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

postfix operators	[] . (params) expr++ expr--
unary operators	++expr --expr +expr -expr ~ !
creation or cast	new (type)expr
multiplicative	* / %
additive	+ -
shift	<< >> >>>
relational	< > >= <= instanceof
equality	== !=
AND	&
exclusive OR	^
inclusive OR	|
conditional AND	&&
conditional OR	||
conditional	?:
assignment	= += -= *= /= %= >>= <<= >>>= &= ^= |=

?

<<?	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

Today, It's my first time to log some thoughts and ideas on Internet although i have this mind long long ago. Because many times i can get much experiences from others, i also want to share some good things with many people who have same ambition or worked for same fields. I consider that it have two advantages for me, one is that it can help me accumulate more knowledges. After all when you write some outside or share something, they must be tested or verified. At the process of verifying, i will get more amazings and pleasure. The other is that it can improve my english-writing. Although i write many docs in english at comapny, i can try more words to express my feeling. It's more interesting than done in company. OK, writing here today and complete setting enviroment and write some little doc. Hope anyone visited my blog can make friends with me and leave something to me for technology or English.
