Control the startup sequence of two threads. In the interview, I encountered the following question: How can I control thread B to start after thread A starts for 3 seconds or after thread A finishes running? The question shows that thread B's start time must meet two conditions: 1. 3 seconds after thread A starts 2. After thread A finishes running That is to say, as long as one of the above two conditions is met, thread B will start. Use CountDownLatch to control the call sequence. The Code is

understand them very quickly.2. Dimension (Dimension)A dimension corresponds to an argument in a function, or an axis in a function image, which is an n-dimensional vector in linear algebra.(This is also the origin of the name of the dimension). In netCDF, a dimension has a name and range (or length,is a mathematically defined domain, which can be a discrete set of points or a continuous interval. In netCDF, the length of the dimension is basically limited,There can be at most one dimension wit

Dealing with this deadlock problem, spent several days, I believe that the classmate met, same headache, but there is a good helper class words (fortunately. NET API is strong enough), there is no such a headache attention The solution for this article is only for use with lock (obj) or: Monitor.Enter (obj); .... The way Monitor.Exit (obj)A deadlock similar to purple If you are using: Autoresetevent.set/rest, Monitor.wait/pulse, Mutex way, please find another method. Auxiliary class -----------

Recently many new advanced DVD machines have mostly used progressive scan technology, such as Panasonic DVD-H1000, Pioneer DV-AX10, s10A and so on. This kind of progressive scan is different from the interlace scan used by DVD machines. What are the characteristics and benefits of this technology? I will introduce this new technology to you now. If you want to scan prog
