While I am design the parking system, I am struggling with increment and decrement value. For example, If I type rT, the large number will decrement once. After I choose that again, it's not decrementing anymore.
Can someone body explain it to me, thanks?
Here is my code
import java.util.Scanner;
public class challenge3 {
private static int small = 9;
private static int medium = 24;
private static int mediumHandi = 5;
private static int large = 10;
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
handiCar hc = new handiCar();
rTruck rT = new rTruck();
rCar rC = new rCar();
handiTruck hT = new handiTruck();
bike b = new bike();
int p = 48;
String parkagain = "";
do {
System.out.println("Type your vehicle type: " +
"handiCar hc " +
"rTruck rT " +
"rCar rC" +
"handiTruck hT " +
"bike b ");
String s1 = scanner.nextLine();
if (s1.equalsIgnoreCase("hc")) {
mediumHandi--;
System.out.println("Thank you.");
if (mediumHandi == 0) {
System.out.println("Sorry the parking space has run out");
}
}
else if (s1.equalsIgnoreCase("rT")) {
large--;
System.out.println("Thank you.");
if (large == 0) {
System.out.println("Sorry the parking space has run out");
}
} else if (s1.equalsIgnoreCase("rC")) {
medium--;
System.out.println("Thank you.");
if (medium == 0) {
System.out.println("Sorry the parking space has run out");
}
} else if (s1.equalsIgnoreCase("hT")) {
large--;
System.out.println("Thank you.");
if (large == 0) {
System.out.println("Sorry the parking space has run out");
}
} else if (s1.equalsIgnoreCase("b")) {
small--;
System.out.println("Thank you.");
if (small == 0) {
System.out.println("Sorry the parking space has run out");
}
}
System.out.println("Number of small parking " + small);
System.out.println();
System.out.println("Number of large parking " + large);
System.out.println();
System.out.println("Number of medium parking "+medium);
System.out.println();
System.out.println("Number of handi meduim " + mediumHandi);
System.out.println();
System.out.println("Type your vehicle type: " +
"handiCar hc " +
"rTruck rT " +
"rCar rC" +
"handiTruck hT " +
"bike b or no ");
parkagain = scanner.next();
}while (
(parkagain.equalsIgnoreCase("rT") ||
parkagain.equalsIgnoreCase("hc")||
parkagain.equalsIgnoreCase("rC")||
parkagain.equalsIgnoreCase("hT")||
parkagain.equalsIgnoreCase("b") ||
p <= 48 )
);
System.out.println("Thank you!");
scanner.close();
}
public static class handiTruck {

public static class rTruck {
}
public static class rCar {

public static class handiCar {

public static class bike {

}
