JVM Memory Model Fundamentals

Hello everyone, I am Yi An!

We know that to run a Java application, we must first install the JDK or JRE package. This is because Java applications become bytecode after compilation, and then run in the JVM through bytecode, which is the core component of JRE.

The JVM not only undertakes the analysis (JIT compiler) and execution (Runtime) of Java bytecode, but also has a built-in automatic memory allocation management mechanism. This mechanism can greatly reduce the risk of memory leakage and overflow that may arise from manual allocation and recycling mechanisms, allowing Java developers to focus more on the business itself without having to worry about memory allocation and recycling for each object. But understanding JVM memory allocation and tuning is the true entry into the Java language. Today, let’s first take a look at the JVM memory model.

JVM Memory Model Design

Today we mainly delved into the most basic memory model design, understanding the roles and implementation principles of its various partitions. The content is basic, and we believe you will soon master it.
