Replace character in StringBuilder [duplicate]

Question

I have a StringBuilder and want to use replace method for a character. code given below

StringBuilder sb = new StringBuilder();
sb.append("01-02-2013");

How can i replace '-' with '/' ?

Answer 1

If don't want to convert the StringBuilder to a String or you need to keep using it/preserve it, then you could do something like this...

for (int index = 0; index < sb.length(); index++) {
    if (sb.charAt(index) == '-') {
        sb.setCharAt(index, '/');
    }
}

If you don't care then you could do something like...

String value = sb.toString().replace("-", "/");
