Question

Here is my code:

import java.util.Scanner;

public class BankAccount1
{
public static void main(String[] args)
{
    Scanner input = new Scanner(System.in);

    char pickup;
    char size;
    char type;
    String name;

    double cost=0.0;
    int i;


    for (i=0; i<2; i++)
    {
    System.out.println("What is your name?");
    name = input.nextLine();

    System.out.println("size of pizza: ");
    size =  input.next().charAt(0);

    System.out.println("type of pizza: ");
    type = input.next().charAt(0);

    System.out.println("pick up or delivery?");
    pickup = input.next().charAt(0);


    if(size == 'S' || type == 'V') {cost = 10.0;}
    else if(size == 'M' || type == 'V') {cost = 12.25;}
    else if(size == 'L' || type == 'V') {cost = 14.50;}
    else if(size == 'S' || type == 'C') {cost = 7.0;}
    else if(size == 'M' || type == 'C') {cost = 8.0;}
    else if(size == 'L' || type == 'C') {cost = 9.0;}


    if(pickup == 'D'){
    cost=cost+1.50;
    System.out.println("Name: "+name+". Your cost is: "+cost);}
    else { 
    System.out.println("Name: "+name+". Your cost is: "+cost);}


    } 

}

}

I have a for loop in my code, and it asks the name, size, type and pickup. The first time it is run, it asks all fields to be entered, but for the 2nd time, the name field does not let me input the name for some reason, it prints the “What is your name?” but it does not let me enter the name…? can someone tell me why?
Thanks.

this is what it looks like: https://i.stack.imgur.com/eb1BA.jpg

Answer 1

Due to the fact that

input.next()

does not consume newline characters, these get passed passed back to your loop and does not allow a value to be entered. You would need to add:

for (i = 0; i < 2; i++) {
   // existing input.next() statements in here
  ...

   input.nextLine();
}

at the end of the for loop to fix.
