Taking part of a char array and putting it into a string

So, I currently have a char array of 2000 chars. I will have 24 or less chars in the middle of this array that I need turned into a string. I have no ideas how to do this after many logic combinations and Google searches. Any help is appreciated!

String provides a constructor designed specifically for this task:

char[] bigData = ...
int startIndex = ...
int len = ...
String res = new String(bigData, startIndex, length);

startIndex represents the position in the array of characters where your string should begin; len represents the number of characters to take.

If char[] a = {'a','b','c','d'} then new String(a,1,2) will make "bc"
