Exam 10: Exceptions and Advanced File Io

When using the throw statement, if you don't pass a message to the exception object's constructor,

The RandomAccessFile class treats a file as a stream of

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

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

Classes that inherit from the Error class are for exceptions that are thrown when

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

A(n) __________ is an object that is generated in memory as the result of an error or an unexpected event.

The throws clause causes an exception to be thrown.

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

A class must implement the Serializable interface in order for the objects of the class to be serialized.

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

When an object is serialized, it is converted into a series of bytes that contain the object's data.

What will the following code display? String input = "99#7"; Int number; Try { Number = Integer.parseInt(input); } Catch(NumberFormatException ex) { Number = 0; } Catch(RuntimeException ex) { Number = 1; } Catch(Exception ex) { Number = -1; } System.out.println(number);

If a class has fields that are objects of other classes, those classes do not need to implement the Serializable interface to be serialized.

Unchecked exceptions are those that inherit from the

A file that contains raw binary data is known as a

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

When writing a string to a binary file or reading a string from a binary file, it is recommended that you use

In order for an object to be serialized, the class must implement the __________ interface.

In Java there are two categories of exceptions which are
