Description

Overview
• This lab exercise has two objectives
• 1) Updating your Java and Eclipse installations to Java 8, update 65, and Eclipse Mars
• 2) Reviewing topics from Introduction to Programming by creating a simple calculator

Tasks 1) Update Java JDK o Using the Windows Control Panel Un-install Java 7, this includes both the JDK and JRE o Locate and Delete your Eclipse folder (Note: This is not the workspace folder)
*** If in doubt make a back up copy of your workspace to a USB drive, or another folder on your hard drive and ask your professor for help***
o Download Java 8 update 65 from this link:
 http://www.oracle.com/technetwork/java/javase/downloads/index.html o Download Java 8 documentation from this link:
 http://www.oracle.com/technetwork/java/javase/downloads/index.html
 (This is the same link, scroll down in the web page just below “Additional Resources” o Download Eclipse Mars from this link:
 http://eclipse.org/downloads/

o Unzip the Eclipse folder and move it to a location of your choosing

Be prepared to show start up of Eclipse Mars, as well as use java –version, and javac –version in a console to the lab professor who will verify Java 8 and Eclipse Luna is installed.

2) Create a simple Calculator

Example of using the program, bolded highlighted digits are user input
Please enter an option:
1 Addition
2 Subtraction
3 Multiplication
4 Division
4
Please enter number 1:1
