Project For Reservations At A Restaurant - Set Array In Parameters
May 3, 2015Okay 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.
Declaring Object Using Interface Implemented By Its Class Vs Declaring Object Using Class
Apr 8, 2014Suppose you have a generic Dog class of the pet type that implements a DogInterface of the pet type. What is the difference between;
DogInterface<pet> Rex = new Dog<pet>();
and
Dog<pet> Tye = new Dog<pet>();
In what situations might you want to use Rex instead of Tye?

2. Room Rate (Suite - $500per night, Deluxe - $300per night)
3. Both rooms can accomodate 2adults and 2childs
4. Checkin time: 2pm, Checkout 11am
5. Room status = occupied once guest checkin, Room status = vacant once guest checkout
6.For checking require (ID,Full Name,Address,Nationality,Flight no/Vehicle Reg no,number of people,check-in date, check-out-date,payment detail
7.Front desk search the vacant room to be assigned to the guest
Functions:
1. View all rooms
2. Add Customer to a room
3. Display available room
4. Delete customer from a room
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

High Scores On Table - Shifting Elements In Array To The Right
Dec 7, 2014I'm trying to write a program that asks a user how many high scores they want on a table, then the users types the inital highscores and is repeatedly asked to place more high scores on the table, which if larger than any existing high score, will take its place and shift the other scores down.

How can I use an array with 4 values in Table Cell?
Declaring Variable And Using Getter
Jul 2, 2014I have question on best practice on declaring variable and using getter. Is there any performance issue if I used getter every time to access the properties values or Is better to use getter once, store in variable then use that variable whenever needed.
a) What is the best practice?
b) Also what if getter in deep level e.g. myTopObj.getInnerOne().getInnerTwo().getProp();
Option 1
Java Code:
var myProp = obj.getProp();
x = myProp;
y = myProp mh_sh_highlight_all('java');
Option 2
Java Code: x = obj.getProp();
y = obj.getProp(); mh_sh_highlight_all('java');
Declaring Variables In GUIs
Aug 25, 2014In most of the GUI examples, it declares the variables right at the start as private.
public class KiloConverterWindow extends JFrame
{
private JPanel panel;
private JLabel messageLabel;
private JTextField kiloTextField;
private JButton calcButton;
private final int WINDOW_WIDTH = 310;
private final int WINDOW_HEIGHT = 100;
In one example though, it declares and creates the different objects in the constructor.
public BorderWindow()
{
setTitle("Border Layout");
setSize(WINDOW_WIDTH, WINDOW_HEIGHT);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new BorderLayout());
JButton button1 = new JButton("North Button");
JButton button2 = new JButton("South Button");
JButton button3 = new JButton("East Button");
JButton button4 = new JButton("West Button");
JButton button5 = new JButton("Center Button");
Now what I assume, is that for the second example snippet, because it's sole purpose is to show you the Border layout, there are no events tied to any buttons, and there is no data, other than the names of the buttons. With the first snippet, it's purpose was to show the kilometer to miles converter using a GUI. The purpose of making it private is to prevent the data from being altered from outside code. If I have the right idea, I feel like they should have continued to keep their examples consistent.
Declaring Parameters - Use Void For
Mar 1, 2015I want to have parameters that I use the "void" for, in other words it doesn't return anything.

}
void takeTwo (int x, int y) {
int z = x + y;

Declaring Static Int - Illegal Modifier For Parameter
Feb 15, 2014I accidentally wrote a code differently than what I should've, and I got these errors :
"Illegal modifier for parameter a; only final is permitted"
"Illegal modifier for parameter b; only final is permitted"
"Illegal modifier for parameter c; only final is permitted"
The code that I wrote and gave these errors:
Java Code:
class Math {
public static void main(String[] args) {
static int a = 11;
static int b = 35;
static int c = 29;
//the rest of the code below
[Code] ....
I noticed that I can declare "static int" only under "class Math" and not under "public static void main".(I had to remove "static" if declaring int under "public static void main");

Method Implementation Declaring Exception Other Than That Declared In Interface
Aug 31, 2014The 2 minute drill from page 69 SCJP kathy and bert book, says regarding Interfaces, that - "A legal nonabstract implementing class must not declare any new checked exceptions for an implementation method."
When I try the below given code in eclipse , it does not throw any errors . (Here I have tried to throw NullPointerException from testFunc whereas the interface function throws IllegalStateExc)
package abstracttesting;
public class StaticCheck implements check{
public void testFunc() throws NullPointerException{
// TODO Auto-generated method stub
} public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
interface check{
void testFunc() throws IllegalStateException;
}
Declaring Enums - Could Not Find Or Load Main Class
Feb 25, 2014I've just started, so right now I'm reading about declaring enums, the book lists the following code
enum CoffeeSize {
//8,10 & 16 are passed to the constuctor
BIG(6), HUGE(10), OVERWHELMING(16);
CoffeeSize(int ounces){ //constructor
this.ounces = ounces;
[Code] .....
I'm assuming that code to be in a same file since enums can be declared within and outside a class, so I saved it into a file named "Coffee.java", it compiles just fine from command line but when I try to execute "java Coffee" it throws "Error: Could not find or load main class Coffee"...

Print Table (array) Where Have X Axis And Y Axis?
Apr 12, 2015I want to print a table (array) where I have an X axis and a Y axis. 16x11. My code is as follows:
int Windchill [] [] = new int [16][11];
{
{60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0, -5, -10, -15} //X
{0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50} //Y
};
The code doesn't work even though it's similar to
int Windchill [][] =
{
{60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0, -5, -10, -15}, //X
{0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50}, //Y
};
if I remember correctly, the 2 are correct just written in different ways.
and I want it to print like this
{60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0, -5, -10, -15},
