incompatible types: possible lossy conversion from double to int. I don't know why i'm getting this error message

casting, double, int, java

Solution

`Math.floor` returns a `double`, not an `int`. Modify your `randomInteger` method:

private int randomInteger(int min, int max) 
{
    min = (int) Math.ceil(min);
    max = (int) Math.floor(max);
    return (int) Math.floor(Math.random() * (max - min));
}

Alternatively, use `nextInt` from the `Random` class

Problem

``` private void buildingComposotion () { for (int i=1; i<=randomInteger(3,6); i++) { int numberOfStories = 2; buildingFrame(numberOfStories); buildingWindows(numberOfStories); } } private int randomInteger(int min, int max) { min = (int) Math.ceil(min); max = (int) Math.floor(max); return Math.floor(Math.random() * (max - min)); } ``` The error, "incompatible types: possible lossy conversion from double to int." is on line 15.
