堆战栈是JVM外两个蹙迫的内存地区，它们的首要离别如高：

一、用途：堆用于存储工具伪例战数组，是渣滓发受接管的首要地区；栈用于存储部份变质、操作数栈战兑现流。

两、线程分享性：堆是被统共线程分享的内存地区，而栈是线程独占的。

三、内存分配：堆的内存分配是静态的，折用于静态工具的存储；栈的内存分配是攀附的，折用于暂时变质的存储。

四、内存发受接管：堆的内存发受接管由渣滓发受接管器弄定，栈的内存分配战发受接管是踊跃的。

The heap and stack in the JVM are two important memory areas with distinct differences. Here are the main distinctions between them:

Purpose: The heap is used for storing object instances and arrays， and is the primary area for garbage collection. The stack， on the other hand，凯发k8 is used for storing local variables， operand stacks， and control flow.Thread Sharing: The heap is a memory area shared by all threadsk8凯发app下载， while the stack is thread-private.Memory Allocation: Heap memory allocation is dynamic， suitable for storing dynamic objects. Stack memory allocation is contiguous， suitable for storing temporary variables.Memory Reclamation: Heap memory reclamation is handled by the garbage collector， while stack memory allocation and reclamation are automatic.
