You can catch all exceptions by catching the superclass Exception.
try {
// Do some wacky stuff
} catch (Exception e) {
System.out.println("I've gone nuts");
e.printStackTrace();
}
Yes, it does. The child exceptions classes must always be caught first and the "Exception" class should be caught last
In Java there are two main types of Exceptions. * Checked Exceptions - The ones that can be checked & handled in our code. Ex: I/O Exception, SQL Exception etc. In most cases, the compiler itself forces us to catch & handle these exceptions * Un-checked Exceptions - The ones that we cannot & should not handle in our code. Ex. Null Pointer Exception The java.lang.Throwable is the super class of all errors and exceptions in Java. Only objects of this class can be thrown & caught and handled by try-catch blocks. Ex: try { ..... ..... } catch (Exception e){ ... } finally { ... }
Deferred exception handling refers to a programming design pattern where individual class level methods do not handle exceptions using try catch blocks. They just cascade the exceptions to the calling methods using the "throw" keyword and all exceptions are handled centrally in one place. This is called deferred exception handling where the exceptions are deferred in the place where they occur and propagated to a parent class which handles it.
There is no catch block that names either the class of exception that has been thrown or a class of exception that is a parent class of the one that has been thrown, then the exception is considered to be unhandled, in such condition the execution leaves the method directly as if no try has been executed
Yes it can. It is preferable to have code that will handle these exceptions in every class rather than throwing random exceptions that might confuse the user of the system

import java.lang.Exception, the Exception class.
Define the exception. Throw it when the exception is detected. class My_Exception {}; // definition void f () { if (some_error) throw My_Exception; } int main () { try { f(); } catch (const My_Exception& err) { // ... } }
No it cannot throw, except for the subclasses of the exceptions thrown by the parent class's method

I wouldn't be caught dead in sleeping during the class.
Truancy is an act when you skip class/school.If you get caught you will be taken to school/class
A fly is an invertebrate. All of them. No exceptions.
Only if you don't get caught...
