Your statement "not with rectangles AKA things like circles and prefurable not something too complicated" is completely confusing. What do you mean?

The easiest way to do collision detection without writing an algorithm yourself is to surround your object with a shape, a Rectangle, Ellipse2D, etc. They all inherit contains() and intersects() from Shape.

the Polygon class also has an intersect() method
All shapes can be translate to polygons. More the polygons have points more precise is the intersection
