How to replace characters from a String?

Question

I have a small problem. My application receives a numeric string representing a value from the server. But the server sends, for example "100.00" and I need to put a comma in place of that point.

100.00 => 100,00

I would like to know how to do this in the simplest way possible. I’ve looked around for tutorials that didn’t help me.

Answer 1

A "simple" option is to use the method replace class String.

String valorComPonto = "100.00";
String valorComVirgula = valorComPonto.replace('.', ',');
