java - I am writing a program for a class that involves inputting and keeping track of totals and sub totals for each individual person in a restaurant -

package restaurantmenu;  import java.util.scanner;  public class restaurantmenu {      public static void main(string[] args) {          scanner input = new scanner(system.in);          string[] itemname = { " ", "soup", "wings", "burger", "chicken sandwich", "fries", "pie", "ice cream",                 "soft drink", "coffee" };         double[] itemprice = { 0, 2.50, .15, 4.95, 5.95, 1.99, 2.95, 2.99, 1.50, 1.00 };          double grandtotal = 0;         double total = 0;          system.out.println("how many people in party? ");         int partynumber = input.nextint();          (int = 0; < partynumber; i++) {             system.out.println("discount type:");             system.out.println("--------------");             system.out.println("1: child");             system.out.println("2. teen");             system.out.println("3: senior");             system.out.println("4. none of above");             int discount = input.nextint();              (int k = 0; k < itemname.length; k++) {                 system.out.println(itemname[k] + "   ");             }              (int j = 1; j <= 3; j++) {                  system.out.println("please select menu item: ");                 int itemnum = input.nextint();                  if (itemnum == 2) {                     system.out.println("how many want? ");                     int amount = input.nextint();                     itemprice[2] = itemprice[2] * amount;                 }                  total = total + itemprice[itemnum];              }              system.out.println(total);              if (discount == 1)                 total = total * 0;             else if (discount == 2 || discount == 3)                 total = total * .75;             else                 total = total + (total * .05);              grandtotal = total;          }         system.out.println(grandtotal);     } } 

so, i'm thinking total not resetting upon jumping out of second loop, don't know if need to. i'm wondering why can't total track properly, output grandtotal, , discount multiple people. if needs input data provided me teacher let me know.

at end of englobing loop, reset total, , grandtotal must add total.

grandtotal += total; total = 0;
