You have a list of student ID’s followed by the course number (separated by a space) that the student is enrolled in. The listing is in no particular order. For example, if student 1 is in CS100 and CS200 while student 2 is in CS 105 and MAT H210 then the list might look like this:

1 CS100

2 MATH210

2 CS105

1 CS200

Write a program that reads data in this format from the console. If the ID is -1 then stop inputting data. Use the HashMap class to map from an Integer (the student ID) to an ArrayList of type String that holds each class that the student is enrolled in. The declaration should look like this:

HashMap‹ Integer, ArrayList‹String›› students -
new HashMap ‹Integer, ArrayList‹String› ›();

After all data is input, iterate through the map and output the student ID and all classes stored in the vector for that student. The result should be a list of classes organized by student ID.
