You are to complete the class called GroceryCart.
which will read the items and then print: the name, the price, the quantity, and the extended price. Extended price is the quantity * the price. Use printf (page 530 section 11.2.9) to format the output so that it is displayed in columns. The column with the name will be 20 characters wide an left justified. Each of the numbers will 8 characters wide and right justified. Price and extended price should have 2 decimal places.

tofu 1.75 2 3.50
dried chilies 1.05 5 5.25

Write a program CEOSalaries to print a list which contains the ticker symbol, colon space, the name of the CEO, space, and the salary printed with a $ and comma separators. Use printf. The first record looks like this
VRX: J. Michael Pearson $143,077,442
After all the records are printed, print: "Average salary: " and then the average salary with a $ and comma separators and 2 decimal places.
Note: You need to remove the $ and commas before using Integer.parseInt to convert a strings to an int.
The file name will be provided in the command line arguments. This will tell you how to use command line arguments in Eclipse.
Catch the exception if the file does not exist and print this message: No such file: filename
To process data in a file, you have to exam the file to determine the format of the data. In this case, the name of the CEO can be either two or three words. Company names also varies in length. If the CEO name has three parts, one will be an initial, (like J. in the first entry). The initial may be either the first or the second name. Notice that the last name is the third name from the end

The United States Social Security Administration keeps lists of the most popular baby names by year and by decade. We have two list:, one from the 1900 to 1909 and one 100 years later from the 2000 to 2009. Each contains the top names for the decade. We want to know what names from the 1900s were still popular in the 2000s.
Write an application called BabyNames1900sAnd2000s to print two columns in alphabetical order. The first column will contain all the boys names for 1900s that were still popular in 2000s. The second column will contain all the girls names for 1900s that were still popular in 2000s. Make the columns 30 characters wide and left justified.
