Hi there I’am tryinig to remove two o more words in a String with the replaceAll method in Java
but I am not good in regex at all and I have not been able to do it.
So here is the code:
public static void main(String[] args) {
String s= "@class::menu-select @id::calibration-content";
System.out.println(s.replaceAll("[(@class::)(@id::)]",""));
}
But when I run this what I get is the following text menu-eet brton-ontent
BTW the words I am trying to remove are @class:: and @id::
Does anyone knows how to do this ? ¡Thanks in advance!
>Solution :
String#replaceAll accepts a regular expression, and you’re passing it a character class of substrings you’re looking to replace, which isn’t correct.
Instead, you could change the regular expression to look specifically for the substrings:
System.out.println(s.replaceAll("@class::|@id::",""));
This results in the following output:
menu-select calibration-content
Keep in mind that there are more efficient methods of removing substrings from a String than regex.
