Title
Body
I am using PMD to analyze code and it produces a few high priority warnings which I do not know how to fix. 1) Avoid if(x!=y)..; else...; But what should I do if I need this logic? That is, I do need to check if x!=y ? How can I refactor it? 2) Use explicit scoping instead of the default package private level. But the class is indeed used only within the package. What access modifier should I use? 3) Parameter is not assigned and could be declared final. Should I add final keyword to all the places which PMD pointed out with this warning?
