 Each variable is like a pad of sticky notes.  You can write on the front sheet, and when you want, you can rip that sheet off, and write something (possibly different) on the newly exposed sheet.  The variable name holds the information on the currently showing sticky note.

+Does order matter with the operands of an operator?  (the order of the items that are passed to the operator?)
 
 If we are only able to use integers for the above operations, what piece of information are we loosing when we store the answer back to an integer?  The operator to get this info with one step is the % operator.
 
 We have a special operator, it is the assignment operator.  This is the operator that removes the top sheet of the stickynote pad and writes a value on the next sheet.  In Java we will use a single equals sign to indicate this.  In your book they use a left pointing arrow in pseudocode to represent this.  You can probably guess that a variable must be on the left side (the sticky note pad we are going to place a value on for later use), and a value of the appropriate type on the right hand side.

 There are other operators that we will talk about as the class progresses.
 
 ##### testing operators
-There are operators that return true or false instead of a numeric value.  Many of these you are already familar with, and most are binary (take two operands):
-  * <     less than
-  * >     greater than

-  * >=    greater than  or equal to
-  * ==    equal to

 You can also combine logic tests together with the operators:
-  * &&    'and' returns true if the items on either side are both true
-  * ||    'or'  returns true if at least one of the items on it's sides is true.
-  
-Finally our first unary operator (meaning it only takes one operand)
-  * !     'not' returns false if the operand following it is ture, and returns true if that operand is false

