Question
This is java,
I need a loop that will print basically the indivaul minutes of each players session I have most of the coding done already this is just the last part.
Here is the question
Each year, elementary school kids must keep track of the number of minutes they practice their band instrument each week. This ensures that they continue progressing with their instrument and become musicians. In this program, you are to create an application that shows the sum total of the minutes practiced 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, MinutesPracticed.txt contains the minutes practiced 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 Practiced
Name Minutes Practiced
Sammy Hagger 65
Nick Jonas 1001
…
------------------------------------------------------
Individual Minutes Practiced
Name Minutes Practiced
Sammy Hagger 35
Sammy Hagger 30
Nick Jonas 500
Nick Jonas 5001
…
