Java

right /prog/ i've never used a text board on here, so, here goes. I would like a small hand with some basic java programming. I am using the BlueJ environment.

Given two Strings s1 and s2 already defined as

String s1 = "SESQUIPEDALIANISM";
String s2 = "";

write a sequence of lines of java code that will make String s2 contain (only)
the letters number 3, 10 and 12 from s1
(e.g. if s1 was "piano"
s2 containing letters 1, 3 and 4 would make s2 = "pan").

I too lol'd. However, the faggot in >>19 got the "synchronization" aspect wrong, but using StringBuffer is a good idea because string are immutable (as in their would be 5 string allocated for the program). And even though these conditions are known at compile time I highly doubt any JVM or compiler would be smart enough to optimize that.

If you used immutable stings in .Net, it would optimize to not to the excessive allocations.
