Answer:
import java.util.*;
class Main
{
public static void main(String[] args)
{
System.out.println("Enter integers and 0 to exit");
Scanner a1=new Scanner(System.in);
System.out.println(add(a1));
}
public static int add(Scanner a1)
{
int total = a1.nextInt();
if (a1.hasNextInt())
{
total =total +add(a1);
}
return total;
}
}
Explanation:
The only thing that needs explanation here is hasnextInt. This returns true if entered number is integer and false if entered is not an integer. And rest is as shown in the program.
Most of the cars or other vehicles in the United States regularly have tanks that can hold up to 12 gallons worth of gas. The price of gas in not consistent. Sometimes prices are high and sometimes prices are low. Just like to day the price of a gallon is worth $2.2. But in an average, gas costs $3.8 per gallons. Therefore, on a regular basis a standard American which can hold 12 gallons costs $46.2.
