Java: 设法取代[闭门]
原标题:Java: String replace doesn t find [closed]

我的言辞,在案文中找不到一切,例如:

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

I veeck the str and the replace, but取而代之 <代码>str完全取代其中的示意图。

因此,为什么不取代!

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

这意味着你的法典基本运作。 但你所取代的扼杀并非完全在你的消息来源中。

或许是因为你的假设是错误的。

可能不同于(湿)面积,或不同的代码(0x20或0xa0),或“tab11”
