The Java class template belongs to static things that are placed in the method area;The Java object is placed in the stack memory;Java instances are placed in heap memory (new out-of-object data);For example:Note: There is no object in the static method, naturally there is no this,super (memory perspective, is static something generated in the class template, whi

areas with the main thread; 4. When the child thread runs, it executes a separate thread function, which is set when the thread is created; Finally, let's talk about the Pthread_create function, in Linux the function is to create a thread through clone, the child thread can have its own stack area, and the main thread shared code area, the data area and the heap area to benefit from the Clone function, the following is the function of the Clone function prototype, Please refer to: int

Written by the DHT protocol search procedures, these days optimized to find that the speed is indeed much faster. But there was a new problem, the memory soared, and I opened 10 crawlers to occupy the memory 800m. At first I thought it was too many nodes, I found a few minor problems to modify, and find it useless. Then I went online to find the Python memory ana
