--reference Java Heap Memory vs Stack Memory Difference 在数据结构中,堆和栈可以说是两种最基础的数据结构,而Java中的栈内存空间和堆内存空间有什么异同,以及和数据结构中的堆栈有何关系? 一.Java 堆存储空间 堆内存(堆存储空间)会在Java运行时分配给对象(Object)或者JRE的类.只要我们创建了一个对象,那么在堆中肯定会分配一块存储空间给这个对象.而我们熟知的Java垃圾回收就是在堆存储空间上进行的,用以释放那些没有任何引用指向…

JVM管理的内存可以总体划分为两部分:Heap Memory和Native Memory.前者供Java应用程序使用的:后者也称为C-Heap,是供JVM自身进程使用的.Native Memory没有相应的参数来控制大小,其大小依赖于操作系统进程的最大值,以及生成的Java字节码大小.创建的线程数量.维持java对象的状态信息大小(用于GC)以及一些第三方的包,比如JDBC驱动使用的native内存. Native Memory里存些什么?(1)管理java heap的状态数据(用于GC);(2…

JVM管理的内存可以总体划分为两部分:Heap Memory和Native Memory.前者我们比较熟悉,是供Java应用程序使用的:后者也称为C-Heap,是供JVM自身进程使用的.Heap Memory及其内部各组成的大小可以通过JVM的一系列命令行参数来控制,在此不赘述.Native Memory没有相应的参数来控制大小,其大小依赖于操作系统进程的最大值(对于32位系统就是3~4G,各种系统的实现并不一样),以及生成的Java字节码大小.创建的线程数量.维持java对象的状态信息大小(用…
