Array Constructor

I am trying to write code for a class that has a 40element array in it and i want to use the 2nd set of code to just input the numbers and print it out for now. I have to do a bunch with the ints later but i cannot figure out how to write the constructor.
I am not sure if I have given enough information for someone to help, but I do not know what else to do. I have spents hours looking at this. Thanks for your help.


public class HugeInteger
{
//Instance Variables
int[] hugeArray=new int [41];
//constructor
HugeInteger(
{

}//End Constructor
}//End Class

*************************
{
public static void main(String args[])
{
// smaller numbers
HugeInteger i = new HugeInteger(9999);
HugeInteger j = new HugeInteger(1);
HugeInteger k = new HugeInteger(-9999);
HugeInteger l = new HugeInteger(-1);

System.out.println(i);
}
}

Code:

---

public class HugeIntegerTest
{
    public static void main(String[] args)
    {
        // smaller numbers
        HugeInteger hugeInt = new HugeInteger();
        hugeInt.addElement(9999);
        hugeInt.addElement(1);
        hugeInt.addElement(-9999);
        hugeInt.addElement(-1);

        System.out.println(hugeInt);
    }
}

class HugeInteger
{
    //Instance Variables
    int numberOfElements = 40;
    // The jvm initializes all elemnts to zero by default.
    int[] hugeArray=new int [numberOfElements];
    int index = 0;

    //constructor
    HugeInteger()
    {
        // Check assertion above:
        for(int i = 0; i < hugeArray.length; i++) {
            System.out.print(hugeArray[i]);
            if(i < hugeArray.length-1)
                System.out.print(", ");
            else
                System.out.println();
        }
    }//End Constructor

    public void addElement(int n)
    {
        // Assign element at index to the local variable/
        // arguemnt value "n".
        hugeArray[index] = n;
        // Increment index.
        index++;
        // If the array is full, ie, index > 39
        // do something...
        if(index > numberOfElements-1) {
            System.out.println("array is full!");
            // Next call to this method will cause an
            // ArrayIndexoutOfBoundsException.
            // Start over:
            index = 0;
        }
    }

    public String toString()
    {
        return java.util.Arrays.toString(hugeArray);
    }
}//End Class
