Seat Booking System - How To Mark Out Specific Seat User Booked With X Or Such
Apr 20, 2015
I need to write out code for a seat booking system. So far I have the seats displayed but when I ask the user to enter their seat column and row I don't know how to mark out that specific seat they have booked with an X or such? This is what I've done so far.
import java.util.Scanner;
public class show2
{
public static final int column = 20;
public static final int row = 10;
public static void makeReservations(int[][] seatarray, Scanner input)
[Code] ....

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. 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<>();
for (int i=0;i<8;i++){

How Can I differentiate the System classes and user classes in my program written below by another program?
/**
* Employee Class containing all non-primitive data types.
*
*/
class Employee{
private String name;
private String phone;
private Integer age;
private Float salary;
[Code] ....
Any Technique that will decide which one of the fields (Integer, Address, DOB, String, Float) are user defined type. (An outsider class should used that will identify the Java classes and the user-defined classes.)

This program simply adds integers to an ArrayList and then prompt the user if they would like to delete specific numbers that they don't want.
The output that I get when I want to delete numbers like 2 and 4 from 1 2 3 4 5 is 1 2 3 4 5 instead of 1 3 5.
Java Code:
import java.util.ArrayList;
import java.util.Scanner;
public class AL
{
// A regular array like int arr[] has to have its size declare before run-time and it's not dynamic which mean it can not grow or expand on its own.
static Scanner input = new Scanner(System.in);
// You have to use reference types(Integer, Double, Float); not primitive types(int).

So I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect
/*
conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");

How do I move focus from a jcombobox to a specific component say a jtextarea.
My attempt below seems to be moving to a random component not the desired jtextarea.
takenByCombo.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
dayJTArea.requestFocus(); // focust not moving dayJTArea
}
}
});
I applied the above logic to move focus from a specific jtextarea to another jtextarea as seen below and it works as desired.
dayJTArea.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
monthJTArea.requestFocus();
}
}
});

So here we go with my problem:
- from the main class will arrive three variable (String name_used, int level_choose, int level_result)
I have a .txt file with this kind of formatting:
mario 1 1 0 1 0 1
carlo 0 0 0 1 1 0
...
Where I use 1 and 0 in the main for write if the level (you see that the numbers are always sixr? are egual to six level existing) BEFORE is done correct or wrong
- when in the main a user make a level a feedback coming back from the class level saying if the user made the count correctly or wrong. and i wanna replace the value (1 or 0) in the txt file with the new level result.
So i have all what i need as parameters i think.
name_used to look for the correct line in .txt file with .indexOf
level_choosed to go throught the correct index of that line
level_result (1 or 2) to be replaced with the existing one
Java Code:
public void salvaRisultati(String name_used, int level_choosed, int result_of_level) throws FileNotFoundException{
}
} mh_sh_highlight_all('java');

5. Find room from customer name
6. Exit
Files:
One file use to store room info. (to be retrieved by program)
One file use to store rate info. (to be retrieve by program)
One file use to store the booking details (to be created and write by the program).
Currently I have write a program but only compiling and display the output to the console. How to modify my code below to be able to save to the .txt file

I have some problem to understand the way to make this:
In my main class a user can save his name in a txt file (and the system initially will add 6 value equals to 0) than he can choose between 6 level and make it.
example of .txt file data:
mario 0 0 0 0 0 0
carl 0 0 0 0 0 0
AT THIS MOMENT i just made other class and they work, is this new one that is hard for me. I'm trying to make a class that:
1- (first method called verificaRisultati) take name_used and level_choosed from the main and go to check in the .txt file if that level before was done right(1) or wrong(0)
and return something like "before you made this level properly" or "before you made this level incorrectly" AND THEN let the user start with the level.
2- (second method called salvaRisultati) at the end of the level i wanna pass the result (correct/incorrect) to another method of this class that will save the value (1 or 0) associated to the user in the right position.
This is the class that i'm writing:
Java Code:
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
public class ResultUsers {
[Code] ....
I really need some hint and some code example because I'm stuck. How I can take exactly the line with the user name? How I can correctly split the line in an array and then read/modify the value for that level?

I am doing a pretty basic program with a fixed origin city and five destination cities. I am having trouble with entering passenger details. This is what I tried, but then I cannot retain all passenger details to print later on in the final ticket.
System.out.println("Enter flight details of child passengers (below 12 years)");
System.out.println("Enter Name");
for(a = 1; a <= cp; ++a)
{
//cp is number of child passengers, a is loop variable
String name = br.readLine();
System.out.println("1. " + name);
}

I am trying to have a program go on one of the stock trading websites and read the number a stock or currency is at and display or save it. I have it reading and displaying the binary code but I don't see how to have it find the numbers I would like to get.
On the site you would have to go on the page and click some tabs to trade and maybe the stock you would like, it doesn't really matter what one it returns as this is more just an idea. Although I would like to have it search out a selected stock eventually to take it to the net level. I think my biggest problem is I can't see how to access the stock numbers in the code. I looked for different click events but don't see how to have a program do this.
I do not intend to have it display all the code like it is now. I just did it like that to see what I was getting. I will just have a small toolbar with options and a display.
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;
public class StockTracker {
public static void main(String[] args) {

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.
