推荐答案

IndexOutOfBoundsException ：抛出该异常表示某种索引（例如数组，字符串或向量）超出了范围。

IndexOutOfBoundsException :Thrown to indicate that an index of some sort (such as to an array, to a string, or to a vector) is out of range.

ArrayIndexOutOfBoundsException ， StringIndexOutOfBoundsException

ArrayIndexOutOfBoundsException ：抛出该异常表示已使用非法索引访问了数组。索引为负或大于或等于数组的大小。

ArrayIndexOutOfBoundsException: Thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array.

StringIndexOutOfBoundsException ：由String方法抛出，以指示索引为负数或大于字符串的大小。对于某些方法，例如charAt方法，当索引等于字符串的大小时也会抛出此异常。

StringIndexOutOfBoundsException:Thrown by String methods to indicate that an index is either negative or greater than the size of the string. For some methods such as the charAt method, this exception also is thrown when the index is equal to the size of the string.
