Java在字符串中查找需要的字段 博客分类： SorLib

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;
		}
