Java:找不到字符串替换 [英] Java: String replace doesn't find

问题描述

mystring.replace() 没有在我的文本中找到所有内容，例如:

mystring.replace() doesn't find everything in my text e.g:

replace = (CalendarInfo.Monday + " " + String.valueOf(dayofmonth) + " " + String.valueOf(CalendarInfo.Month[monthofyear]).toString());
                   str= str.replace(replace, "Hello");

我已经检查了 str 和 replace 但替换仍然没有做任何事情！str 里面完全有替换字符串.

I've check the str and the replace but replace still doesn't do anything! str totally have replace string in it.

那为什么不替换替换！?

So why doesn't replace replace!?

推荐答案

String str = "abcd".replace("ab", ""); //str is "cd"

这意味着您的代码基本有效.但是您的替换字符串并不完全在您的源字符串中.

That means your code works basically. But your replace string is not exactly in your source string.
