I need to replace a String which contains white space and periods. I have tried with the following code:
String customerName = "Mr. Raj Kumar";

我从第一个SOP获得了正确的客户名称,但是从第二个SOP我没有得到任何值。

推荐答案
转义点,否则它将匹配任何字符。这种转义是必要的,因为将第一个参数视为正则表达式。
escape the dot, or else it will match any character. This escaping is necessary, because replaceAll() treats the first paramter as a regular expression.
customerName = customerName.replaceAll("\\.", "");
你可以用一个陈述完成整个事情:
You can do the whole thing with one statement:
customerName = customerName.replaceAll("[\\s.]", "");
