Lab 1: First Program
## Overview
The purpose of this assignment is to ensure that all students are able
to create, compile, and run Java programs within the [IntelliJ IDEA](http://www.jetbrains.com/idea/) Integrated Development Environment (IDE).
### Prerequisites
* Download and install [Java 8 JDK (Java Development Kit) from Amazon (called Amazon Corretto 8)](https://docs.aws.amazon.com/corretto/latest/corretto-8-ug/windows-7-install.html) (select the .msi file of the Windows x64 JDK).
* Download and install [IntelliJ IDEA](http://www.jetbrains.com/idea/download/index.html). The Community Edition is all you'll need for this course, but you can download the Ultimate Edition and create a [free student account](https://www.jetbrains.com/student/), if you'd like.
## Part I
The following program asks the user for the number of credits s/he is taking
and the number of hours s/he plans to study each week. The program calculates
the recommended number of hours to study based on the number of credits and
compares that to the student's plan.

+ " credits this term and plan to study " + plannedHours
+ " hours per week.");
System.out.print("You plan to study ");
if(plannedHours < recommendedHoursLow) {
System.out.print("less than");
} else if(plannedHours > recommendedHoursHigh) {
System.out.print("more than");
} else {
System.out.print("in the range of");
}
System.out.println(" the recommended " + recommendedHoursLow + " - "
+ recommendedHoursHigh + " hours per week.");
}
}
```
Follow along as your instructor demonstrates how to create a project,
package, and class in IntelliJ. Then paste the above code into the text
editor window of IntelliJ.
## Part II
Once you have successfully compiled and run the program, create a new class
called `TruthsAndLie` and write a program that displays two true statements
about yourself and one lie about yourself. The program you write should be
much less complicated than the sample program above since you will not require
user input or do any calculations. Note: your program should just print the
three statements. It should not identify which statements are true and which
statement is a lie.
Select a partner, introduce yourselves and demonstrate your working programs.
If you need help getting your program to work, ask your partner for help. If
your partner needs help getting his/her program to work, assist them. Once
both of your programs compile and run successfully, have your partner guess
which of your statements is a lie.
Write both of your names on a sheet of paper and indicate how many guesses
it took to guess the lie. For example, if Jane Dough and Jon Doh were partners
and Jon guessed Jane's lie on the first guess and Jane guessed Jon's lie on
the second guess, your paper should look something like this:
<table>
<tr><th>Name</th><th>Number of guesses</th></tr>
<tr><td>Jane Dough</td><td>2 guesses</td></tr>
<tr><td>Jon Doh</td><td>1 guess</td></tr>
</table>
