Difference between using Throwable and Exception in a try catch

Question

Sometimes, I see

try {

} catch(Throwable e) {

}

And sometimes

try {

} catch(Exception e) {

}

What is

Answer 1

Throwable is super class of Exception as well as Error. In normal cases we should always catch sub-classes of Exception, so that the root cause doesn't get lost.

Only special cases where you see possibility of things going wrong which is not in control of your Java code, you should catch Error or Throwable.

I remember catching Throwable to flag that a native library is not loaded.
