Question

What is the difference between a text file and a binary file?
 Text files contain ASCII characters and binary files contain UNICODE characters 
 Text files contain are raw 8 bit bytes of 1's and 0's, binary files contain ASCII or UNICODE characters
 Text files contain ASCII or UNICODE characters and binary files are raw 8 bit bytes of 1's and 0's


What is the advantage of a relative file path name over an absolute file path name?
 Programs using relative path names do not care what directory the program is running from.
 Programs using relative path names are easier to move to new and/or different computers.
 Programs using relative path names specify the FULL path to a file, absolute paths are partial.


Which answer is ALL true regarding a File object:? 
 It can tell you if a file exists, tell you the length of a file, it can tell you if the path is a directory
 It can tell you if a file exist, can write a text file to disk, it can indicate if the path is a directory
 It can tell you if a file exist, tell you the length of a file, it can read and write to a file.
 It can read a text file from disk, tell you the length of a file, it can indicate if the path is a directory


Reading and writing text files using Java is easy because:
 Writing files is just like using Scanner object and reading files is just like using System.out.
 The PrintWriter and Scanner objects are automatically created for you.
 Writing files is just like using System.out and reading files is just like using a Scanner object.
 The PrintWriter and Scanner objects are the ONLY objects needed.


Which answer best describes the try-catch statements? 
 try-catch are exception handling statements that let the programmer control what happens when a problem occurs.
 try-catch are exception handling statements that let the JVM control what happens when a problem occurs.
 try-catch are exception objects that let the programmer control what happens when a problem occurs.

Answer

A binary file is a computer file which may contain any type of data, encoded in binary form for computer storage and processing purposes; for example, computer document files containing formatted text. Many binary file formats contain parts that can be interpreted as text; binary files that contain only textual data - without, for example, any formatting information - are called plain text files. In many cases, plain text files are considered to be different from binary files because binary files are made up of more than just plain text. When downloading, a completely functional program without any installer is also often called program binary, or binaries (as opposed to the source code).

A text file (sometimes spelled "textfile") is a generic description of a kind of computer file in a computer file system.
[1] At this generic level of description, there are two kinds of computer files: 1) text files; and 2) binary files.
[2] This broad two-level distinction is widely recognized and applied in computing, even though it can be misleading,
and subject to differing interpretation
