【JVM源码解析】虚拟机解释执行Java方法（下）

第34篇-解析invokeinterface字节码指令与invokevirtual指令类似，当没有对目标方法进行解析时，需要调用LinkResolver::resolve_invoke()函数进行解析，这个函数会调用其它一些函数完成方法的解析，如下图所示。上图中粉色的部分与解析invokevirtu...

【JVM源码解析】虚拟机解释执行Java方法（上）

第29篇-调用Java主类的main()方法前面已经写了许多篇介绍字节码指令对应的汇编代码执行逻辑，还有一些字节码指令对应的汇编代码逻辑没有介绍，这些指令包括方法调用指令、同步指令、异常抛出指令，这些指令的汇编代码实现逻辑比较复杂，所以后面在介绍到方法调用、同步和异常处理的知识点时，会通过大篇幅的文...

JVM | 第2部分：虚拟机执行子系统《深入理解 Java 虚拟机》

前言参考资料：《深入理解 Java 虚拟机 - JVM 高级特性与最佳实践》第1部分主题为自动内存管理，以此延伸出 Java 内存区域与内存溢出、垃圾收集器与内存分配策略、参数配置与性能调优等相关内容；第2部分主题为虚拟机执行子系统，以此延伸出 class 类文件结构、虚拟机类加载机制、虚拟机字节码...

Java-jVM-虚拟机判定两个 Java 类是相同

类加载器基本概念顾名思义，类加载器（class loader）用来加载 Java 类到 Java 虚拟机中。一般来说，Java 虚拟机使用 Java 类的方式如下：Java 源程序（.java 文件）在经过 Java 编译器编译之后就被转换成 Java 字节代码（.class 文件）。类加载器负责...
