Java有2类错误类：error和exception。下图是Java错误类的结构图：



exception比较好捕获，error就比较难捕获了，如OutOfMemoryError和StackOverflowError。
下面列出几种常见的error表述：

Error                                 Package      Description

Error                             java.lang      Error is the parent class for all other error objects.

NoClassDefFoundError      java.lang      A class definition could not be found.

NoSuchFieldError              java.lang      A specified field could not be found.

NoSuchMethodError          java.lang      A specified method could not be found.

OutOfMemoryError           java.lang       The Java Virtual Machine that you're running has run out of memory.

StackOverflowError           java.lang      The memory stack is full. You are calling programs too deep, or using too large (or too many) variables in your path of execution.

VirtualMachineError            java.lang      VirtualMachineError is the parent class to several serious environment errors. It indicates that some serious resource problem exists on the host Java machine.
