Java 方法有两种返回方式，一种是 return 语句正常返回，一种是抛出异常。不管哪种返回方式，都会导致栈帧被弹出。也就是说， **栈帧随着方法调用而创建，随着方法结束而销毁。无论方法正常完成还是异常完成都算作方法结束。**

除了 `StackOverFlowError` 错误之外，栈还可能会出现`OutOfMemoryError`错误，这是因为如果栈的内存大小可以动态扩展， 如果虚拟机在动态扩展栈时无法申请到足够的内存空间，则抛出`OutOfMemoryError`异常。
除了 `StackOverFlowError` 错误之外，栈还可能会出现`OutOfMemoryError`错误，这是因为如果栈的内存大小可以动态扩展， 那么当虚拟机在动态扩展栈时无法申请到足够的内存空间，则抛出`OutOfMemoryError`异常。

简单总结一下程序运行中栈可能会出现两种错误：

- **`StackOverFlowError`：** 若栈的内存大小不允许动态扩展，那么当线程请求栈的深度超过当前 Java 虚拟机栈的最大深度的时候，就抛出 `StackOverFlowError` 错误。
- **`OutOfMemoryError`：** 如果栈的内存大小可以动态扩展， 如果虚拟机在动态扩展栈时无法申请到足够的内存空间，则抛出`OutOfMemoryError`异常。
