堆内存是区别于栈区、全局数据区和代码区的另一个内存区域。堆允许程序在运行时动态地申请某个大小的内存空间。
-Xms128m 表示JVM Heap(堆内存)最小尺寸128MB,初始分配 -Xmx512m 表示JVM Heap(堆内存)最大允许的尺寸256MB,按需分配。

例如,健康指示器可以用来跟踪数据库堆内存的消耗量。
For instance, a health indicator is used to track the consumption of the database heap memory.
如果您的应用程序出现了内存泄漏,堆内存使用量将随时间稳步增长。
If a memory leak is present in your application, the heap memory usage steadily increases over time.
因此,随着可用堆内存的减少而导致更频繁的垃圾回收,性能可能会降低。
As a result, performance can degrade as the decreased available heap memory leads to more frequent garbage collection.
It turns out that slightly before the stack, slightly before this conceptual chunk of memory, there's other things called environment variables that we may see over time but elsewhere in memory are other things.
结果是稍微在堆之前,稍微在这个内存块概念之前,另外还一个东西叫做环境变量,我们之后可能看到,内存中的其他地方,是其他的东西。
That is the address in memory in the heap of the first byte that the user typed in.
那是用户输入的字符串第一个字节,内存中堆的地址。
So the heap is a chunk of memory in a computer's RAM that's conceptually allocated to what's called dynamic memory allocation.
堆是在计算机RAM中的一块内存,它可以进行,动态内存分配。
