Question

I am getting an error on this line:

public int[][] mySpiros;

The error is as is:

Field Spirograph.myList.mySpiros is never assigned to, and will always have its default value null.

Now this line is written in a class. I only wanted to create a double array so I can store my future parameters for each drawings (spirographs) generated by the user.

Edit: Seems like instantiating multiple arrays of integers is not Microsoft’s favorite action:

You’re creating array of arrays so you need to instantiate arrays like:

public int[][] mySpiros;

//create three reference variables to hold array references
mySpiros=new int[3][];

mySpiros[0]=new int[4];
mySpiros[1]=new int[] {11,22,33,44};
mySpiros[2]=new int[40];
