Java memory allocation and GC, Java memory allocation GC Java memory allocation and recovery mechanisms are summarized as follows: generational allocation and generational collection. Objects are divided into Young Generation, Old Generation, and Permanent Generation Based on the survival time ). The memory space occup

Analysis of memory managementThe following behavior increases the memory footprint of an app:1, create an OC object;2, define a variable;3, call a function or method.If the app takes up too much memory, the system may force the app to close, causing a flashback and impacting the user experience. How can I recycle objects that are no longer in use? This article fo

Often encounter someone want to replace memory do not know what kind of memory to buy, also often meet people ask upgrade memory to buy what kind of memory is compatible, here to share a bit, incidentally popular science.

Memory overflowOne, the popular understanding is that the memory is not enough, usually when running large software or games, software or games need more memory than the memory installed in your host size, called memory overflow. At this point the software or game will not r

I. Terms of virtual memory Virtual Memory In the storage allocation mechanism, although the standby address is a part of the primary memory, it can also be addressable. The address used by the program to reference the memory is different from the physical address used by the

associate "result" with a general register. First, read the value of the operand into the Register, and then use the corresponding register in the instruction, instead of the result itself, of course, after executing the command, you need to store the value in the Register into the variable "result". On the surface, it seems that the command directly performs operations on "result". In fact, GCC implements implicit processing, in this way, we can write less commands. "R" in front of "input" ind

Dynamic Memory Management --- new delete, dynamic memory --- newDynamic Memory ManagementA Dynamic Object (heap object) is an object created by using the new operator in the dynamic memory during running of a program.Because the user created it by using the new operator, the user is also required to use the delete ope

Memory Overflow (OOM): a situation in which running memory is larger than available memory. For example, the application of an integer space, the result is stored only a long to store the data memory leak (memory leak): The programmer forgot to release the

In interviews, the interviewer often asks, "Do you know what a memory overflow is?" What is a memory leak? How to avoid it? "With this article, you can answer it."A memory overflow (OOM) means that the program does not have enough memory space for its use when requesting memory
