If a method does not catch an exception,then it must at least warn programmers that any invocation of the method might possibly throw an exception.This warning is called a/an:

List five common examples of exceptions that occur.

Write a complete Java program that prompts the user for two nonnegative integer numbers.Your program should handle bad input data.

Define an exception class called DiskDriveNotReady.The class should have a constructor with no parameters.If an exception is thrown with this zero-argument constructor,getMessage should return "Disk Drive Not Ready!" The class should also have a constructor with a single parameter of type String.If an exception is thrown with this constructor,then getMessage returns the value that was used as an argument to the constructor.

Define an exception class called FileNotFoundException.The class should have a constructor with no parameters.If an exception is thrown with this zero-argument constructor,getMessage should return "File Not Found!" The class should also have a constructor with a single parameter of type String.If an exception is thrown with this constructor,then getMessage returns the value that was used as an argument to the constructor.

Methods that process String arguments as if they were numbers could possibly throw a/an _________ exception.

If a method throws an exception,and the exception is not caught inside the method,then the method invocation:

When using the Scanner class one should account for a/an:

All exceptions are descendants of the class:

The two most important things about an exception object are its type and the message that it carries in an instance variable of type String.

The basic way of handling exceptions in Java consists of the try-catch-throw trio.

An exception is caught in a _________ block.

Should an application catch objects of type Error?

ArrayIndexOutOfBoundsException is a descendent of the class RuntimeException.This means:
