CSIT 105 Foundations of Computer Science

Getting a jump on the Fall 2022 Semester

The online class begins 9/14, but if you wanted to get a jump on the material, here's a start.

A possible approach...

1. peek at the slides and overview for Chapter 1
2. download and install the Java JDK and NetBeans software
3. do Lab 1 Hello World
4. Peek at the first group of slides from Chapter 2 that explains the Hello World file
5. download the Ch 2 demo files and open in NetBeans ( see note below on TripCalculator.java and Payroll.java )
6. ^^^ getting that far is fantastic as a way to prepare for the course. Look at the rest of Chapter 2 only if you are comfortable with it.

Software

See Downloading and Installing the Software

Material - 1st two chapters

Chapter 1 - Introduction

Don't get bogged down with all of the terms, just focus on these High Level ideas:

• A program is a series of instructions that tell the CPU what to do
• An algorithm is a series of steps to solve a problem
• Programming Languages use keywords and when programming in a language, the programmer must follow the syntax rules
• A compiler is a program that translates source code into an executable form
• A "true compiler" translates source code into machine code. Java is not a "true compiler"
• Java Compiler translates .java code into .class file that contains bytecodes
• Java Virtual Machine (JVM) interprets bytecodes

Slides: Slides for Chapter 1

Lab 01 - Hello World

Don't feel you need to know what your typing ( that will happen in a later chapter ) - Point of Lab is just to use the NetBeans editor

Lab 1 Sheet: Using Hello World to test the Java JDK / NetBeans 14 Installation

Chapter 2 - Java Fundamentals

The focus is on the fundamentals of the Language - The chapter/slides begin by explaining the commands from Lab 1

Slides: Slides for Chapter 2

Demo files from slides that accompany Ch 2: CSIT105DemoChapter02F22.zip

extract the CSIT105DemoChapter02F22 folder from inside the .zip file into the NetBeansProjects folder

in class, two of the first files I demo are TripCalculator.java and Payroll.java - they both:

• get input from the user
• calculate something
• display results

Playing a video game that harmlessly launches bunnies? When you hit the button it triggers a piece of code...it may need to get data ( what level are we on...does the bunny launcher have bunnies...where is the bunny launcher aimed ) then after showing the bunny, in a loop - calculate new position - display bunny.
(No bunnies were harmed in this example.)
