, which you can use to prepare for the interview. 1) What is a thread?A thread is the smallest unit that the operating system can perform operations on, which is included in the process and is the actual operating unit of the process. Programmers can use it for multiprocessor programming, and you can speed up operations-intensive tasks using multithreading. For example, if a thread takes 100 milliseconds to complete a task, it takes 10 milliseconds to complete the task with 10 threads. Java pro

Surface was released, and I quickly purchased one. I want to study it and see if I can make some applications on it. I tried it for a few days and summarized some of my feelings.Poor experience:1. There are few applications in the Win8 RT mode PC, and none of the most common software input methods are available.2. There are few applications under a tablet. Although it is growing every day, there are still few software commonly used or evaluated on oth

HttpGet request. Post method if data is transferred? Simulates a form submission, encapsulates the data into a list collection, and then puts the collection data into the constructed form entity, placing the form entity request into the HttpPost object. Throws an interface outward, the execution procedure is: 1, creates the HttpClient object 2, constructs the Request object post, the GET Request 3, if has the parameter, constructs the request paramet

of cycles, with no additional overhead. There is no increase in space.The memory occupied by local variables is one-time, that is, the space complexity of O (1), and for recursion (regardless of the case of tail recursion optimization), each function call must be stacked, then the space complexity is O (n), and the recursive number is linear.(3) The recursive program to use the loop implementation, it is generally necessary to maintain a stack itself

? (call run () and call Start () the difference) A: 1), new State (new): A newly created thread object. 2), Ready State (Runnable): After the thread object is created, other threads call the object'sStart () method. The state of the thread is located in a pool of running threads that becomes operational and waits for the CPU to be used.3), running State (Running): The ready state of the thread acquires the CPU and executes the run () method.

After the buffer of the surface is ready, you can write bitmap data to the buffer,The buffer of the surface is the same as the ordinary image data. It is also a scanned line data organized in a certain format. The following example assumes that the source and target formats are both 32-bit and the size does not exceed the standard. Uint8_t * sbits;Sbits = (uint8_t *) Bitmap-> getpixels (); Int sstride;Sstri

The description is very simple. Given the coordinates of some vertices, return true if they are in the same line. The topic description is very simple. Given the coordinates of some vertices, return TrueIf they are in the same line. For example[7, 4], Which indicates a point. onLine([[1,2], [7, 4], [22, 9]]); // returns trueonLine([[1,2], [-3, -

What are some of the methods that must be performed when jumping between two activity.In general, for example, there are two activity, called a A, a, when the B component is activated in a, a calls the OnPause () method, then B calls OnCreate (), OnStart (), Onresume (), This time B overrides the form, and a calls the OnStop () method. If B is a transparent, or a dialog box style, the OnStop () method is not called4. The li
