10 recommended articles about program memory

This article mainly introduces relevant information that explains in detail the analysis of program memory in Java. Friends in need can refer to this article to briefly explain the memory allocation of the JVM (Java Virtual Machine) when we run a Java program. . First, let’s get to know a few nouns perceptually: 1. Stack. Generally speaking, basic data types allocate space directly on the stack, and local variables (variables defined in the method code segment) also allocate space directly on the stack. , when the method where the local variable is located is executed, the space will be immediately reclaimed by the JVM. There is also a reference data type, that is, what we usually call the reference corresponding to the object that needs to be created using the keyword new is also in the stack space. At this time, the JVM allocates an address space to the object reference in the stack space (equivalent to a house number, through which you can find your home), and allocates a space in the heap space to the referenced object. The address reference points to the object area in the heap space (find the address through the house number); 2. The heap is generally used to store data obtained using the keyword new. Next, we will use a program to intuitively feel the memory situation of the JVM when the program is running, package

2. PHP Kernel - Graphical introduction to memory leaks and new garbage collection mechanism

##Introduction: The garbage collection mechanism is a dynamic storage allocation scheme. It automatically releases allocated memory blocks that are no longer needed by the program. The process of automatically reclaiming memory is called garbage collection. The garbage collection mechanism allows programmers not to worry too much about program memory allocation, so that they can devote more energy to business logic. PHP also implements dynamic management of memory at the language layer, which has been explained in detail in the previous chapters. Dynamic management of memory saves developers from cumbersome memory management. In conjunction with this, PHP also provides a garbage collection mechanism at the language layer, so that programmers do not have to worry too much about the program

3. php garbage collection mechanism

Introduction: Each computer language has its own automatic garbage collection mechanism, so that programmers do not have to worry too much about program memory allocation, php No exception, but in object-oriented programming (OOP) programming, some objects need to be explicitly destroyed to prevent program execution memory overflow. 1. PHP garbage collection mechanism (Garbage Collector, referred to as GC) In PHP, when no variables point to this object, the object becomes garbage. PHP will destroy it in memory; this is PHP's GC garbage disposal mechanism to prevent memory overflow. When a PHP thread ends...

Introduction: SQL Server consultant Brent Ozar recently published an article talking about seven techniques that every SQL Server developer should follow in their daily programming tasks. According to Brent, developers should try to avoid using ORDER BY statements. He also recommended that developers put all query results into application memory and then sort them.
