How do I break down a problem and solve it with the use of Java programming?
Alright, that makes sense. Can you recommend any useful Java libraries that could help with this problem?
Sure, one library that you could use is the Apache Commons Math library. It has a number of useful functions for calculating statistics, including mean and variance. Also, the Java Math library has some basic math functions that you could use as well.
