Java Virtual Machine Definition Java virtual machines are called "virtual" because they are just abstract computers defined by a specification. What is a Java

This blog post focuses on the components of the JVM (Java Virtual machine) and how they work within them. It is important to note that although most of the times we use the JVM provided by Sun (now acquired by Oracle), the JVM itself is a specification, so there are many implementations, in addition to hotspots, such as Oracle's JRockit, IBM's J9 are also very we

the principle and implementation of Java Virtual machine class loading (RPM)First, IntroductionThe class load of a Java Virtual machine (JVM) is the process of loading the bytecode contained in the class file into the JVM and maki

JIT compiler , English writing just-in-time Compiler, Chinese means instant compilerThe reason the class field does not need to be initialized:After the memory allocation is complete, the virtual machine needs to initialize the allocated memory space to a value of 0 (excluding the object header), and if Tlab is used, the work process can also be advanced to Tlab allocation. This step ensures that an instanc

recycling algorithm for recycling, so it seems that classification is so troublesome, in fact, it is very good.Referring to the memory structure of a virtual machine, the first thing you might think about is the stack. Objects are allocated on the heap, and the stack is used to assign the reference to the object and some basic data type-related values. However, the memory structure of the

Loading of classes in Java virtual machines(approximate structure of the JVM)From sending class files to in-memory classes, in order of precedence, there are three major steps that need to be loaded, linked, and initialized.The types of Java languages can be divided into two main categories: the base type (primitive type) and the reference type (references type)B
