Loop Airplane Seating Reservations Until All Seats Taken Or User Hits 0

Nov 11, 2014

I'm writing a classic airplane seating program. The program runs fine except for two things:

1) I want the user to exit the program when 0 is inputted (program also quits when all seats are reserved - this works fine already). Now the program quits when user hits blank line with enter. How to fix this and make 0 the exit key?

2) I would like for there to be a line below the seating chart saying that there are XX number of seats available. When user makes reservations, the line should update every time under the seating chart saying that there are such and such number of seats available. Any pointers on how to implement this?

import java.util.*;
public class OmaAirplane {
public static void main(String[] args) {
System.out.println("Welcome to the seat reservation system!");
char[][] seats = new char [8][6];
ArrayList<String> reservedSeats = new ArrayList<>();

Writing A While Loop To Read Positive Integers From User Until User Enters EOF Character

Feb 24, 2014

import java.util.Scanner;
public class Project_5
{
public static void main (String[] args)
{
Scanner input= new Scanner (System.in);

[code]....

So I'm attempting to have this program take the users input of integers, pressing enter in between each one. If they enter a negative number it lets them know that its invalid. At the end of the program it takes all of the valid integers entered and must add them and average them. I've put the final println in there as a placeholder. If the user types in "6" then presses enter and types in "3" , the output is:

There were 3 valid numbers entered.
The sum of the valid numbers was --- and the average was ---.
There were 0 invalid numbers entered.

It then continues on allowing the user to enter more values. Here is the example output for correct code"

Enter a positive value (EOF to quit): 4
Enter a positive value (EOF to quit): 7
Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 2
Enter a positive value (EOF to quit): -1
The number "-1" is invalid.

Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 0
Enter a positive value (EOF to quit): -4
The number "-4" is invalid.

Enter a positive value (EOF to quit): CTRL-D

There were 6 valid numbers entered.
The sum of the valid numbers was 29 and the average was 4.83.
There were 2 invalid numbers.

Fill A Panel With Seats

Jun 13, 2014

We get a database and some DAO classes. We had to fill a ShowPanel with different shows being given in a theatre, and then when you choose from this you get several dates. Then when you click a date, the seatings appear in the SeatPanel. I got the first part with the shows and dates. But Im stuck at getting the seatings.We have a controller class which calls the shows+dates (this happens in one method). But i always get a nullpointerexception for the seatings. (this happens in a different method). I think i just don't know how to link the chosen show+date with the seatings.For the moment i have

public ArrayList<Seats> getSeating() throws SeatingException{
Show s = shows.getName();
ArrayList<Showdate> showdate = s.getDates();
ArrayList<Place> seating = new ArrayList<Place>();
try{
for (Showdate sd : showdate ){

[code]...

The given class PlaceDao has a static getInstance() method and an ArrayList<model.Place> getSeating(model.Showdate showdate) method.In the next stage i have to try and fill the panel with the seatings, but first i need to be able to call them.

Seating Plan / Chart

Sep 15, 2014

I want to develop a seating chart/plan where people can pick their seat etc. I have developed the UML diagrams etc for this project and want to start with a console version before developing a GUI version. Eventually I want to create a website where users can log in and reserve their seats etc.

Without sounding like I'm putting the cart before the horse, I want to know what Java technologies I will need to develop the final part of the project. At the moment I'm using Eclipse for getting through the Java text books.

Cinema Seating Class

Nov 5, 2014

I just need designing a cinema ticketing program that takes a user's input and either sell tickets, shows the current seating plan and available seats they can purchase, or show hints.This is my main code (separate methods below but not shown here)

public static void main(String[] args) {
displayWelcome();
do {
displayChoiceMenu();
confirmInput = scan.nextLine();

[code]....

This code seems to work fine except for the bit where it asks for price or show seating because I haven't done that yet.However I'm trying to create a separate class the shows the number of seats available and it's meant to look like the image attached.how to use arrays and a class to create this seat arrangement. How to if they reserve a seat and enter the seat number say 'A5', it registers that seat as taken and shows an 'X' to shows it's been reserved and also how to register what category the seat is in - for example if seat A5 is located in gold silver or bronze etc.

Project For Reservations At A Restaurant - Set Array In Parameters

May 3, 2015

Okay I am making a class for a reservation project for reservations at a restaurant. So in the end the whole thing has to take reservations, with a GUI and "book" them. For this class of the project I have to add a item to a array (that being name, phone, and so on). I also have to make a sort method.

private static int indexOfMinInRange(Reservations[] a,int low,int high) {
int max=high;
for(int i=high+1;i>=low;i--)
{if()
{max=i;}}
return max;}

[Code] ....

I am working with IndexOfMinInRange method, I don't know whether to set the return type to Reservations, or to set the array in the parameter to Reservations. This is my main problem.

Unable To Print Out Results Of Program That Calculate Number Of Seats

Nov 11, 2014

I'm trying to print out the results of a program that calculates the number of seats the parties will get in an election.I have to print the partial results and the national results.

