Replace All method in Strings

Question

I want to replace a character in string with the replace all method, but this method gives me still the same string.

String example = "5x";
example.replaceAll(Character.toString('x') , Integer.toString(1));

What is wrong with the code?

You are right, I was just in a hurry. I will keep in mind for next time — fjoralba, Apr 14 '16 at 18:48

String is immutable. You should do something like

example = example.replaceAll(Character.toString('x') , Integer.toString(1));

Strings are immutable, meaning they can not be changed.

This can be done simply like this:

String example = "5x";
example = example.replaceAll("x", Integer.toString(1));

You are missing assigning the new string to example.
