The file United States.txt provides data on the 50 states. Each record contains 5 pieces of information about a single state: name, abbreviation, date it entered the union, land area (in square miles) and population in the year 2015. The records are ordered by the date of entry into the union. The first three lines of the file are: Delaware, DE, 12/7/1787, 1954, 941875 Pennsylvania, PA, 12/12/1787, 44817, 12856989 New Jersey, NJ, 12/18/1787, 7417, 8969545 U.S. States. Create a class State with five properties to hold the information about a single state and a method that calculates the density (poeple per square mile) of the state. The book I'm using is An introduction to Programing Using Visual Basic. Tenth Edition. I need this to work on Visual Studio 2015.
