Answer / anonymous
String is immutable whereas StringBuffer and StringBuilder
can change their values.
The only difference between StringBuffer and StringBuilder
is that StringBuilder is unsynchronized whereas
StringBuffer is synchronized. So when the application needs
to be run only in a single thread then it is better to use
StringBuilder. StringBuilder is more efficient than
StringBuffer.
Criteria to choose among String, StringBuffer and
StringBuilder
If your text is not going to change use a string Class
because a String object is immutable.
If your text can change and will only be accessed from a
single thread, use a StringBuilder because StringBuilder is
unsynchronized.
If your text can changes, and will be accessed from
multiple threads, use a StringBuffer because StringBuffer
is synchronous.
