The CSV (or comma-separated values) format is commonly used for tabular data. Each table row is a line, with columns separated by commas. Items may be enclosed in quotation marks, and they must be if they contain commas or quotation marks. Quotation marks inside quoted fields are doubled. Here is a line with four fields:

1729, San Francisco, "Hello, World", "He asked: ""Quo vadis?"""

JAVA CODE:

Implement a class CSVReader that reads a CSV file, and provide methods

int numberOfRows()

int numberOfFields(int row)

String field(int row, int column)

Use the attached CSV files “att2007.csv” and “quotes.csv” to test your program.

2. (Question P11.5 in the textbook, 30 points)

Using the attached CSV file “att2007.csv” and the CSVReader class from the above Question 2, read the data and compute a summary, such as the maximum, minimum, or average of one of the columns.
