CS 140 - Homework 8 - Due March 5

Reread pages 19-28 on Java basics.

In this homework we're going to write a simple Java program to calculate your current average in this course and then print it as a percentage. You should be keeping track of how many labs and homeworks you have completed and the grade earned. If you have not been keeping track start today. Send me an e-mail asking for the info if you don't have it. You program and main class should be named HW8.

1. Declare an appropriately typed variable named hw_avg to hold your current homework average. We have had seven homeworks to date. Give yourself zero points if you didn't turn an assignment in, one point for a check minus, and two points for a check. That implies the total number of possible homework points to date is 14. Print your home workaverage nicely as a percentage. For example

   		Homework average is 85%. 
   		

2. Declare a vaiable lab_avg and calculate your lab average and then print a nice message.

   We have had eleven labs to date. You get two free attendance/lab misses in this class. Give your self one point for a completed lab, and 1.5 points for a lab done with extra credit. Here are some examples:

   • Lets say you have missed one class and done ten of the eleven labs w/o any extra credit. Your lab average is then ten for ten or 100%.
   • If you have not completed four labs then your lab average would normally be 7/11; however two of the eleven are free misses so your average is 7/9 or 78%.
   • If you have completed ten labs with four getting extra credit then your avergage is (4*1.5 + 6)/10 or 120%.
3. Calculate your exam average. We have had one exam and one quiz with a total of 124 points. If you had a 16 on the quiz and an 75 on the exam then your exam average is (16 + 75)/124 or 73%.
4. Now compute your overall class average and print it. Recall from the syllabus that exams and quizzes are worth 60% of your grade, in class labs are 20% and HW is 20%. Print a nice message that says what your overall average is. For example:

   My class average is 82%
   

Example output

Your program's final output should look something like

Homework average is 75%
Lab average is 98%
Exam average is 90%
Overall average is 88.6%

What to turn in

1. Turn in a prinout of your program with your name on it.
2. e-mail me your program as an attachment with the subject heading CS140 HW 8.
