**This question must be done using Java Eclipse** (Assignment) Write a zip code lookup program. Read a data set of 1,000+ zip codes and city names from a file that contains zip codes and city names in Iowa in random order. Handle lookups by zip code and also reverse lookups by city name. Use a binary search for both lookups. Four files are provided with the assignment. I will post them below. 1. ZipLookup.java: class containing ma in method. No modification needed. 2. Item.java: class to store an item. Use string variable ‘key’ for zip code and string variable ‘value’ for city name. No modification needed. 3. LookupTable.java: core class of this assignment. Complete all methods. 4. iazip.txt: zip codes and city names in Iowa. Thank You! **Look upTable.java import java. util. Array List; java. util. Collections; import java. util.
