Class (2)-Destructors and garbage collection

Once a class is defined, we can new any number of objects. At this point, the memory allocation on the managed heap and stack is generated, and the heap will open up a new space to store the class object, and the stack simply stores the reference.

Analysis of JavaScript garbage collection mechanism

When companies often hear discussions about memory leaks, everyone is amazed. Recently, my focus has been on Web development, I read "JavaScript advanced programming" (the title is very good, but the actual author wrote it very well, from a simple

Garbage collection algorithm (5) Generational recycling

Generational garbage collection, based on the "most objects will become garbage immediately after they are generated."This empirical fact is the starting point of design. This paper discusses the other garbage collection algorithms based on the fact

A talk about the impact of. NET destructors on garbage collection

Here, the destructor is not accurate, it should be called the Finalize function, the Finalize function form and C + + destructor is very similar, are (~classname) Form, but functionally completely different. After the destructor is compiled into the

A simple understanding of the Java garbage collection mechanism and the role of the Finalize method _java

When the garbage collector wants to reclaim objects, you first call the Finalize method of the class (you can write the program to validate the conclusion), and the normal Java-written class does not need to overwrite this method, because object has
