Program Won't Produce Output
Feb 15, 2015I'm not sure why, but my program does not produce an output. It is supposed to output total charges.
/*This program provides the user with the price of their monthly internet service based on two inputs.The program asks users which subscription they have. The options are A, B, or C. This is the first input.
The program then will ask the user how many hours they used the internet for. This is the second input.Then, based on the package number, the program will compute their monthly bill. This is the output.
The program calculates the price based on the following prices:
Package A: For $9.95 per month, 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month, 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per month, access is unlimited.*/

Why Server Cannot Produce Same Warning Message Compared To Local Deployed Project
Feb 26, 2014I have a question: I have a Java/JSP/JavaScript project that access back end Oracle database, and provide interaction through tomcat. After we deployed our project, I found one button does not generate necessary warning message from server, but when I deployed and tested our project on local PC, it does generate correct warning message. I am using the same IE, same tomcat version, and I am sure my container is pointing to the same database, and I am sure I using same version of project code by checking with GIT.
Here is the button that I click:
<a target="frmMain" href="RealignServlet?button=REALIGNMENT" title="Procedure Alignment">Align</a><br>
And here is part of the code of RealignServlet:
public class RealignServlet extends SiapBaseServlet {
private static final long serialVersionUID = 1L;
private static final Logger logger = AppLogger.getLogger(RealignServlet.class.getName());
private static final String PROC_QUERY_JSP = "ProcQuery.jsp";
private static final String REALIGN = "REALIGNMENT";
[Code] .....
Our problem is server could not generate alignMsg. But we can get it on local deployed project.

Generate 100 Numbers Using Arrays - Sort Even Numbers Into Separate Array And Display Both
Apr 24, 2014I've just written a program that generates 100 numbers that range from 0 ~ 25 using arrays, the program calls another method that sorts the even numbers into a separate array and returns the array. I need it to display both arrays, however, when I run my program, the numbers of both arrays are mixed together, and I'm not sure how to separate them.

Print 2 Lists - 20 Random Numbers And Another List Without Duplicate Numbers
Feb 1, 2015I'm trying to make a program that generates 20 random integers between 1 and 20 and then prints the list of random numbers to the screen. After that, I want to print a different list to screen with the same numbers from the first list only skipping any number that has been already printed to the screen. So two lists are printed to the screen. The first one has 20 random numbers. The second one has those same 20 numbers but only prints the numbers in the first list that aren't duplicated. So if m
y list of 20 random integers contains three 2s and two 14s, only one 14 and one 2 is printed to the second list. Currently, my code generates 20 numbers from 1 to 20 and stores those numbers in an array but I don't know how to print solve the second part of my problem. I don't know how to print the s different list only without duplicate numbers. As a result, my output is nothing because it doesn't print any number from the first list as oppose to skipping only duplicate one.
public void randomNum(){
System.out.println("Twenty random integers: ");
int max = 20; // max value for range
int min = 1; // min value for range
Random rand = new Random();
int[] all = new int[20];

ID Numbers Are All 0
Jun 4, 2014I don't know what I did to screw this up, but I had this code working to increment each employee ID by one every time a new employee was added. I tried to move the whole employeeID and newEmployeeID elements out of the constructor because everyone keeps telling me how bad it is to have those in the constructor. However, now, every time I add an employee, their ID number turns out to be 0. I have two other aspects of this project that are due soon, and if I can't fix this part, I won't be able to move forward to the other parts (which I am also stuck on at this point). The codes that are being used are as follows:

How To Add Two Numbers Using RMI
Apr 3, 2014how to add two numbers using RMI..This very simple example is taken from Chapter 24 of "Java 2: The Complete Reference" by P.Naughton and H.Schildt.The example is overly simplified but it still illustrates the basic steps in creating an RMI distributed program.
This example provides step-by-step directions for building a client/server application by using RMI. The server receives a request from a client, processes it, and returns a result. In this example, the request specifies two numbers, the server adds these together and returns the sum.(Of course, this program is intended only to illustrate the basic RMI mechanism.)The next subsections provide main steps in writing an RMI program
Define an interface that declares remote methods.The first file AddServerIntf.java defines the remote interface: it includes one method that accepts two double arguemnts and returns their sum. All remote interfaces must extend the interface Remote, that defines no methods: its purpose is simply to indicate that an interface uses remote methods.All remote methods should throw a RemoteException
import java.rmi.*;
public interface AddServerIntf extends Remote {
double add(double d1, double d2) throws RemoteException;
}
Implement the remote interface and the server
The second source file AddServerImpl.java implements the remote interface:
import java.rmi.*;
import java.rmi.server.*;
public class AddServerImpl extends UnicastRemoteObject
implements AddServerIntf {
public AddServerImpl() throws RemoteException {
}
public double add(double d1, double d2) throws RemoteException {
return d1 + d2;
}
}
All remote objects must extend UnicastRemoteObject which provide the functionaly that is needed to make objects available from remote machines. The third source file AddServer.java contains the main program for the server machine. Its primary function is to update the RMI registry on that machine. This is done by using the rebind() method of the Naming class (it is in java.rmi API). That method associates a name with an object reference.
import java.net.*;
import java.rmi.*;
public class AddServer {
public static void main(String args[]) {
try {
AddServerImpl addServerImpl = new AddServerImpl();
[code]....
Develop a client (an application or an applet) that uses the remote interface..The fourth source file AddClient.java implements the client side of this distributed application. This program requires 3 command line arguments: the IP address or name of the remote server, and two numbers that are to be summed.
The application forms an URL string using the rmi protocol, the first command line argument and the name "AddServer" that is used by naming registry of the server. The the program calls the method lookup() of the Naming class to find a reference to a remote object. All remote method invocations can then be directed to this object.The client program illustrates the remote call by using the method add(d1,d2) that will be invoked on the remote server machine from the local client machine where the client runs.
import java.rmi.*;
public class AddClient {
public static void main(String args[]) {
try {
String addServerURL = "rmi://" + args[0] + "/AddServer";
AddServerIntf addServerIntf =
[code]...
If you do not have an Internet connection, you can run all programs of this example on your local machine (both server and client). In this case, you can run
java AddClient 127.0.0.1 567 999
to use the "loop back" address (127.0.0.1) for the local machine. This will allow you to test the entire RMI mechanism without actually having to install the server on a remote computer.

Sum Of Numbers Between Two Integers
Nov 19, 2014I was trying to get sum of numbers between two given integer and managed to do it.
public int sum(int a, int b) {
int sum=0;
while(a <= b) {
sum+=a;
a++;
}
return sum;
}
in here; when I enter the values i.e 2 and 5, it calculates 2+3+4+5 and gives me the result 14.
my question is, how could I exclude a and b in this calculation ( in this case exclude 2 and 5 and return 3+4 )
Bonus question ; how could I only calculate the odd (or even) numbers between those integers?
