Hello, my problem is:


String str1 = new String("                    ");          // length 20
String str2 = new String("test");                        // length 4

Which is the  fastest  way to copy str2 to str1 from postion 10 ?
(for example: str1 = "         test       ")

Thanks in advance,
Apostolis

Just to be completely clear... Strings are immutable, so what you are 
attempting to do is not altering str1, but creating a new String (which 
can be assigned to str1 if you want) with the desired contents.

Look at the API for String, and for StringBuffer.  If you are using JDK 
5, then also look at StringBuilder.
