Question

I’m using replace and replaceAll Java functions to replace strings in text files.

I’ve some issues with some symbols occurring in my text file, such as " and \

Let’s say I have to remove the ” from “blablabla”, what should i use ? I’m currently using this line but it doesn’t work:

fields[i] = fields[i].replaceAll("\\"blablabla\\"", "");

thanks

Answer 1

It’s because replaceAll uses regex, and in regex \ which is written as \\ in a Java String has a special meaning. Incidentally, that meaning is also to escape characters.

Use replace to avoid that, as replace only checks for simple equality. Also, it’s probably faster.
