Arrays of
class type…
lAll arrays of class types must be defined using new
(with an exception of the
String class….)
•list [] array = new list[size];
lBut, such arrays are actually arrays of references to
our objects – not
instances!
•(like an array of pointers in C++)
lIf you forget to allocate objects for the elements, you
will get an exception
lList [] array = new list[] {new list(1), new list (2),
new list(3)};
lOr, do this
explicitly with a loop
lUnlike C and C++, Java allows the return type of functions to be an array
