Thread-safe HttpClient Fortunately, android provides a thread-safe HttpClient that can be created through ClientConnectionManager.

First review the simple interest design pattern: The simple interest design pattern is a way for a class to create only one instance of an object for outside use. Simple interest design patterns are divided into lazy and a hungry man: A Hungry man is thread-safe:1 //a hungry man type simple interest design mode:2 classsingle{3 Private Static FinalSingle =NewSingle ();4 PrivateSingle () {}5 Public StaticSingle getinstance () {6

Each string of characters can be encoded into numbers to store information, but different encoding methods get the same storage space! And when the storage space

The Java class library includes a number of useful "base module" classes. In general, we should prefer to reuse these existing classes instead of creating new ones. : Reuse can reduce development effort, develop risk (because existing classes are already tested), and maintenance costs. Sometimes, a thread-safe class can support all the operations we need, but many other times, the existing class can only support most of the operations, and it is neces

There are about two ways to implement a single example: lazy and a hungry man. lazy: Hence the name of righteousness, not to the last resort to instantiate the class, that is, the first time to use the class instance will be instantiated, so the top of the classic method is classified as lazy implementation; a hungry man: you must be hungry. So it is instantiated when the Singleton class is defined. Features and selection: Because of the thread synchronization, it is possible to achieve be

. But I did not expect the problem of black screen still appearing after reboot. Because the computer is integrated graphics card, the display of the interface has DVI and the traditional VGA interface two, in order to obtain the best compatibility, and the original DVI interface into VGA connection monitor, but the problem remains. is the motherboard's consolidated graphics card unable to support Windows7? Helpless under the sudden thought, perhaps can enter into

Enter Safe mode is generally in the boot when press F8 key, but rookie will often miss the timing of the F8 button and lead to the computer directly started, which has to restart the computer to press F8 again. Isn't it troublesome to be so repetitive? In fact, we can add safe mode to the system boot menu to facilitate our operation. Add "Safe Mode" to the Start

Reentrant: When a program executes to a function foo (), receives the signal, then pauses the currently executing function, goes to the

Preface: When multiple threads access a thread-safe resource, such as the UI, there must be some kind of mechanism to ensure that these threads operate aling. If resources requiring thread-safe are simultaneously accessed by other threads without any measures, the following similar invalidoperationexception will be thrown.
