1. Any primitive
type is overflow, it will became minus number and absolute value will be
one larger. For example, Byte.MAX_VALUE is 127, then it will be equal to -128,
same to other types
Meanwhile, if it is underflow, it will became positive and be equal to
Max_Value
2. Operation precedence and order

|
<<
|
Shift bits left, filling with zero bits on the right-hand side
|
|
>>
|
Shift bits right, filling with the highest (sign) bit on the left-hand
side
|
|
>>>
|
Shift bits right, filling with zero bits on the left-hand side
