Create a Java program. You have a list of Student ID's followed by the course number(separated by aa space) that the student is enrolled in. The listing is in no particular order. For eg. is student 1 is in CS100 and CS200 while student 2 is in CS105 and MATH210 then the list may 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(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> students = new HashMap>(); 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.