+## Chapter 3
+
+In this chapter we will start coding and talking about how the various portions of the Java language work.
+
+### How do we convert our flow charts to code?
+
+We have been using three things in our flowcharts:
+
+#### Statements:
+~~~
++---------------------------+
+| Decrease the counter by 1 |
++---------------------------+
+~~~
+~~~
++---------------+
+| Print "Hello" |
++---------------+
+~~~
+If they are simple, these will generally translate into a sngle line of code:
+~~~
+counter = counter -1;
+
+system.out.print("Hello");
+~~~
+If they are complex, then we need to break them down further.  As an example think of the statements in my algorithm where I asked does everyone know about the meeting.
+
+#### Conditionals:
+~~~
+          |
+          |
+          v
+         / \
+        /   \       Yes
+   if our counter \-----------+
+      equals 5    /           |
+        \   /                 v
+         \ /          +---------------+
+          |           | Statement 1   |
+       No |           +---------------+
+          v                   |
++-----------------+           v
+| Statement 3     |   +---------------+
++-----------------+   | Statement 2   |
+          |           +---------------+
+          |                   |
+          +-------------------+
+          |
+          v
+~~~
+
+This translates into the code:
+~~~
+if( counter == 5 )
+{
+   Statement 1
+   Statement 2
+}
+else
+{
+   Statement 3
+}
+~~~
+
+#### loops
+
+Any time we have an edge going back to a previous step, we have a loop.  Thi is an indication that we want to do some steps multiple times.
+
+When we have a loop either it has a conditional in it somewhere that has oneoption tht leaves the loop, or we have a never ending, infinate loop.  We don't want infinate loops, so I'm going to assume that you have such a conditional in the sequence of steps that is repeated, similar to below:
+~~~
+          |
+          v
+  +---------------+
+  | Statement 5   |
+  +---------------+
+          |
++-------->|
+|         |
+|         v
+| +---------------+
+| | Statement 6   |
+| +---------------+
+|         |
+|         v
+|        / \
+|       /   \          Yes      +---------------+
+|   if temp is less \ --------->| Statement 9   |
+|      than 50      /           +---------------+
+|       \   /                           |
+|        \ /                            |
+|         | No                          |
+|         v                             |
+| +---------------+                     |
+| | Statement 7   |                     |
+| +---------------+                     |
+|         |                             |
+|         v                             |
+| +---------------+                     |
++-| Statement 8   |                     |
+  +---------------+                     |
+                                        v
+  ~~~
+
+For this we will wait to start the loop until we get to the conditional, then we will create a loop with the exit condition:
+
+~~~
+Statement 5
+Statement 6
+while( temp >= 50 )
+{
+   Statement 7
+   Statement 8
+   Statement 6
+}
+Statement 9
+~~~
+
+Note that with this condition we had to invert it, as the written test in the flowchart tested to exit the loop, not stay in it.
+
+#### Tests
+How can we test things in conditionals and loops?
+~~~
+When we test something we want the result to be true or false.  We know of some of these and use them regularly:
+* <  less than
+*  >  greater than
+* == is equal to
+* <= less than or equal to
+*  >= greater than or equal to
+~~~
+What if we need something to not be one of these things?  For that we have a not opperator: 
+* !
+
+it can be used with the is equal to opperator to modifyit:
+* != is not equal to
+
+or it can be used with any test:
+* !( 5 > 8 )
+
+note the parenthesis here to indicate what we want the oppisite truth value of (parenthesis still evaluate before the not opperator.)
+
+How could you write the above "temp is less than 50" test other than changing the less than opperator?
+
+
+So you may be asking "What do I do if things get more complicated?"  For example what if you needed to test if a value was less than 10 or greater than 90?
+
+There are multiple ways to do this, but to introduce you to one more tool for tests, I'm going to choose the method that is closest to what was written:
+* (value < 10) || (value > 90)
+
+There are two of these opperators:
+* || logical OR.  If the item on either side is true, then return true, otherwise return false.
+* && logical AND.  Only when the item on both sides is true, return true, otherwise return false.
+
+
+This allows us to build up some wild sentances and translate them into logic:
+If it is not the case that either the sky is blue or the water is red.
+
+becomes:
+if( !( (sky == blue) || (water == red) ) )
+
+### Comments in Java
+~~~
+Use // to indicate that everything after is a comment *works for one row*
+Use /*_____*/ to indicate that everything in between is to be seen as a comment
+          Use comments for assistance too many can be very messy and unneccessary
+~~~
+
+### Initial Set Up
+~~~
+- public class (NAME of File)
+  { 
+          public static void main(String[]args)  (*** These two things are needed to have java run/ This MAIN is a function**)
+          {
+          }
+  }
+~~~
+### Switch Statements
+~~~
+int i
+switch(i%5)
+{
+case 0:
+ -insert commands if condition met for this case -
+case 1
+case 2
+case 3
+case 4
+default:
+print 'i is a multiple of 5"
+}

+1. [Initially create personal GitHub repo from Class repo](#CloneToPersonalGitHubRepo)
+1. [Initially create a copy of personal GitHub repo on a local computer](#CloneToPersonalComputer)
+1. [You have made changes locally that you want to have in your GitHub repo](#PushChangesToPersonalGitHubRepo)
+1. [Move changes from your personal GitHub repo to the class GitHub repo](#PushChangesToClassRepo)
+* [After you crete the repository on your personal space, it is updated](#PullClassChangesToPersonalGitHubReop)
+* [Pulling changes to your local computer that happened after you cloned the repo](#PullUpdatesFromPersonalGitHubRepoToLocalRepo)
+
+
+
+## CloneToPersonalGitHubRepo
+
+You need to have a personal account on GitHub.
+
+* Go to the class repo you would like to copy into your space on GitHub.
+* Click the fork button.
+* Select your name in the window that comes up.
+
+You should now have a copy of the repository that has what was current at the time you created the copy.
+
+
+## CloneToPersonalComputer
+
+You need to have GitBash installed on your computer if you are running windows.  
+If not using windows, then install Git, and use the command line instead of GitBash in these instructions.
+
+* Go to the repo in your personal space on GitHub (your user name will be in the upper left.)
+* Click the green "Clone or Download"button on the right hand side.
+* Copy the link that is shown here (note that clicking on the clipboard icon will copy the text.)
+* In GitBash, navigate to the folder you want te repository to be located in (use the 'cd' command.)
+* Run the command: 'git clone ' and past the link you copied above.  Then hit return.
+
+You should now have a folder with the name of the repository at the location you are at on the computer.
+Inside that should be the files that were in the repository when you cloned it.
+
+
+## PushChangesToPersonalGitHubRepo
+
+* Open GitBash and navigate inside the repository folder.
+* Run the command 'git add -A' to work towards having all changes added.
+* Run the command 'git commit' to make a commit with the changes on these files.
+* Run the command 'git push origin/master' to push the changes in the commit to your personal GitHub repo.
+
+Note: you can run the command 'git status' at any time to get a feel for what has been done/needs to be done.
+* Any files whose name is in red are files that have changes that have not been added yet.
+* Any files whose name is in green have been added, and are waiting on being committed.
+* If a file name does not show up here, then either it current version has been committed, or there has been not change to it.
+
+Also Note, you can always check if this worked properly, as you can log into the GitHub web page, and from there, go to your personal repository for this project.  Check if the changes you made to files are in those files.  If so, then you are good.  If not, ggheck a git status, and verify you did the git push command above.  If neither of those solve your issue, please contact the professor.
+
+
+## PushChangesToClassRepo
+
+* Open up the GitHub website, and go to your personal repository for this project.
+* Click the create pull request button.
+* Make sure your personal repo is on the right, and the class repo is on the left.
+* Click create repo (entering in a description if it wants it, or you want to.)
+* Go through two or three more screens saying yes merge, until it says that either it can't merge, or it merged successfully.
+
+If you get a note that it can't merge, let the professor know.  
+
+
+## PullClassChangesToPersonalGitHubReop
+
+* Go to your personal GitHub copy of the repository.
+* Select new pull request.
+* Make sure the class repository is on the right and your personal is on the left.
+* Select "Create Pull Request", and continue to click the buttons to merge this in.
+
+If you get a merge conflict, and GitHub can not merge, contact the professor for help.
+
+
+## PullUpdatesFromPersonalGitHubRepoToLocalRepo
+
+* In GitBash, go inside the folder for this repo on your local machine.  (usind the command 'cd')
+* Run the command 'git pull origin master'
