Catching Runtime Exception

Question

Is it good practice to catch High level Exception in the try block, this would also catch RuntimeException. My personal opinion is not to catch the Runtime Exception and let the JVM handle it. However if there is a need to catch specific Runtime Exception, code should be written for that.
try
// Your code
catch (Exception e)
e.printStackTrace()
}

Answer 1

I agree that runtime exceptions should generally not
be caught as they are mistakes of programmers.
But in order to debug a large project with hundreds of
classes it can be useful to do that anyways.
Any my big question is: how?
I tried to wrap the content of the main method in a
try / catch block hoping that I could catch all
exceptions not handled somewhere else.
But it didn't work.
I manually threw some exceptions somewhere in my GUI
and the main method wrapper didn't get them.
But the VM did and printed the exception message.
But I didn't want the VM to catch my exceptions. I
wanted to catch them myself at the lowest possible
point in my own classes.
And I thought that was the main method.
Can anyone help me?

P.S. please excuse my improvable english; it's not my
mother tongue.AWT uses many different threads in your program that you never find out about unless something breaks. main(String arg[]) starts as the lowest possible point but, if you construct a Frame, Image, or certain other objects from the AWT package, AWT Threads automatically start over which you have little or no control.
Overall, I don't think it's actually possible to catch the Runtime Exceptions out of these Threads. The best this you can do about them is prevent them from happening.
