Question
PLease, I need help with this Code. PLease create correctly documentations comments for better understanding.
This is the input:
This is what I have so far:
public class Car
{
private String licenceNo;
private int countOfMove;
public String getLicenceNo() {
return licenceNo;
}
public void setLicenceNo(String licenceNo) {
this.licenceNo = licenceNo;
}
public int getCountOfMove() {
return countOfMove;
}
public void setCountOfMove() {
this.countOfMove;
}
}

Programming Assignment #2 (Arrays,) 2. The Car class will have private instance variables that atore the license number and number of timea the car haa been moved, and any methods you d1acover to be neccaaary 3. To get credit, your Garage class mast usc an array (not an ArzayList) of C objects to implement the garage. No credit ill be given if you ak the aaaignment I. The Aasignment the B55aSBAA. Parking Garage contains a 51ngle 1ane that an hold up to ten cara. Ariving cars enter the garage at the rear and are parked in the enpty apace neareat to the front Departing cara exit only from the front unneceaaarily more difficult by uaing more than one array 4. Use defined con tant to set the 5ize of the array. Other than in the constant declaration, the literal 10 ahould not appear in your program If a cu8tomer needs to pick up a car that is not neare t to the exit, then all cora blocking 1ts path are moved out temporarily, the customer cars are estored in the ordez they were in originally Whenever a car departs, all cars behind it in the garage are moved 5. To handle the arrival and departure of cach car, your Garage claas must implement separate methods aive) aned depart each of which retur a String ahowing the reault , r î driven out nd the other r of the operation (aee above) 6.
