Exception is coverable
Error is uncoverable

Exception can be handled
and Error can not be handled

Exceptio is an run time error when an abnormal condition is
occured the jvm detect it and make the object of that
abnormal condition and throws it to its own class and that
object is catched by catched block and catch block handled it

Error is the compile time error not runtime and it is not
covered it is only fixed by a programer.

Note
When Error occur then our programe stops and donot run

but If exception occur then nothing happining only try block
will be suspended and after that if any code is written that
will be executed properly means our system or programe work
properly.

Is there any way to find whether software installed in the system is registered by just providing the .exe file? I have tried the following code but its just displaying the directory structure in the registry. Here the code : package com.msi.intaller; import java.util.Iterator; import ca.beq.util.win32.registry.RegistryKey; import ca.beq.util.win32.registry.RootKey; public class RegistryFinder { public static void main(String... args) throws Exception { RegistryKey.initialize(RegistryFinder.class.getResource("jRe gistryKey.dll").getFile()); RegistryKey key = new RegistryKey(RootKey.HKLM, "Software\\ODBC"); for (Iterator subkeys = key.subkeys(); subkeys.hasNext();) { RegistryKey subkey = subkeys.next(); System.out.println(subkey.getName()); // You need to check here if there's anything which matches "Mozilla FireFox". } } }
