**THIS IS A JAVA PROBLEM, NEEDS TO BE DONE WITH ECLIPSE!** 1 java file, Apendix a,b,c are given.
Complete the program that shows (i) zip codes given a city and (ii) city given a zip code at the URL http://www.melissadata.com/lookups/zipcityphone.asp. In the web site: (1) When you enter a zip code, the URL returns a page with information about the zip code (city, state, population, and number of business, etc. in the zip code). For example, if you enter 50011, the returned page is http://www.melissadata.com/lookups/ZipCityPhone.asp?InData=50011 and you can check the corresponding city is Ames, IA. (2) When you enter a city name (and a state name), the URL returns a page with information about the city (list of zip codes, are codes, etc.). For example, if you enter Ames IA, the return page is http://www.melissadata.com/lookups/ZipCityPhone.asp?InData=ames+ia and you can check the list of zip codes and area codes in Ames, IA.
In the program, use the menu of ZipLookup.java. In other words, ask the user to select (i) lookup by zip, (ii) by city, (iii) or quit. You can assume user will give five digits for lookup by zip code, and city and state (abbreviated) names for lookup by city. Unlike Homework 6, your program should list all zip codes for lookup by city.
After user selects a menu, send the request to the server using the URLConnection. Get the information needed from the HTML in the web page. In Appendices A and B at the end of this document, screenshot and sample HTML codes are attached for lookup by zip (Appendix A) and lookup by city (Appendix B).
In Appendix C, a sample run of the program is attached. Use the provided Incomplete source code (ZipLookupWeb.java) as a starting point. In modifying the source file,1. Do not change the file (class) names and method names. Points will be deducted if you have different names. 2. Fill in your name in the @author section of the comment in each of the files. If you do not, points will be deducted. Submit your work to Canvas. Make sure to submit source file (*.java). Class file (*.class) will not be graded and receive zero credit.
