Singleton Pattern: Additional Interest 2003-12-17 - By Kancharlapalli,Sridhar
Back
The main purpose of singleton is to restrict the number of object instances
been created.
"Math class is an example of Static-Singleton", this strategy has it's own
drawbacks as it can't be extended. So, it is best suitable for utility classes.
Main purpose of making this class a Static-Singleton is for better memory
management.

I don't understand your question... Singleton pattern doesn't have all
methods static, but only one (getInstance()). The Math class is an
utility class ,not a (GoF) pattern.
