    Default What should I snip off of this code?

    Hey! I was wondering which part of this code should be snipped to JUST have the barcode maker?

    import java.util.Scanner;
     
    public class postal
    {
        /**
            Here is a constructor
        */
        public int num2;    // 10000 digit
        public int num3;    // 1000 digit
        public int num4;    // 100 digit
        public int num5;    // 10 digit
        public int num6;    // 1 digit
        public int checkDig; // check digit
        public static int num;
        public static String temp;
        public static int menu;
        public static int zip;
        public static String bar0;
        public static String bar1;

        public static String str;
        public static int numb;
     
        public postal()
        {
            zip = 0;
            /**

    while( zip < 01001 && zip > 99950 ) //You should use ampersands instead of bars because your saying its less than and greater than. 
            {
                System.out.println("**** ERROR ****");
                System.out.println("The ZIP code must be between 01001 and 99950");
                System.out.println("Please,enter the correct zip : ");
                zip = sc.nextInt();
            }

    He wants it to mean less than or greater than. (I would remove the leading 0 in 01001)

    --- Update ---

    Start with the main method and see where it's calling the method that does the other things. I believe the bar-code interpreter method is called 'devide'.

    You also have to remove the other options from the menu. You can either disable them or just remove that particular function. Comment things out one thing at a time, so it doesn't stop working altogether.
