Thread: How do I add an index in the middle of an ArrayList?

Hello,

I'm having some trouble with adding a specific index from one ArrayList to another. In this case, the index needs to get in the exact middle. I've been trying to solve this with the Math.ceil function, but I get the error:

'incompatible types: possible lossy conversion from double to int'

How can I pass this error, and have the code work?

Thanks!

 public void changeToRow1(Person name)
    {
        if(name.hasVIPpass() == true && maxInRow1<= 8)
        {
            row1.add(Math.ceil(row1.size()/2.0), (name));
            row2.remove(name);
            maxInRow1++;
        }
        else
        {
            System.out.println("Stay in your own row please!");
        }
    }
