Array initialization with default constructor

Question

public class Sample
{
     static int count = 0;
     public int abc;
     public Sample()
     {
        abc = ++Sample.count;
     }
}

Answer 1

The problem is that by declaring that array, you never allocated space for each object. You merely allocated space for 100 objects of type Sample. You'll have to call the constructor on each yourself.

To elaborate:

Food[] foods = Food[100];
for (int k = 0; k < foods.length; k++) {
   foods[k] = new Food();
}

An interesting work around might be a factory function. Consider attaching this to your Sample class.

public static Sample[] getInstances(int aNumber) {
    Sample[] sample = Sample[aNumber];
    for (int k = 0; k < sample.length; k++) {
       sample[k] = new Sample();
    }

    return sample;
}

Hides the blemish, a bit - providing this is a useful function to you.
