My current setup is only useful once collision has been made; obviously there has to be something better than this?

public boolean CollisionCheck(Rectangle rect1, Rectangle rect2) {
   if(rect1.intersects(rect2)) {
      return true;
   }
   return false;
}

How can I do preemptive collision detection?
