答
以下代码应将最后出现的 ',' 替换为 ')'.
The following code should replace the last occurrence of a ',' with a ')'.
StringBuilder b = new StringBuilder(yourString);
b.replace(yourString.lastIndexOf(","), yourString.lastIndexOf(",") + 1, ")" );
yourString = b.toString();
注意 如果 String 不包含 ','，这将抛出异常.
Note This will throw Exceptions if the String doesn't contain a ','.
