I have been trying to figure out how to use JProfiler.The manual is too big, too confusing and I don't know where to start. I just want to do a simple thing, i have written a very basic java program and i want to check how efficient it is.
I just want to know the following things in my program :
how much heap/stack memory each variable is taking
How much time its taking to execute a loop.
How much time it takes to execute a method.
How much heap memory my array is taking.
How much time it is taking to read/write to a file is taking.
Has the explicit casting that i use in my program making any difference or not .
I could not find any tutorials for Jprofiler.
Someone please guide me in the right direction.
