non primitive arrays

[frosty]

hi, i have an exam ICT tomorrow but i am stuck with one thing that i can't seem to understand, its about NON-primitive arrays. Is it possible to explain the java code with a easy example? i work with Jcreator.

thanks in advance

There is nothing special about arrays of objects (non-primitives) given a type T, an arrays of references to T is defined as follows:

T[] array= new T[42];

This gives you 42 elements of type T and all of them are null. You have to set them to a non-null value yourself. You can also do that in an array initializer:

T[] array= { new T(1), new T(2),  new T(3) };

This assumes that the type T has a constructor that takes one int argument. This defines an array of three T type objects, each instantiated in the array initializer list.

kind regards,

Jos explained it but I will try easier again

say you have a class called Player

well if you want an array of Player then there is no big difference than those of primitive types

Player [] player=new Player[5]; // this gives you 5 Player types uninitialised of course.

to initialise just do this
player[0]=new Player(); // if player has a overrriden constructor just add the arguments

you could also use a for loop to initialise the whole array of Player objects.
