Java Operators
| Operators | Function | Associativity | Type |
| () | Anything in () happens first like in math | left to right | parentheses |
| ++ -- | 1 is added or subtracted to the variable after the opperation is complete | right to left | unary postfix |
| ++ -- + - (type) | ++ -- as above except it happens before operation |
right to left | unary |
| * / % | * multiply |
left to right | multiplicative |
| + - | + addition |
left to right | additive |
| < <= > >= | < less than <= less than or equal to > greater than >= greater than or equal to |
left to right | relational |
| = = != | = = equality != not equality ! not |
left to right | equality |
| ?: | right to left | conditional | |
| = += -= *= /= %= | = assigned to equal | right to left | assignment |
