All of the exceptions you will handle are instances of classes that extend the __________ class.

Exception

Which of the following statements is true?

The code in a finally is executed whether an exception is handled or not.

What happens if a program does not handle an unchecked exception?

The program is halted and the default exception handler handles the exception

All exceptions are instances of classes that extend the __________ class.

Throwable

Chained exceptions are useful for finding out about ________.

an original exception that was caught before the current exception was thrown

Which of the following are types of assertions?

control proceeds to the first statement after the finally block

A new exception class must directly extend the Exception class.

false

The throw statement informs the compiler that a method throws one or more exceptions.

false

When handling exceptions, you can use a [fillIn1] reference as a [fillIn2] in the catch clause. [fillIn3] means to take on many forms that in OOP is the result of [fillIn4] where one class is related to another class. True or False: A parent/superclass reference variable can be used in referencing their children/subclass objects. [fillIn5]

fillin1: polymorphic fillin2: parameter fillin3: Polymorphism fillin4: inheritance fillin5: True

Code can be written to throw [fillIn1] or [fillIn2]. The throw statement is used to [fillIn3] throw an exception. Insert Format: [fillIn4] Code a throw statement with this message: "No such employee!" Insert Code: [fillIn5]

fillin1: standard Java exceptions fillin2: custom exceptions fillin3: manually fillin4: throw new ExceptionType(MessageString); fillin5: throw new Exception("No such employee!");

In a catch requirement, the code that generates the exception must be wrapped in a [fillIn1] block and must provide a [fillIn2] handler for the checked-exception type (or one of its superclasses). In a declare requirement, the method must provide a [fillIn3] clause containing the checked-exception type after its parameter list and before its method body.

fillin1: try fillin2: catch fillin3: throws

When you write a method that throws a checked exception, you must

have a throws clause in the method header

When an exception occurs, it is said to have been ________.

thrown

The ability to catch multiple types of exceptions with a single catch clause is known as multi-catch and was introduced in Java 7.
