java_io_FileNotFoundException使用方法如下

问题分析：
这是数组存储异常，当试图将类型不兼容类型的对象存入一个Object[]数组时将引发异常。
解决方案：
当试图将类型不兼容类型的对象存入一个Object[]数组时将引发异常，建议根据堆栈信息修改存储对象类型。
代码示例：

1. [backcolor=transparent]class[backcolor=transparent] [backcolor=transparent]Father[backcolor=transparent]{}
3. [backcolor=transparent]class[backcolor=transparent] [backcolor=transparent]Son[backcolor=transparent] [backcolor=transparent]extends[backcolor=transparent] [backcolor=transparent]Father[backcolor=transparent]{}
5. [backcolor=transparent]...[backcolor=transparent] [backcolor=transparent]...
7. [backcolor=transparent]public[backcolor=transparent] [backcolor=transparent]void[backcolor=transparent] handleArrayStoreException[backcolor=transparent](){
8. [backcolor=transparent]      [backcolor=transparent]Father[backcolor=transparent][][backcolor=transparent] fathers[backcolor=transparent]=[backcolor=transparent]new[backcolor=transparent] [backcolor=transparent]Son[backcolor=transparent][[backcolor=transparent]3[backcolor=transparent]];
9. [backcolor=transparent]      [backcolor=transparent]// 此处会抛异常
10. [backcolor=transparent]      [backcolor=transparent]try[backcolor=transparent] [backcolor=transparent]{
11. [backcolor=transparent]        [backcolor=transparent]// 无法存父类对象，只能存子类对象
12. [backcolor=transparent]      fathers[backcolor=transparent][[backcolor=transparent]0[backcolor=transparent]]=[backcolor=transparent]new[backcolor=transparent] [backcolor=transparent]Father[backcolor=transparent]();
13. [backcolor=transparent]    [backcolor=transparent]}[backcolor=transparent] [backcolor=transparent]catch[backcolor=transparent] [backcolor=transparent]([backcolor=transparent]ArrayStoreException[backcolor=transparent] e[backcolor=transparent])[backcolor=transparent] [backcolor=transparent]{
14. [backcolor=transparent]      e[backcolor=transparent].[backcolor=transparent]printStackTrace[backcolor=transparent]();
15. [backcolor=transparent]    [backcolor=transparent]}
17. [backcolor=transparent]      [backcolor=transparent]// 正确的代码
18. [backcolor=transparent]      [backcolor=transparent]Father[backcolor=transparent] father[backcolor=transparent]=[backcolor=transparent]new[backcolor=transparent] [backcolor=transparent]Father[backcolor=transparent]();
19. [backcolor=transparent]      [backcolor=transparent]Son[backcolor=transparent] son[backcolor=transparent]=[backcolor=transparent]new[backcolor=transparent] [backcolor=transparent]Son[backcolor=transparent]();
20. [backcolor=transparent]      [backcolor=transparent]if[backcolor=transparent]([backcolor=transparent]son [backcolor=transparent]instanceof[backcolor=transparent] [backcolor=transparent]Son[backcolor=transparent]){
21. [backcolor=transparent]          [backcolor=transparent]// 可以存进数组
22. [backcolor=transparent]        fathers[backcolor=transparent][[backcolor=transparent]1[backcolor=transparent]]=[backcolor=transparent]son[backcolor=transparent];
23. [backcolor=transparent]      [backcolor=transparent]}
24. [backcolor=transparent]      [backcolor=transparent]if[backcolor=transparent]([backcolor=transparent]father [backcolor=transparent]instanceof[backcolor=transparent] [backcolor=transparent]Son[backcolor=transparent]){
25. [backcolor=transparent]            [backcolor=transparent]// 无法存进数组
26. [backcolor=transparent]        fathers[backcolor=transparent][[backcolor=transparent]2[backcolor=transparent]]=[backcolor=transparent]father[backcolor=transparent];
27. [backcolor=transparent]      [backcolor=transparent]}
28. [backcolor=transparent]    [backcolor=transparent]}
