Today for the first time to interview, there are many questions can not answer, please the Great God Advice
The first time I went to the interview, I found a lot different from the textbook.
3. A brief introduction to hibernate?
8. Can you familiarize yourself with the configuration of the James server? And how much does the docs command remember? Project
11. How did Java development turn into PHP development?
What is the difference between 14.InnoDB and MyISAM?
15. Use the EL expression to write the path to the URL.
These questions, some even the name do not know, feel a very wide test, ask the great God advice
------to solve the idea----------------------
What's the difference between InnoDB and MyISAM?
InnoDB support transaction, MYISAM not supported
InnoDB Slow, MyIsAm fast
InnoDB cannot be copied directly, MyIsAm can be copied directly
------to solve the idea----------------------
InnoDB supports row-level locks and has advantages over MyISAM in high-concurrency write situations
InnoDB count () is traversed every time
It doesn't look like a PHP interview.
------to solve the idea----------------------

echo 12 ^ 9; Output is 5
Echo 12^10;//6
Echo 12^12;//0
First turn 2 binary, in the operation of XOR.
XOR operation, Same bit = 0-bit different =1
For example, the binary of 12 is
1100
The binary of 9 is
101
Then 12 ^ 9 equals, Bitwise XOR or
1100
0101
Concluded
1001
Decimal =9 of 1001
