Java在字符串中查寻需要的字段

Java在字符串中查找需要的字段
该方法可以将一段字符串中特定的字符取出：
例如：aaaaa[T]0909,[e],wer32[a],wrwerwe[asdfst]，
程序最终取出的字段是：Tea

String test = getTextFromClipboard();if (null == test) {return;}test = test.replaceAll("\\[", "%").replaceAll("\\]", "%");Pattern p = Pattern.compile("%[A-Za-z]{0,2}+[0-9]{0,2}%");Matcher matcher = p.matcher(test);String word = null;String[] keys = new String[3];int count = 0;while (matcher.find()) {word = matcher.group();keys[count++] = word.replaceAll("%", "");if (3 == count) {break;}}if (3 != count) {return;}
