How to check jvm memory usageMethods to check jvm memory usage: 1. Use command line tools; 2. Use JMX; 3. Use Java code; 4. Use VisualVM; 5. Use MAT; 6. Use Java Mission Control; 7. Customize monitoring and analysis tool. Detailed introduction: 1. Use the command line tool, you can use the jstat command line tool to view the memory usage of the JVM; 2. Use JMX, which is a standard API of the Java platform, used to manage and monitor Java applications, etc.
What is the jvm memory modelThe jvm memory model is a model that describes how Java programs are allocated and managed in JVM memory at runtime. It defines the storage and life cycle of various variables in the program, and how the JVM interacts with the computer's physical memory. Its main components include heap memory, stack memory, method area, program counter and local method stack. These components and features work together to enable Java programs to run efficiently in limited memory space, while also providing programmers with a wealth of tools and means to optimize program performance and reduce memory consumption.
What is the jvm memory structure and functionJVM memory structure: 1. Program counter; 2. Java virtual machine stack; 3. Local method stack; 4. Heap; 5. Method area. Its functions: 1. Program counter, used to record the address of the next instruction to be executed, which is a private memory area of the thread; 2. Java virtual machine stack, which saves the local variables of the method, part of the results, and the method call and return information. Each thread has its own virtual machine stack. Each method call creates a stack frame to store relevant execution information. The Java virtual machine stack is also private to the thread; 3. Local method stack, etc.
How to implement JVM memory model and GC tuning of Java underlying technologyHow to implement the JVM memory model and GC tuning of Java's underlying technology Introduction: As a widely used programming language, Java's underlying technology is crucial to developers. Among them, the JVM's memory model and GC tuning are very critical parts. This article will introduce the relevant knowledge of JVM memory model and GC tuning in detail, with specific code examples. 1. JVM memory model The JVM memory model is the memory layout used by JavaVirtualMachine (JVM) at runtime.
Case explanation JVM memory space (recommended collection)Today, let’s talk with you about the topic of JVM memory space. This is also a question that is often asked in interviews at first-tier Internet companies. It is recommended that friends collect it and read it often, focusing on understanding. Okay, no more talk, let’s get to the main topic today.
