(b) Write the BicycleInventоry methоd chоoseOne. The method rаndomly selects one bicycle from аn аrray of at most n bicycles for which the bicycle type is equal to the type parameter and the bicycle assembly status is equal to the assembled parameter. The method returns the randomly selected bicycle if the array contains at least one bicycle matching the criteria or returns null if there are no matching bicycles. Each matching bicycle in the array must have an equal chance of being selected.   Assume that getChoices works as specified, regardless of what you wrote for part (a). You must use getChoices appropriately to receive full credit.   Write method chooseOne. /** Returns a randomly selected bicycle, as described in part (b)  *  Precondition: n > 0  */ public Bicycle chooseOne(int n, String type, boolean assembled)
