当栈空间满了,Java运行时会抛出 java.lang.StackOverFlowError ,然而堆空间满了,抛出的是 java.lang.OutOfMemoryError: Java Heap Space 错误 栈空间相比较于堆空间是非常小的,又因为栈中使用最简单的先进后出(LIFO)原则,它是远远快于堆的。
Memory density on the stack tends to be higher than on the heap because of the reference type overhead (discussed later in this chapter). Higher memory density often leads to better performance, e.g., because more objects fit in the CPU cache. Thread stacks tend to be fairly small – th...

When stack memory is full, Java runtime throwsjava.lang.StackOverFlowErrorwhereas if heap memory is full, it throwsjava.lang.OutOfMemoryError: Java Heap Spaceerror. Stack memory size is very less when compared to Heap memory. Because of simplicity in memory allocation (LIFO), stack memory is ...

Heap memory is used by all the parts of the application whereas stack memory is used only by one thread of execution. Whenever an object is created, it’s always stored in the Heap space and stack memory contains the reference to it. Stack memory only contains local primitive variables and...
Java - heap (JVM Memory) All objects are stored on the heap. Stack is used for local primitive variables such as ints and doubles. But all objects such as strings, customers or integer objects will be store on the heap. For the objects on the heap there'll be a pointer to the ...

虚拟机栈过多,无法申请到足够内存会引发 java.lang.OutOfMemoryError 异常 本地方法栈 本地方法栈(Native Method Stack)与虚拟机栈相似,主要作用于标注了 native 的方法。 二者的区别在于:虚拟机栈为 Java 方法服务;本地方法栈为 Native 方法服务。本地方法并不是用 Java 实现的,而是由 C 语言实现的。
Java堆(Heap):用于存储对象实例。堆是Java内存管理中最大的一块区域,也是垃圾回收的主要工作区域。 方法区(Method Area):用于存储类信息、常量、静态变量、方法字节码等。在不同的JVM实现中,方法区也被称为“永久代”或“元空间”。 Java栈(Java Stack):用于存储局部变量、方法参数、方法返回值和操作数栈等。每...
