The following code has been implemented: public class MarkRecord(){ public String name; public double mark; } public class CalculateStats{ public static void main(String args[]){ MarkStore myStore = new MarkStore(); myStore.makeNewRecord("Joe",55); myStore.makeNewRecord("Steve",83); myStore.makeNewRecord("James",61); double average = myStore.getAverageMark(); System.out.println(average); } } The MarkStore class uses a LinkedList object to store MarkRecords. The makeNewRecord method creates a new MarkRecord object using the pa- rameters it receives, and adds the newly created MarkRecord object to the LinkedList. The getAverageMark() method returns the average mark from all the MarkRecords in the LinkedList Implement (Write code for) the MarkStore class and all necessary methods.