I can print te number of seats per party in each constituency, but how can i sum all seats per party in each constituency and print the national results?I'm working with vectors, which I know it might not be the best option, but everything is working, except the fact that I can't loop throuhg the vector and retrieve the total sum per party.Like, adding the seats for labour party in Constituency A and B and C, etc, and print the sum. And do the same for conservative party.Is it possible, or doIhave to create a method in Parties class to solve the problem?

This is what I have now.

for (Parties p : h.geral) {
show += String.format("Constituency - %5s - %5s - %d%n",
p.getConstituency(), p.getParty(), p.getNum_seats());
}

How To Continue With Loop If User Decides To Not Quit

Mar 29, 2015

I have this program I have to write(attached). I am having problems with what the structure will look like. The following what I have so far. The questions I have are in bold.

>get userInput of how many observations

>for(int i = 1; i <= userInput; i++)
>for(int j = 1; j <= 1; j++)
>use a switch(case) method to ask user to select an option(1,2,3)
>example, user chooses option 1:
>ask to input time
>print displacement
>ask user to stop application(Y/N)
>IF "No" is selected --------->>

How do I continue with the loop if user decides to not quit? -- And do I need to put this in each 'case'?

Code Up With A Loop That Prompt User To Say If Program Should Run Again

Sep 10, 2014

I am still relatively new to java and am working on a lab program. I have already met the requirements and am trying to spice my code up with a loop that prompts the user to say if the program should run again. This is what I have so far:

package lab2;
import java.util.Scanner;
public class OrderedPairTest{
public static void main(String[] args){
boolean retry = true;
while(retry == true){

[code]....

However, it is giving me an error after the user inputs "y" in for the answer to run again. What did I do wrong?

Error code is: Exception in thread "main" java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Unknown Source) at lab2.OrderedPairTest.main(OrderedPairTest.java:11)

Simple For Loop - Determine Factorial Of A Number Entered By User

Jun 28, 2014

I'm trying to learn Java and my current project is to write a short program to determine the factorial of a number entered by the user. I haven't looked. There may be a method that will do it, but I want to use a for loop specifically.

What I have compiles just fine. I'm actually pretty thrilled just with that. Here is what I have:

class factorial {
public static void main( String[] args) {
Scanner scan = new Scanner(System.in );
int num;
int product = 1;

public static boolean isBinary(String num) //Check if the entry is binary

for(int i = 0; i < num.length(); i++) {
if(num.charAt(i) != 0 || num.charAt(i) != 1){

Allow User To Enter Roman Numeral And Then Outputs Integer Number Value - While Loop

Feb 7, 2015

Write a program called RomanNumeralHelper that allows a user to enter a roman numeral and then outputs the integer number value. Use a Scanner to accept command line input from the user and continually ask for a roman numeral until the user enters Q (or q) to stop. Your solution should NOT use a switch statement.

Here is sample input / output:

Enter a roman numeral [Q | q to quit]: III
>> 3
Enter a roman numeral [Q | q to quit]: IV
>> 4
Enter a roman numeral [Q | q to quit]: V
>> 5
Enter a roman numeral [Q | q to quit]: Q
Good Bye!

This is what I have so far in my code, but I cant get what the user inputs when I want it to output the number.

import java.util.Scanner;
public class RomanNumber4
{
public static void main(String[] args) {
// obtain input from command window
Scanner input = new Scanner(System.in);

When Type Quit To Close Outer Loop / It Still Runs Inner Loop

Nov 2, 2014

I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.

Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.

After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.

The output of the program should something like this:

John Smith average $850.00
Maria Gonzalez average $90.67
Terry Lucas average $959.00
Mickey Mouse course average $6,050.89
National Bank client average $1,987.67

Code:

public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name = "";
int charge = 0;
int count = -1;
int total = 1;
int grandtotal = 0;
int average = 0;

Prompt User For Integer To Make Sure Length Entered By User Is A Power Of 2

Oct 8, 2014

Basically I need to make a program prompts the user for an integer, check to make sure the length entered by the user is a power of 2 and at least 2. Then I need to convert from base e to base 2 then I need to print the tick marks of a ruler based of the value of the length.

I got the whole converting thing working and the check for a power of 2, that wasn't an issue because it didn't require any recursion. I just don't know how to print out the proper tick mark values.

The way it is supposed to work is that it needs to look like this. Say the user enters 8;

012131210
012345678

Or if the user enters 16;

01213121412131210
01234567890123456

The bottom row is pretty much just the index value, that I print fine.

The top row though is supposed to be the length of the ticks on a ruler, with the middle most value being the value of the conversion from base e to base 2 from above. I can get that printed and what I get just looks like this.

For 8;

000030000
012345678

For 16;

00000000400000000
01234567890123456

As you can see I can get the middle value and the index values below but I don't know how to use recursion to get the right numbers.

Here's my current code.

import java.util.*;
public class TickMarks {
public static void main (String args[]){
Scanner input = new Scanner(System.in);
boolean looping = true;
while(looping == true){
System.out.print("Please enter a length: ");

[Code]...

Now the methods isPowerOfTwo() and printLength() both work fine. However, I'm not sure how to get the left and right side working.

My thoughts were to split the length in half and get a left and right side. I gave both of them arrays so I can keep track of the values. Now as you've seen above I get all zeros and I know it's because that's the default value in an array, I just don't know how to get the proper values.
