Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: I-90 is primary, going east/west. Ex: If the input is: 290 the output is: I-290 is auxiliary, serving I-90, going east/west. Ex: If the input is: 0 or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number.

Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west.

Ex: If the input is:

90

the output is:

I-90 is primary, going east/west.

Ex: If the input is:

290

the output is:

I-290 is auxiliary, serving I-90, going east/west.

Ex: If the input is:

0

or any number not between 1 and 999, the output is:

0 is not a valid interstate highway number.

This is the code I have but for some reason I keep getting errors. what am doing wrong?

import java.util.Scanner;

public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int highwayNumber;
int primaryNumber;

highwayNumber = scnr.nextInt();
}

if (highwayNumber >= 1 && highwayNumber <= 999); {
if (highwayNumber <= 99); {
if (highwayNumber % 2 == 0); {
System.out.println(highwayNumber + " is a primary highway, going east/west");
} else {
System.out.println(highwayNumber + " is a primary highway, going north/south");
}
else {
primaryNumber = highwayNumber;
highwayNumber %= 100;
System.out.println(pimaryNumber + " is an auxiliary highway, serving primary highway " + highwayNumber);
}
} else {
System.out.println(primaryNumber + " is not a valid interstate highway number.");
}
