This is the code that I need to do without using the Joptionpane:
An Internet service provider has three different subscription packages for its customers:
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 unlimited access is provided.
Write a program that calculates a customer's monthly bill. It should ask the user to enter the letter of the package the customer has purchased (A, B, or C) and the number of hours that were used. It should then display the total charges.
This is what I have so far : Cannot use Joptionpaneshowinputdialog
/* A demonstration of how to use Decision Structures
import java.util.Scanner;
/** This program demonstrates a switch statement. */
public static void main(String[] args) { char packageLetter; int hoursUsed;
I am making a messenger app using mobile nation, the authentication widget is blocked because im not premium. I have set a text box that says username and password then a login and register button, the register button opens a url to a register page on a xxamp server i have. I made the site with wordpress, so in the mysql database it has wp_users. So when they press the login button id like it to select the username and password entered and run the java script to send that information to the xampp server to authenticate.
i have build an login form with which a user can login to see next form ,login form is working perfectly but whenever a user enters a wrong userid and clicks on login then nothing happens,i want that there a popup will be called and say wrong userid...
However when a user enters correct userid and wrong password then the popup is working but not when the user id itself wrong...
I moved some static html pages I was hosting from apache into tomcat. (no point in running two servers) This works as expected, but I'm having trouble with the authentication part. In apache the authentication was handled by htaccess. I tried various tutorials on the web about configuring basic authentication in tomcat using WEB-INF/web.xml in tomcat, but I'm not sure this approach applies to static html pages. Using basic authentication for static html in tomcat?
I'm building a JavaEE 7 web app and I want to add user authentication. Although I haven't found a complete guide, via the resources I've gathered I think I'm quite close. I can't make it work though. In all honesty I don't understand ALL of the code yet, I'm using it though because it's supposed to work, it's from JavaEE 7 Recipes book.
I've created my database, set up the JDBC realm in GlassFish, added the persistence unit, created the entity classes, the backing bean, the ejb, called the EL expressions...
When I'm supposed to login it throws a "loginBean.username is unreachable" or something. I don't understand why, the inputText's value is supposed to go straight to the backing bean right?
I'm trying to build a SSL mutual authenticating private server. I'm not sure what keystores, truststores, or certificates I need to accomplish this. I made keystores for both programs using:
I am writing a Twitter app, and I am encountering an error whenever I attempt to find the user's name from a screen name. I get the following error:
04-10 21:43:57.402: W/System.err(9326): No authentication challenges found
Which means that somehow, I'm not logged in. However, I am able to post, get the timeline statuses and even get the User of each status. I simply cannot do this:

I know this is a very vague description but I can provide you with all the code you may want, it's simply I cannot think of anything to do right now since I'm not familiar with the methodology yet...
For my job I would to develop a Java application which downloads some data from a webpage and then process them.
The problem is that I have to authenticate to a proxy server to connect to the internet. As I browsed on the net, there is a possible way for implementation.
Sometimes it works fine, but usually I get the following exception:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required" at sun.net.www.protocol.http.HttpURLConnection.doTunneling(HttpURLConnection.java:2083) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:183) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1511) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1439) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)
I don't understand what's the problem and why it's not persistent.
i am trying to access an https request on a server and authenticating it after passing on username and passwork. I have even set up the proxy of the employer to get the request back as a zipped folder.
I always get an error on: " InputStream reader = con.getInputStream();"
Can be a proxy setting issue too but I am not sure why it should be.
Is there a way to create a secure channel in java to connect to https or by any way the below code could be modified to connect it to the server?
Code is as below:
import java.net.*; import java.net.Proxy.Type; import java.io.*; import javax.net.ssl.HttpsURLConnection; import com.sun.org.apache.xerces.internal.impl.dv.util.Ba se64; public class DownloadFile {
I am making a program, where the user answers 3 questions and then I add the number of correct answers in to the (int) numberofcorrect variable, then I want to print the results, and no matter how many correct, the program executes first the correct if statement, then the else statement.
Eg: I have 2 correct it will print:
"Grade B, 2 of 3 "
"You failed the test"
Why does it do that? How can I change my code so the else statement dosent print if one of the if statments is allready printed?I want to know how to not execute the else statement, if one of the if statements have allready been executed.Below is my current code for this problem:
if (numberofcorrect == 3){ System.out.println("Grade A, full score");} if (numberofcorrect == 2){ System.out.println("Grade B, 2 of 3 ");} if (numberofcorrect ==1) { System.out.println("Grade C, 1 of 3");} else { System.out.println("You failed the test"); }
I want to execute my jsp code to compare two dates after every 10 seconds if user enter date and current sys date are equal it will send the mail to the user automatically. Below is my jsp code
this if condition i want to check the date after every 10 seconds and when two dates are equal it will send the mail using below mail code
if(ExpcReDt.compareTo(dateStr)>0) { out.println("Expected return date is greater than current date"); } else if(ExpcReDt.compareTo(dateStr)==0)
//Main method public static void main(String args[])throws IOException{ boolean runProgram = true; Scanner keyboard = new Scanner(System.in); //runs program while runProgram is true while (runProgram){
public class Main { private static void foo(Integer a) { System.out.println("Integer"); } private static void foo(long a) { System.out.println("long");
[Code] ....
This code prints long. Why is that? How did compiler decided that it likes long version of foo() method the most. If I had to guess I'd pick int... or possibly Integer as they are most similiar to what was passed. But why long?
I am unable to run this java mail code, whats the error!!
public class Class1 { final String senderEmailID = "from@gmail.com"; final String senderPassword = "password"; final String emailSMTPserver = "smtp.gmail.com"; final String emailServerPort = "465"; String receiverEmailID = null;
[Code] ...
I get an error as this

I want to execute and use the Win7 Speech Recognition with Java. How can I open it?
I tried to open it with "Runtime.getRuntime().exec(" ");" but I couldn't find a command to open it. How can I use the speech recognition once I opened it with commands in Java?
Question : How to execute batch file & .exe file using jsp servlet?I am giving input for blast in the FASTA format. After that i wants to make the sequence.FASTA file in my project folder. And I wants to execute batch file with parameters as blastp.exe file, sequence. FASTA file, database files, output file.
There is no problem in the file creation of sequence.FASTA
ERROR IN: the batch file is not execute, So the I am not able to get the output file for display.
ERROR is : java.io.FileNotFoundException: D:vaibhav_workspace.metadata.pluginsorg.eclipse.wst.server.core mp4wtpwebapps oxin-dataoutputprotein.txt (The system cannot find the file specified)
Technologies Used :JSP,Servlet,Process-builder
I have the following code as :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out=response.getWriter(); String values=request.getParameter("t1"); ServletContext servletContext = request.getSession().getServletContext(); servletContext = request.getSession().getServletContext(); String path="//sequence.FASTA"; /*file is created in getRealPath()*/
There are multiple .CSV files (each file has multiple rows and columns). I need to fetch data from all the files and find MEDIAN of the values for each column and do further calculations. Suppose there are 3 files, i need to find the MEDIAN of column 1 in file1, MEDIAN of column 1 in file2, MEDIAN of column 1 in file3. Below code just fetch data from one file.
I have few queries regarding compiling v/s execution of a java program. Suppose I have a Main Class which is referring to class Test which is present in JarA. Now, at compile time, this jar JarA must be present in classpath/buildpath. So, what actually is the action performed by the compiler by referring to this jar?
Now, at runtime also, this jar should be present to execute the Main class. Is this correct? If yes, then what is the action performed by JRE when it refers to this class at runtime? WOn't all the dependencies be resolved at compile time only?
