what is the differences between string and string builder??
StringBuilder has some extra options, like StringBuilder.append(String); They're both the same, regarding speed.
I recomend you to google around for such simple questions, that saves your time too, take a look on how many hits you will receive when you search for them. ;)Quote:

Actually, if you are building a String using all, or at least mostly, String literals, then simple String and + is faster (as most, if not all, of those operations will be optimized away by the compiler). However, if you are doing alot of String manipulation actions (additions, insertions, modifications, etc, etc) then StringBuilder is faster (not String Buffer as that is "thread-safe", so there is a lot of unnecessary syncs if threadedness doesn't factor into it's use in that situation).Quote:

I suggest you to read this Difference b/w String, StringBuffer and StringBuilder - Performance (Java in General (beginner) forum at JavaRanch)Quote:

Strings are immutable, while StringBuliders(StringBuffers also) are mutable. That means you can change the value.
Similar option is available for String objects as well. concat(String)Quote:
