I have a solution: the previous post may not be quite understandable, and I did write a few comments, and the steps are not very detailed. I hope you can correct them again. 1: Controls (cracked version, only.

I have a solution: the previous post may not be quite understandable, and I did write a few comments, and th
the heap is completely different: it is more like a conveyor belt. Every time a new object is allocated, it moves one cell forward.
This means that the object storage space is allocated very quickly. Java's "heap pointer" is simply moved to an unallocated area, which is more efficient than the space allocated by C ++ on the stack. Of course, there are a small amount of additional expenses in the bookkeeping work in the actual process, but it is not a
"dynamic", and it will change the model. When an object is created, the use of the garbage collector has a significant impact on the speed of object creation. On the surface, this seems a bit strange-the release of a bucket may affect the allocation of a bucket, but it is one of the important methods adopted by JVM, this means that allocating storage space for heap objects in Java is almost as fast as creating a bucket in the stack in C ++.
You can think of a C ++ heap (and a slower Java heap)
