explain the difference between string builder and string buffer classes
Hi,
Here is my code
public static void main(String[] args) {
String s1 = "abc"; StringBuffer s2 = new StringBuffer(s1); StringBuffer s3
= s2; StringBuffer s4 = new StringBuffer(s1);
}
in this example how many objects are created ?
could you please explain.

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.
