Find first Non repeating char in a String

Given a string, return the first NON-repeating character that occurs in the string. EX: “adzbdcab” returns ‘z’.


public class StringHandler {

    public static void main(String[] args) {

        String input = "adzbdcab";
        char[] inputCharArray = input.toCharArray();
        for (char inputChar : inputCharArray) {
            if (input.indexOf(inputChar) == input.lastIndexOf(inputChar)) {
                System.out.println("First NON-repeating character is " + inputChar);
                break;
            }
        }

    }
}
