Кода който съм написал е следния :

import java.util.Scanner;

public class Petshop {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int dog = Integer.parseInt(scan.nextLine());
int cat = Integer.parseInt(scan.nextLine());
double dogPrize = dog * 2.50;
int catPrize = cat * 4;
System.out.println( dogPrize + catPrize + "lv.");

}
}

Моля, за съдействие и обяснение къде и какво бъркам. 

Благодаря ви предварително.
