    Default Help with implementation of the DataSet class

    Hello, im having trouble completing a question in my big java book 2nd edition by Kay Horstmann.

    The question is this:

    Define a class Quiz that implements the Measurable interface. A quiz has a score and a letter grade (such as B+). Use the first implementation of the DataSet class to process a collection of quizzes.

    Display the average score and the quiz with the highest score (both letter grade and score).

    I know how to implement the measurable interface but im having trouble figuring out the rest.
    I know this may seem like an easy question to you guys but any help is greatly appreciated.
    Thanks.

    The DataSet interface is designed to receive information from an SQL query
    so unless you know SQL, You'd be lost.
    I don't know sql, but I can suggest you post this question again in the sql forum.
    if your problem only stems from not knowing how to implement DataSet, I suggest you view the page

    Greetings.
