Answer 1

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]);


}
