belongs to those exceptions that can be thrown during the operation of the Java Virtual Machine (JVM). It is an unchecked exception; therefore, it does not need to be declared in a method's or a constructor's throws clause.
Exception propagation in Java - an exception is first thrown from the top of the stack and if it is not caught, it drops down the call stack to the previous method. After a method throws an exception, the runtime system attempts to find something to handle it. The set of possible "som...
