+# Syntax Refrence
+Here you'll find a quick refrence to some basic java syntax.
+
+### Built-In Data Types
+* `String` - Stores text, such as "Hello". String values are surrounded by double quotes.
+* `int` - stores integers (whole numbers), without decimals, such as 123 or -123.
+* `double` - stores floating point numbers, with decimals, like 19.99 or -3.14159265. Double values end with `d`. (for people with experience, we will not be using `float` in our code).
+* `char` - stores single characters, such as 'a' or 'B'. Char values are surrounded by single quotes
+* `boolean` - stores values with two states: `true` or `false`
+
+### Variables
+```java
+type variableName = value;
+```
+Assignment:
+```java
+variableName = newValue;
+```
+Example:
+```java
+String greeting = "Hello World";
+double treeHeight = 12.2d; // meters
+int funnyNumber = 67;
+funnyNumber = 41;          // funnyNumber is now 41
+```
+
+### Logic
+Operators
+ - `<`, `>`: Less than, Greater than
+ - `<=`, `>=`: Less than or equal to, Greater than or equal to
+ - `==`: Equivalent to
+ - `!=`: Not equivalent to
+ - `!`: Not (inverts any boolean after it, so true->false and vice-versa)
+ - `&&`: And (True: `(1 == 1) && (2 == 2)`, checks if 1 is equal to 1 **and** 2 is equal to 2)
+ - `||`: Or (True: `(1 == 1) || (2 != 2)`, checks if 1 is equal to 1 **or** 2 is equal to 2)
+
+If Statements: 
+```java
+if (condition1) {
+    // Runs if condition1 is true
+} else if (condition2) {
+    // Runs if condition1 is false but the 2nd condition is true
+} else {
+    // Run if condition1 is false and condition2 is false
+}
+```
+
+### Classes
+Classes need to be named according to the file name and must use a capital letter at the start
+```java
+class Car {
+    private double speed = 0;
+
+    public boolean isMoving() {
+        return speed == 0;
+    }
+
+    public void accelerate() {
+        speed += 1;
+    }
+    
+    public void decelerate() {
+        speed -= 1;
+    }
+}
+```
+- `public`: Accessable from instances of class and inside of its methods
+- `private`: Only accessable from inside the class's methods
