Call object - syntax

**überfuzz** · 02-06-2011, 08:58 PM

Hi all!

I'm only just started with java. When I thinker with some simple classes/objects I don't know how to call/use objects in my code. Let me clarify with an example.

Example:
File: Car.java

Java Code:

public class Car(){ heaps of code...}

File: Race.java

Java Code:

public class Race()
{
  //How do I call Car in the constructor?
  //How do I call Car in a method? Let's say I want to create an array of the type Car. 
  Car[] arrayOfCars = new Car[random];
  //etc...
}

Sorry if I ask stuff like this. I just need to get started on this, bear with me.

Edit
When I do this:

PHP Code:

Object [] array_containing_objects = new Object[10];

I get this message for DrJava;

Java Code:

Static Error: Undefined name 'array_containing_objects'

Thanks!

Argh, it seems I missed out on what I did wrong... I can create an Object from an external file. This works:

Java Code:

ExternalObject TestObject = new TestObject();

I guess I do something wrong when I try to create an array with the type of ExternalObject in my code.

How should I do if I like to have an array containing objects..?

Edit, I found the syntax of how create and work with an array of objects.
