正则表达式匹配问题

如何匹配下面这些字符串


"INDEX A ( B,C )"
"INDEX ( D,E )"

[brinado]

\"INDEX\s+A?\s+\(\s+[B|D]\,[C|E]\s+\)\s\"

[tedagov328281]

A只是举个例子，可以是任意字符串

[andnnl]

//		String str2 = "INDEX     A   (   B,C   )";
		String str2 = "INDEX     (   D,E   ) ";
		// String str= "[phone],[phone] ";
		String ptn = "INDEX\\s+[A-Za-z]?\\s+\\(\\s+[A-Za-z],[A-Za-z]\\s+\\)";
		
		Pattern p = Pattern.compile(ptn);
		Matcher m = p.matcher(str2);
		if (m.find()) {
			System.out.println("str:" + m.group());
		}

[andnnl]

		String str = "的2Y353k可能够354kv可#23DF快递22空手32dd3KV道2349在k590Kv";
		String ptn = "([a-zA-Z\\d]+(?=kv|KV|kV|Kv))|(\\d{3,})|([a-zA-Z\\d]{3,})";
		Pattern p = Pattern.compile(ptn);
		Matcher m = p.matcher(str);
		String result = "";
		while (m.find()) {
			result = m.group();
			System.out.println(m.group());
		}
