Actual Final

Question 1

IMPORTANT NOTE: Creating a File object DOES NOT create a corresponding file folder on your hard drive. (T!)

Answer 1

NOTE: No folder is created on the disk when this object is instantiated BUT…we could later actually create the directories on the disk by using methods such as mkdir() and mkdirs()

Question 2

Using getParentFile()

Answer 2

File fileOne = new File(“C:/temp34/myFile.txt”); fileOne.getParentFile().mkdirs(); //this builds the temp34 folder //now call createNewFile() fileOne.createNewFile(); //creates the empty .txt file in temp 34

Question 3

any exceptions of the UNCHECKED flavor the coder does not have to write any special code called “exception handling code” .

Answer 3

Options that are unchecked include the ArithmeticException and the ArrayIndexOutOfBoundsException.

Question 4

CONCEPT: A delimiter is a block of character(s) that separates words. WE DO NOT PRINT OUT THE DELIMITER character(s)

Answer 4

it takes as an argument something called a regular expression, which is a pattern of a set of character(s) inside a set of square brackets that it either looks for or ignores, depending on how you set it up

Question 5

Example: the regular expression [0-9]+ would be a delimiter that says “interpret any block of one or more digits as a delimiter and do not print it to the screen”.

Answer 5

Example 2: in the regular expression[^0-9]+, the “^” caret symbol would mean “DO NOT include any digits in the delimiter” , but ALL OTHER CHARACTERS would be considered to be part of the delimiter, so they would not be printed.

Question 6

One way to create a PrintWriter object is to call its constructor and pass it a file name: File

Answer 6

File myFile = new File(“output.txt”); Printwriter writer = new PrintWriter(myFile);
