• Is there any reason to prefer UTF-16 over UTF-8?

  - by Oak

  Examining the attributes of UTF-16 and UTF-8, I can't find any reason to prefer UTF-16. However, checking out Java and C#, it looks like strings and chars there default to UTF-16. I was thinking that it might be for historic reasons, or perhaps for performance reasons, but couldn't find any information. Anyone knows why these languages chose UTF-16? And is there any valid reason for me to do that as well?

• Access modifiers in Object-Oriented Programming

  - by Imran

  I don't understand Access Modifiers in OOP. Why do we make for example in Java instance variables private and then use public getter and setter methods to access them? I mean what's the reasoning/logic behind this? You still get to the instance variable but why use setter and getter methods when you can just make your variables public? please excuse my ignorance as I am simply trying to understand why? Thank you in advance. ;-)

• How to compute the probability of a multi-class prediction using libsvm?

  - by Cuga

  I'm using libsvm and the documentation leads me to believe that there's a way to output the believed probability of an output classification's accuracy. Is this so? And if so, can anyone provide a clear example of how to do it in code? Currently, I'm using the Java libraries in the following manner SvmModel model = Svm.svm_train(problem, parameters); SvmNode x[] = getAnArrayOfSvmNodesForProblem(); double predictedValue = Svm.svm_predict(model, x);

• Should a Stack have a maximum size?

  - by Sotirios Delimanolis

  I'm practicing my knowledge of ADTs by implementing some data structures, even if most already exist. With Stacks, a lot of books and other documentation I've read talk about the stack throwing an error when you try to add an element but the stack is full. In a java implementation (or any other), should I specifically keep track of a maximum stack size (from constructor), check to see if that size is reached, and throw an overflow exception if it is? Or is not such a big deal?
