package com.company;
public class VehicleApp {
public static void main(String[] args) {
Vehicle[] vehicles = new Vehicle[3];
vehicles[0] = new Vehicle();
vehicles[0].setRegNo("21313");
vehicles[0].setCarMake("Audi");
System.out.println(vehicles[0]);

vehicles[1] = new Vehicle();
vehicles[1].setRegNo("56363");
vehicles[1].setCarMake("Nissan");
System.out.println(vehicles[1]);

vehicles[2] = new Vehicle();
vehicles[2].setRegNo("57786");
vehicles[2].setCarMake("BMW");
System.out.println(vehicles[2]);


}
}



package com.company;
public class Vehicle {
private String regNo;
private String carMake;
/**
Constructs a Vehicle object
*/
public Vehicle() { }
/**
Constructs a Vehicle object
@param regNo the reg no of the vehicle
@param carMake the carMake of the vehicle
*/
public Vehicle(String regNo, String carMake) {
this.regNo = regNo;

}
/**

@return regNo of the vehicle
*/
public String GetregNo (){

}
/**
Returns the car make of the vehicle
@return carMake of the vehicle
*/
public String getcarMake (){

}
/**
Sets the regno to the parameter value
@param newregNo the reg no of the vehicle
