7.5.1. ArrayIndexOutOfBoundsException and IndexOutOfBoundsException

As shown in figure 7.17, ArrayIndexOutOfBoundsException and IndexOutOfBounds-Exception are runtime exceptions, which share an IS-A relationship. IndexOutOfBoundsException is subclassed by ArrayIndexOutOfBoundsException.

Figure 7.17. Class hierarchy of ArrayIndexOutOfBoundsException

An ArrayIndexOutOfBoundsException is thrown when a piece of code tries to access an array out of its bounds (either an array is accessed at a position less than 0 or at a position greater than or equal to its length). An IndexOutOfBoundsException is thrown when a piece of code tries to access a list, like an ArrayList, using an illegal index.
