Question

The UML for an Instantiable class called Vehicle is shown below:

Write an application program that uses an array to create three Vehicle objects with appropriate data. Add code to display the contents of the array.



Vehicle

-regNo:String
-carMake:String

+Vehicle()
+Vehicle(String, String)
+setRegNo(String):void
+setCarMake(String):void
+getRegNo():String
+getCarMake():String
+toString():String

Answer 1

public class Main {
public static void main(String[] args) {
Vehicle array[] = new Vehicle[3];
array[0] = new Vehicle("BD51SMR", "Audio");
array[1] = new Vehicle("BD51SMR", "Ford");
array[2] = new Vehicle("UKPL8TE", "Mercedes");
for(int i = 0; i < array.length; i++){
System.out.println(array[i]);
}
}
}




public class Vehicle {
private String regNo;
private String carMake;

public Vehicle(){

}

public Vehicle(String regNo, String carMake){
this.regNo = regNo;
this.carMake = carMake;
}

public void setRegNo(String regNo){
this.regNo = regNo;
}

public void setCarMake(String carMake){
this.carMake = carMake;
}

public String getRegNo(){
return regNo;
}

public String getCarMake(){
return carMake;
}

public String toString(){
return regNo + " " + carMake;
}
}
