POS SYSTEM

[Terdia]

Hello please I need urgent assistant to write a multi-user point of sales system in java that allows the cashier to key in all purchased product codes, quantities and then output a receipt.

Please where do I start from I am new to programming, it is a command line system

thanks

Starting with a complex multi-platform client-server system that handles money is not a good place to start with programming. You probably should buy or rent one.

Thanks I have manage to do something the application is running now but how can I used thread to turn it in a muilti-user system?

here is the code so far

import java.util.*;
public class PointOfSales{

public static void main(String [] args){

System.out.println("\f");
Scanner input = new Scanner(System.in);
System.out.println(" XTREME POS SYSTEM \n");

do{
System.out.println("Enter product code [0 - 9] and qauntity [0 - 9] then press 0 to calculate and print receipt");



while(true){

System.out.print("\nProduct code = ");
String code = input.next();

System.out.print("Quantity = ");
int qty = input.nextInt();


if((code == SENTINEL) || (qty == 0)){
break;
}

double pr = getPrice(code);
String ds = getDesc(code, qty);

double check = pr * qty;
total += check;
output += ds;
}

System.out.println("\n");
System.out.println(output);
System.out.println("Total is: " + total);
System.out.println("Do you wish to continue? (yes or no)");
condition = input.next();

}while(condition.equals("yes"));
}


private static double getPrice(String thecode){

String code = thecode;

if(code.equals("0011")){

price = 176.2;
}

else if(code.equals("0012")){

price = 156.7;
}

else if(code.equals("0013")){

price = 186.2;
}

else if(code.equals("0014")){

price = 256.3;
}

else if(code.equals("0015")){

price = 216.8;
}

return price;
}



private static String getDesc(String desc, int q){

String description = desc;
int quantity = q;

if(description.equals("0011")){

descs = "Product Code -: 0011 \nQuantity -: " + quantity + " \nPrice -: $176.2\n\n";
}

else if(description.equals("0012")){

descs = "Product Code -: 0012 \nQuantity -: " + quantity + " \nPrice -: $156.7\n\n";

}

else if(description.equals("0013")){

descs = "Product Code -: 0013 \nQuantity -: " + quantity + " \nPrice -: $186.2\n\n";
}

else if(description.equals("0014")){

descs = "Product Code -: 0014 \nQuantity -: " + quantity + " \nPrice -: $256.3\n\n";
}

else if(description.equals("0015")){

descs = "Product Code -: 0015 \nQuantity -: " + quantity + " \nPrice -: $216.8\n\n";
}

return descs;
}


static final String SENTINEL = "0";
static String condition = "no";
static String descs;
static String output = "==+++++++++++++++++++++++++++++++++++++++++++++++++++++==\nProduct Detials\n==+++++++++++++++++++++++++++++++++++++++++++++++++++++==\n\n";
static double total;
static int cal;
static double price;

}
