JAVA ONLY
File Input and Output Chapter
1. It is a well-known phenomenon that most people are easily able to read a text whose words have two characters flipped, provided the first and last letter of each word are not changed.
*For example, I dn'ot gvie a dman for a man taht can olny sepll a wrod one way. (Mark Twain)
-Write a program with a method scramble(String word) that reads the contents of a file with a paragraph in it and constructs a scrambled version of the paragraph, randomly flipping two characters other than the first and last for all words greater than length 3.
2. A spreadsheet file can be stored as a comma separated file. For instance if a file called data.csv had the following in it:
name, quiz1, quiz2, quiz3, hw1, hw2, hw3, midterm, final
bill,8,9,10,50,45,43,88,93
jill,9,9,10,50,48,40,90,91
gill,6,5,7,38,22,40,70,73
will,8,9,9,40,45,43,83,94
totals,10,10,10,50,50,50,100,100
It would display in a program like Microsoft excel appropriately.
a) create a file called data.csv with this data on your hard drive.
b) read the file into a program calculating each students final percentage.
c) have the program write a new file with an extra column containing the final percentage for each student, a column heading for the first row, and the last row can end with 100 for its percentage.
