Exam 11: Exceptions and Advanced File Io

When an exception is thrown by code in its try block, the JVM begins searching the try statement for a catch clause that can handle it and passes control of the program to __________.

The IllegalArgumentException class extends the RuntimeException class and is, therefore, __________.

A(n) __________ is a section of code that gracefully responds to exceptions when they are thrown.

To serialize an object and write it to the file, use the __________ method of the ObjectOutputStream class.

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

The catch clause __________.

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

An exception's default error message can be retrieved by using the __________ method.

A(n) __________ contains one or more statements that are executed and can potentially throw an exception.

If a method does not handle a possible checked exception, what must the method have?

Assume that the classes BlankISBN, NegativePrice, and NegativeNumberOrdered are exception classes that inherit from Exception. The following code is a constructor for the Book class. What must be true about any method that instantiates the Book class with this constructor? public Book(String ISBNOfBook, double priceOfBook, Int numberOrderedOfBook) { If (ISBNOfBook == "") Throw new BlankISBN(); If (priceOfBook < 0) Throw new NegativePrice(priceOfBook); If (numberedOrderedOfBook < 0) Throw new NegativeNumberOrdered(numberOrderedv); ISBN = ISBNOfBook; Price = priceOfBook; NumberedOrdered = numberOrderedOfBook; }

If your code does not handle an exception when it is thrown, __________ prints an error message and crashes the program.

In a catch statement, what does the following code do? System.out.println(e.getMessage());

To write data to a binary file, you create objects from which of the following classes?

In Java there are two categories of exceptions which are __________.

In the following code, assume that inputFile references a Scanner object that has been successfully used to open a file: double totalIncome = 0.0; While (inputFile.hasNext()) { Try { TotalIncome += inputFile.nextDouble(); } Catch(InputMismatchException e) { System.out.println("Non-numeric data encountered " + "in the file."); InputFile.nextLine(); } Finally { TotalIncome = 35.5; } } What will be the value of totalIncome after the following values are read from the file? 2)5 8)5 3)0 5)5 Abc 1)0

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

What will be the result of the following statements? FileInputStream fstream = new FileInputStream("Input.dat"); DataInputStream inFile = new DataInputStream(fstream);

If the class SerializedClass contains references to objects of other classes as fields, those classes must also implement the Serializable interface in order to be serialized.

To read data from a binary file, you create objects from which of the following classes?
