Replace character ' in a string

Doesn't seem to work, searched the forum for other replace issues, but there are houndreds of results.

With the replaceAll() method, the first parameter is a regex string, and the second parameter is a regex replacement string. With both strings, the backslash has special meaning and needs to be escaped.

Another option is to use the replace() method instead -- which doesn't use regexes.

Tried:

Still no result.

Have you tried " replaceAll("'", "\"") " ?

Well nothing happens, the string isn't changed at all. My input is this string: "=C3+'C\"3+C3'" and I want to replace the ' with "
No exceptions. I have an array with that kind of strings and I tried the replace/replaceall method.

Show us some code please -- it would help us if you tell us how you are calling the method. For all we know, you could be doing something really silly like....

str.replace('\'', '\"');

Strings are immutable. String methods like replace(), replaceAll(), and even substring(), do not change the string value. They return a new string.

Of course, you know this, since you used substring() correctly.

Henry

Damn that was so obviously!

Thanks Henry!
