Check06E (TS = 60)

Download the jar file typex.jar (the file has been updated on November 8, noon) and save it in the same directory as type.jar. typex.jar should already be part of your CLASSPATH.

Create the program named Check06E that prompts the user by printing

Enter file name:

The file name should be entered on the same line (see sample run below). You may assume that the user always enters the name of an existing file. You may also assume that the file has the same structure as the file named 2009.html which can be found here. It is an HTML file containing the gold prices for 2009. Your program should determine the highest gold price during the year and the date at which gold reached this highest price (ties are broken by the date earlier in the year). The exact way this output has to be produced can be found in the sample below.

Next, some hints are provided.

To extract the year from the file name, the methods indexOf and substring of the class String might be useful.
To read the content of the file, the classes File and Scanner might be useful.
It might be useful to skip those lines of the file until a line containing table is encountered. The next two lines can be skipped as well.
It might be useful to process lines of the file in groups of four lines.
It might be useful to skip those lines following the next line containing table.
To extract information from each group of four lines, the method split of the class String might be useful.
The methods indexOf and substring of the class String might be useful for extracting the dates. The class SimpleDateFormat might be useful for parsing the dates.
The methods indexOf and substring of the class String might be useful for extracting the prices. The class Double might be useful for parsing the prices.

Here is a sample run (where the user has entered 2009.html)

Enter file name: 2009.html
In the year 2009, gold reached its highest price of 1,220.20 on 12/02/09
