        for String concatenation)
-       Subtraction operator
*       Multiplication operator
/       Division operator
%       Remainder operator

Unary Operators

+       Unary plus operator; indicates
        positive value (numbers are 
        positive without this, however)
-       Unary minus operator; negates

!=      Not equal to
>       Greater than

?:      Ternary (shorthand for 
        if-then-else statement)

Type Comparison Operator

instanceof      Compares an object to 
                a specified type 

Bitwise and Bit Shift Operators

<<      Signed left shift
>>      Signed right shift
>>>     Unsigned right shift
&       Bitwise AND
