获得子串的最佳方法？

Question

是否有更优化的方法来获取以“，”结尾并以“。”结尾的子字符串。比这样？

if (paramsText != null)
   {
       while (paramsText.contains(","))
         {
            params.add(paramsText.substring(0, paramsText.indexOf(",")));
            paramsText = paramsText.substring(
                    paramsText.indexOf(",") + 1, paramsText.length());
         }

         params.add(paramsText);
   }

Answer 1

因为你实际上没有检查“。”你可以这样做：

String[] params = paramsText.split(",");

Answer 2

也许这样的事情适合你：

String str = "There is, a more optimal, way to obtain. subtrings which,"
           + "are separated by, and ended by. than this way.";

String[] substrings = str.split("\\s*[.,]\\s*");
for (String substr : substrings)
    System.out.println("\"" + substr + "\"");

<强>输出：

"There is"
"a more optimal"
"way to obtain"
"subtrings which"
"are separated by"
"and ended by"
"than this way"
