Java does not allow an array with components of a primitive type to be cast to an array with components of a different primitive type, because the cast operation would require a change to the size of the array components. Java does allow an array with components of a reference type to be cast to an array of a different component type as long as the component types can be legally converted based on the rules of reference conversions. Those conversions don't require a change in the size of the array components, because all reference values have the same size.
