exception - Java.Lang.Stringindexoutofboundsexception index out of range (0) -


Each time the program tries to loop, the error "java.lang.stringindexoutofboundsexception" comes up and put

key = choice.charAt (0);

Do anyone know why this happens? I am new to programming and this is stumped to me. Thanks for any help. Any solution to this problem will be amazing

import java.util.Date; Import java.util.Scanner; Public class assignment 2 {public static zero main (string ARGS []) {Scanner = New scanner (system.); Date = new date (); Double wine = 13.99; Double beer 6 = 11.99; Double beer 12 = 19.99; Double beer 24 = 34.99; Double Spirient = 25.99; Double Spirit 1000 = 32.99; Int drink = 0; Double winital = 0.0; Double Grandotle = 0.0; Double GST = 0.0; String full = ""; String options; Four = ''; Double deposit 750 = 0.10; Double deposit = 1000 = 0.25; System.out.println ("------------------------------ \ n" + "*** Joshi's Liquer Mart You are welcome *** \ n today's date is "+ date"); Println ("----------------------------- ------- \ n "); Do {if! = 'W' & amp; ki! = 'B' & amp; amp; amp; ki! = 'S') {System.out. Print ("Wine is $ 13.99 \" Bayer 6 pack is $ 11.99 \ n "+" Beer 12 pack is $ 1.99 \ "Beer 24 Pack $ 34.99 \" Safijets is 750 ml $ 25.99 \ n "+" Spirits is 100ml $ 32.99 \ nImons are being purchased? \ N "+" For wine for beer, for beer and S spirits for B, or to leave x: ");} likes = k.nextLine ( ); = Liked Art (0); Switch (Key) {Case 'W': {System.out.print ("How many bottles are being purchased:"); Wineparchs = KNXIN (); Println (); Wineot = Wine * Wine purchase; GST = Vintotal * 0.05; Vintotal + = GST; System.out.println ("+ + + + + + + Waste slip +", which includes "+" GST and Deposit "+ Vinal"); System.out.print ("Is this customer order complete?" (Y / N) "); Complete = k.next (); break; }}} While (of! = 'X');

error means that the index "0" is outside the string limit To correct the user typed in any input, such as when you start the program and press the enter key, just add the following lines of code: 

  likes = k.nextLine (); If (help.size ()> 0) {// process results} other {// ignoring the result}

I know that it helps!

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
