NullPointerException

[6 Replies]

Hi I was wondering if someone could help me:

I'm trying to get a Legend string inserted individually into each box created (N) on the below code but coming across a few problems:

Here is my Class_Square, followed by the main code.

Errors

Line 1 of my class gives me a NullPointerException error

Line 2 of the main code gives me cannot convert to char to string error

Can anyone help on where i'm going wrong?

Thanks
1. SBB2.this.text(this.Legend, this.Cx, this.Cy);
3. localSquare.Legend = this.Legend.charAt(i);

Odd or Even number

Can someone tell me how I would go about writing code to check whether an integer is odd or even?

Thanks
