the thread pool is closed or the task throws a runtimeexception.This shows that the basic principle of the thread pool is actually very simple, nothing more than pre-boot some threads, thread into the dead loop state, each time from the task queue to get a task to execute, until the thread pool is closed. If a thread terminates due to an exception executing a task, re-create a new thread. So repeated.In fact, the thread pool principle looks simple, but the complex is a variety of strategies, su

Describe There is an apple tree in the Tautau's yard, and 10 apples will be produced in every fall tree. When Apple matures, Tata will run to pick apples. Tata had a 30-centimetre-high bench, and when she couldn't pick it up with her hand, she would step on the bench and try again. Now that you know the height of 10 apples to the ground and the maximum height you can reach when the Tata handle is stretched, help Tata calculate the number of apples she can pick. If she tou

To put it simply, in the vertical list, the content block is one by one. When the content is large and not fixed, it depends

mechanism between threads. For different processes , they have a separate data space, which is not only time-consuming but also inconvenient to carry out data transfer only through interprocess communication . Threads otherwise, because data space is shared between threads in the same process , the data of one thread can be used directly by other threads, which is not only fast, but also convenient. In addition to the advantages described above, multi-threaded process as a multi-tasking, concur

Questions and codesRead the textbook example 10.1. This example implements a complex number class, but in the ointment, the real and imaginary parts of the plural class are fixed only as double types. The complex can be designed by the technical means of the template class to make the type of the real and imaginary parts the actual type specified when the object is defined.(1) A class member function is required to be defined outside the class.(2) On
