Question
What is difference between StringBuffer and StringBuilder?
Answers
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 StringBuffer and StringBuilder

• If your text can changes, and will be accessed from multiple threads, use a StringBuffer because StringBuffer is synchronous. .   Your Comment
