer 1

it will require you to write your own contains() method. pointers for custom contains():

1. iterate over all the elements in the list.
2. compare the parameter string with all the values in

3. to make comparison case-insensitive be sure to apply any of toLowerCase or toUpperCase on BOTH parameter and the current element.

   List list; public boolean contains(String str){

      for(int i=0;i
