Array of objects, as an Instance variable

[blaklite]

Hullo,

firstly hello to you all..

Secondly, im nedw(ish) to java and prone to doing silly things so i'm probably doing it all wrong BUT

I want to be able to have a class that has as one of its members as an array of objects.

When the class is instanced I want the constructor to assign values to each of the items in the array, using a method of the class in the array.

Like

class MyClass extends otherClass {

public MyClass (x,y,w,h) {
super(x,y)
...etc other constructor stuff

array[0].objectMethod(x,y);
array[1].objectMethod(x+(2*w),y);

... etc for the other array members

}


//Then a Get method for the data
public ObjectType getArray(idx) {
return array[idx];
}

//Declare the class data member like this ??
private ObjectType array[];
}

Thats the general form I want BUT as the "ObjectType" object has not been created I cant call the method to add the members to the array?

Would I do something like..

ObjectType myType = new ObjectType[3];

before calling the methods of the array members? but if so where and how could I call MyClass.getArray(x) ??

I have tried searching/googling but cant find the right words to use in my search, any help would be appreciated...

many thanks

b

class MyClass extends otherClass {

  private ObjectType[] array;

  public MyClass (int x,int y,int w, int h) {
    super(x,y)
    ...etc other constructor stuff

    array = new ObjectType[3];
    array[0] = new ObjectTypeA(x,y,w,h);
    array[1] = new ObjectTypeB(x,y,w,h);
    array[2] = new ObjectTypeC(x,y,w,h);
  }

  //Then a Get method for the data 
  public ObjectType getArray(int idx) {
    return array[idx];
  }

}

public class ObjectTypeA extends ObjectType {

  public ObjectTypeA(int x, int y, int w, int h) {
     super(...whatever is appropriate here...);

     ...initialization specific to this type
  }

}

...same thing for ObjectTypeB, ObjectTypeC, etc.
