CSC-111 HW2 Calculate Temperature, Dewpoint, or Relative Humidity

Due: Saturday, Sept 22, 11:59pm

Create a program that inputs the 3 sets of 2 inputs needed to calculate Actual Temperature, Dewpoint, and Relative Humidity. For instance, entering Actual Temperature and Dewpoint will calculate the corresponding Relative Humidity. Entering Actual Temperature and Relative Humidity, calculates Dewpoint. Finally, entering Dewpoint and Relative Humidity, allows calculation of Actual Temperature.

Use the Scanner class for your input. To be clear, you will submit just one program that will have a total of 6 input methods and 3 calculations and outputs.

Use this website: for the necessary formulas. That page also has a calculator, you can use to check your own calculations.

All the temperatures in the equations are based in Celcius.  We live in a Fahrenheit world.  Please input and output temperatures in Fahrenheit.

Your outputs should be neatly formatted and annotated. Output 3 decimal digits.

Note: Just use the topics discussed in chapter 2, or what was discussed in class.  No methods, loops, if statements should be coded.


References in the formulas to

  • exp(expr) is Math.exp(expr) in Java
  • ln(expr) is Math.log(expr) in Java

Supplemental Instruction (SI)

The college has a new program called Supplemental Instruction (SI). Through this program, you will have the opportunity to meet weekly with our SI Leader, who will provide weekly review sessions for all interested students. The Leader is a current student who has recently taken the course and done well. They will be in class with you every day, hearing what you hear, and reading what you read. During each review session, you will have a chance to get together with your classmates to compare notes, discuss concepts that might be confusing, review material for tests and quizzes, and ask any questions that you might have.

Sessions will begin the week of September 11th, and run through the end of the semester. You can attend as many review sessions as you like; each one will be different because you will have new material to discuss. SI sessions are informal – bring any notes you have, your textbook, or a classmate! By coming to these sessions, you will be able to develop a better understanding of the course content as well as more effective ways of learning.

If you are unable to attend the group session, but would like to meet with the SI Leader, you can set up an individual time to meet with them. You can let them know you would like to make an appointment with them when you see them in class, or feel free to send them a note through their college email.

I am thrilled that we have this new opportunity for you, and I am hopeful that you take advantage of this program.

Our SI leader is Joseph Santos and his email address is:

CSC-111 Homework 1

Due Tuesday, Sept 11  11:59pm.

This problem is on page 31 in the textbook.


Do this problem without using variables, loops, or anything beyond what is discussed in Chapter 1. You’ll have a better appreciation for these advanced tools once you do the problem without them.

You need to submit a gist link to of your code by the due date and time.



CSC-111 – Introduction to Java Programming for Online Learners

An optional resource but highly suggested supplement for this course.  I’ll be using this video series to supplement my lectures.  I’ll also be using the videos as the basis for an online Intro to Java course that will hopefully be running Spring 2019:

Udemy Course – Introduction to Java Programming for Online Learners

This course can be purchased for as little as $9.99.  Not bad!

Sign up for a GitHub Account

If you going to be a programmer, then github is a site you’ll need to use.

Go here: and create an account for yourself.  We will be using github for homework submissions.

In particular the part of github we’ll  be using is the gist function located here:

You can submit multi-file projects under just one URL! You also have a record of all your work in one convenient location.
