The only benefit of that code is that it confuses people reading practice questions for their cert exams. You should only use it in real life if you want to get sacked immediately The empty catch block won't get you sacked quite as quickly.
Pease start by telling us where the code comes from.
It is all about order of execution. I suggest you put something in the catch block to find out what sort of exception you might catch. Then go back to the code and work out the order of execution, remembering the rules are
1: Go left to right.
2: Evaluate subexpressions with higher precedence operators or in brackets before the whole expression can be completed.
Write down al the stages.
