git enforced \n line endings
4-spaces instead of tabs for indentation
Spaces after control statements before beginning parenthesis or brace
```
if (
```
```
for (
```
```
while (
```
```
do {
```
```
try {
```
```
public class SomeClass {
```
Spaces after closing parenthesis in a control statement
No newline after closing parenthesis and space in a control statement:
```
if () {
```
```
for () {
```
```
while () {
```
```
catch () {
```
```
switch () {
```
Newlines before an else, else if, catch, and finally statement
```
}
```

else {

```
}
```

else if () {

```
}
```

catch () {

```
}
```

finally () {

Space after ; in for statement, not before
```
for (int i = 0; i < 10; i++) {
```
Spaces around operators
```
a + b
```
```
a == b
```
```
for (Type blah : blahs) {
```
```
"String " + "concatenation"
```
Spaces around { and } on one-line declarations

public boolean aMethod() { return something; }

Fewer extraneous parentheses, except when they increase readability
```
if (a == b || b == c)
```
Indent on case in switch case statements
```
switch () {
         case 1:
```
Mandatory comment for when a case falls through, and when not stacking

switch () {
         case 1:
             // Fallthrough

         case 2:

switch () {
         case 1:
         case 2:
         case 3:
         case 4:
         case 5:
             // Fallthrough

         case 6:

Empty line between cases after break, return, or fallthrough

switch () {
         case 1:
             break;

         case 2:

Prefer early returns over method indentation. Example:

if (!precondition) {
         // Possibly cleanup
         return;
     }

     // Continue with task

Java standard class and method naming, with exception to McMMO in a class name
```
thisIsAMethod()
```
```
ThisIsAClass
```
Exception:

McMMOCustomClass

No space before opening parenthesis for methods, or constructors
```
public void thisIsAMethod() {
```
```
public ThisIsAClass() {
```
Spaces after comma in method calls and constructors, not before

something.methodCall(variable, otherVariable);

Accessing of variables with this. only when necessary to resolve scope
Class variables always defined at the top, before the constructor
No empty line between class declaration and beginning of variable declaration
Always a empty line at the end of a method or constructor definition
Constructors come before methods, and are typically ordered from the ones with the least arguments to the most
Methods should be ordered in this manner:
override public
public
static public
abstract public
override protected
protected
static protected
abstract protected
private
static private
No one-line if statements, they should all have brackets
