Question
This is java
Each year, elementary school kids must keep track of the number of minutes they read each week. This ensures that they continue progressing in their reading and become lifelong readers. In this program, you are to create an application that shows the sum total of the minutes read by each student. There are two files in which you are to read. The first one, Student2017.txt contains all the students. The second one, MinutesRead.txt contains the minutes read and the student id. You are to create a Student class that contains an ArrayList of all the minutes read for each student. The end user should be able to print out the individual minutes read by a student and the sum total of the minutes ready by a student. An example of output might be like this:
-----------------------------------------------------
Sum of Minutes Read
Name Minutes Read
Sammy Hagger 1,203
Nick Jonas 3,435
…
------------------------------------------------------
Individual Minutes Read
Name Minutes Read
Sammy Hagger 234
Sammy Hagger 345
Nick Jonas 948
Nick Jonas 232
…
