+### Modifiers
+
+```java
+private
+public
+```
+
+- These are two examples of modifiers in java. Will cover more in chapter 3
+
+### Mutator Vs Accessor Methods
+
+```java
+public void changeColour( int newColour ) 
+{
+	colour = newColour;
+	draw();
+}
+```
+
+- An example of a **mutator** method. Since the method **mutates** an integer, and does not return a value.
+
+```java
+public int getPrice()
+{
+	return price;
+}
+```
+
+- This would be an example of an **accessor** method. Since this accesses a value and outputs to a location.
+
+### Formal Vs Actual Parameter
+
+```java
+public void changeSize( int newDiameter )
+```
+
+- newDiameter is the **formal** parameter
+- The value of newDiameter is the **actual** parameter
+
+### Good Practices
+
+- Vertically align braces, since it allows for better error checking
+
+### Extra Stuff
+
+- Homework Wednesday
+- Name everything exactly, marking is automated
