Match strings with regular expression in ignore case

Question

I need to match strings in my array which are not starting with "KB" string. I have tried this

String[] ar = {"KB_aaa","KB_BBB", "K_CCC", "!KBD", "kb_EEE", "FFFF"};
Pattern p = Pattern.compile("[^(^KB)].*");

for(String str : ar)
{
    Matcher m = p.matcher(str);
    if(m.matches())
         System.out.println(str);
}

But it still not matches "K_CCC". Thanks

    String[] ar = {"KB_aaa","KB_BBB", "K_CCC", "!KBD", "kb_EEE", "FFFF"};
    Pattern p = Pattern.compile("^KB.*", Pattern.CASE_INSENSITIVE);

    for(String str : ar)
    {
        Matcher m = p.matcher(str);
        if(!m.matches())
             System.out.println(str);
    }
