Many gas pumps have displays that spin digits $($either analog or digital$)$ while the gas is being pumped into your car's gas tank. The display's digits change to indicate the amount of gas in the tank and the current price.

Write a program that displays the spinning of the digits. Your GasPumpDisplay class will allow you to create a "gas pump" display with a specified number of display places and will allow you to specify the highest digit in use. You will simplify a gas pump display by using a smaller display of only three digits where the digits are in the limited range of $0-4$ inclusive.

public class GasPumpDisplay public GasPumpDisplay $($int numberOfPosition$)\{$

$\}$

public String nextElement $()$

$1$

public Boolean hasMoreElements $()$

$\}$

private int digits;

private GasPumpDisplay tail;

private int currentDigit,

private static final MAX$\_$DIGIT$=4$;

$\}$

public class GasPumpTester $\{$

public static void main $($String $[]$ args$)\{$

GasPumpDisplay d $=$ new GasPumpDislay $(3)$;

$\}$

Output: GasPumpTester prints the following permutations.
