Hierarchy of Operations

As with all programming language, Java has operator precedence.

In other words, large math equations are not evaluated strictly left to right. Some operators have precendence over others.
To override, use parenthesis.
Java's order of operations is very similar to that in other programming languages.
If two operators have equal precedence, they are evaluated left to right.

The order:

[] . () (method call)
! ~ ++ -- + - () (cast) new	mostly unary operations.
* / %
+ -
>> << >>>	bit shift operations
< <= > >= instanceOf()	comparison
= = !=	more comparison
&	bit ops
^	bit ops
\|	bit ops
&&	and
\|\|	or
?:	ternary
= += -= *= /= %= \|= ^= <<= >>= >>>=	the only one evaluated right to left.
