Something I discovered I like about C# are properties & String.Format.
Does something like String.Format from C# exist in Java?
C# ex:
Yes, the class in question is "MessageFormat":
http://download.oracle.com/javase/6/docs/api/java/text/MessageFormat.html
MessageFormat.Format("Your lucky numbers are: {0}, & {1}", myNum, myNumSq);
(Not sure if auto-boxing will work correctly in this case - you might need to convert the int to an Integer first)
