Java question: A text file called names.txt contains one name per line, e.g., Allison John William John etc. Names can be duplicated in the file. Write the code that: 1.      Reads the names line by line. 2.      Stores each name and the number of times the name appears in one collection. 3.    Prints the number of different names to the console. 4.      Prints the names and how many times each name appears on the console. Think about what data structure would work in associating each name with the number of times it appears in the file. You do not need to write imports.

Since they have all sorts of applications, knowing their differences is a good place to start.
