    Default Help with this java program

    I was wondering if you guys could help me with this program, as i got absolutely no clue how to do it. I'm a fast learner so if i see how its done i know i'll get it immediately... so if you can help me, that would be great.

    "develop a Java application that will determine the average for each of the three students. You are given a list of the students IDs, firtsnames, lastnames and three quizzes. Your program should input the information for each student from the keyboard"

    Create a class called Student that includes six pieces of information as instance variables, a student Id. (type int), a firstname (type String), a lastname (type String), quiz1 (type int) quiz2 (type int) and quiz 3 (type int). Your class should have a constructor that initializes six instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. In addition provide a (quiz1+quiz2+quiz3 and average). Write a test application named StudentTest that demonstrates class Student's capabilities


    thanks in advanced guys
