algorithm for the new generation of garbage collection. Advantages: Garbage collection objects are more than a few objects that need to be copied, less hate, better performance; there is no memory fragmentation. Disadvantage: The system will be half a passbook.

business primary key needs to be redundant in important tables, and the best way to handle this is to use the business primary key directly. such as social Security number, Passbook number, card number and so on. So usually the banking system requires the use of a business primary key, which is not due to performance considerations but for security reasons.The primary reason for using a composite primary key is related to using a business primary key

This week, the USPTO unveiled a patent application called "How to adjust NFC in the mobile payment process." The Apple Pay feature and the NFC hardware architecture and working modes are described in detail in the patent file.First, Apple introduces its contactless payment system in patent documents. Relying on NFC technology, such as components in the IPhone6 and 6 Plus, the user device can monitor the magnetic field formed around the merchant POS terminal. After the phone and POS terminals are
the existing system to the logic primary key. At the moment, I have not thought of any other scenarios such as conversion.
Another reason for using the business primary key is that the security of the banking system is more important than the performance. In this case, we will consider using the business primary key, which can be both a primary key and redundant data, avoid Association loss caused by the use of logical primary keys. If the association between the primary table and the sub-ta

Helios is an open-source framework that provides effective background services for IOS. It integrates payment and Passbook for data synchronization and message sending in-app. In just a few minutes, developers can get the response from the client/server program and run it without any integration functions.
Helios is a cluster of mobile background components-mixed and matched to meet your specific needs
or block of code until the lock is freed. A release lock is a lock thread that exits the synchronized synchronization method or code block.For synchronization, there are generally two things to do in Java code:① identifies the resource that is competing for access as private.② synchronizes the code that accesses the resource, which is automatically freed when the Synchronized keyword executes or an exception occurs.Sample requirements:① a bank card account has 500 yuan in cash. One person takes

If multiple threads access shared resources, the shared resources may be insecure when one thread does not process the business and another thread enters.
Daily example: A and B have the same bank account, A uses the passbook to get the money at the counter, and B uses the cash machine to get the money. There are two key steps to withdraw money:
(1) Determine
stack, and the heap is a program run dynamically allocated memory space, you can dynamically allocate the size of memory according to the program's running situation. Therefore, the value type always consumes a predefined number of bytes in memory. A variable of reference type allocates a memory space in the stack, which contains a reference to another memory location, which is an address in the managed heap, where the actual value of the variable is stored.
That is, the value type is equivalen
++ returns the Bbody value 9.0. In essence, B has already been + 1, that is, B = 10.0.
A ++ * B ++ => 2.0*9.0 => 18.0
And then call:
A ++ returns the value of a itself, which is 3.0. Essentially, a has already been + 1, that is, a = 4.0.
B ++ returns the Bbody value 10.0. In essence, B has already been + 1, that is, B = 11.0.
A ++ * B ++ => 3.0*10.0 => 30.0
What is the difference between the value type and the reference type? How to judge them? First, it helps you intuitively understand that th
CustomA reference type indicates that the data you are manipulating is the same, meaning that when you pass a parameter to another method, you change the value of the variable in another method,Then calling this method is the value of the passed variable will also change. A value type means that a current variable is copied to the method,When you change the value of this variable in this method, the value of the initial life variable will not change. Popular parlance: The value type is cash, mus
