I am working on a project for a store. I need to accept the purchased items from the user and an automatic cash memo would be generated. Now I have an experience with building desktop applications before and have managed to build up the UI. Presently I am stuck in creating a template for the invoice/memo (whatever you may call it). I have the following requirements:
1) How do I create a good template for invoice/memo with the company logo ??? Do I have to rely on any third party software? Any detailed tutorial would be useful.
2) How do I convert that invoice/memo to a pdf file???
I have a Java application and it uses various Freemarker templates to created Web pages for a Web site. Here is a snippet of one of my Freemarker templates that will display the fee description, fee charge, and an add button. The fee has to do with charges that pertain to automobiles. When I click on the "Add" button, I will be taken to another Web page. How would I send the fee.description and the fee.charge to the other page when I click on the "Add" button?
I want to print data on invoice receipt size of 20.5 x 14 cm(hard copy). In which I try to put text at some absolute location. I tried iText first. In that I try to set page size by following code. here what is unite used in bracket of rectangle?
Document document = new Document(new Rectangle(552,377)); PdfWriter.getInstance(document, new FileOutputStream("report.pdf")); document.open(); ... ... ... document.close();
Second I tried Jasper report. In that I set page size to 20.5 x 14 cm. But how can I take value from my java application's textfield and put it in to some absolute location in iReport.As I know jasper report take value from database but how can I take value from java application's textfiled?
I am more familiar with iText. How can I print custom invoice using iText or Jasper Report.I am developing java application using netbeans.
I'm wondering if there's a way to build a template for managed beans which could be extended by a constructor instead of re-writing beans for each entity. I can do that quite easily for Dao objects by creating facades and using those facades to create Dao implementations for specific entities. Not sure if the same concept works for managed beans and haven't really come accross any searches.
I wrote the following but I'm not sure how to implement or even if the concept of generics and templating can be applied to managed beans in the same way it can be applied to Dao classes:
public class BeanTemplate<T> { private ListDataModel<T> listModel; @EJB private GenDao dao; private Class<T> entityClass;
[Code] .....
The above assumes there's only one method needed in the bean. I thought of extending like this:
public class EmployeeBean extends BeanTemplate<Employee> { public EmployeeBean() { super(Employee.class); }
// how can the methods be called??
Is the same concept for creating dao templates possible for managed beans?
In the test program, you will need to convert the Strings for quantity and price to numeric types. To do this, you could use the Integer.parseInt() method and the Double.parseDouble() methods. I'm not sure what he means by that. I attempted it in my program but I get these errors
Exception in thread "main" java.lang.Error: Unresolved compilation problems: number cannot be resolved to a variable description cannot be resolved to a variable quantity cannot be resolved to a variable price cannot be resolved to a variable Duplicate local variable quantity Duplicate local variable price Syntax error on token "myInvoice", delete this token The method getinvoiceAmount() is undefined for the type String
at InvoiceTest.main(InvoiceTest.java:7)
Code:
public class Invoice { private String number; //Instance variables private String description;//Instance variables private int quantity;//Instance variables private double price;//Instance variables
I'm making a small play in java in which you have a limited time to make as many moves as possible (with the aim of achieving a maximum score), like this: URL...
In the game panel I see the map on which you will perform the moves and a score indicator constantly updated. I have to add the indicator that shows me the passage of time (first 3 minutes), in digital format mm: ss. I thought I will be a useful thread called Countdown because I have to stop this counter if the user presses the pause button in the game. Then wanting to continue the game shall resume the countdown.
when I am programming let say in VB using Visual Studio, finally I build .exe file that can be run on all Windows by double click.For Java I am using Eclipse and to run those apps I am using run from Eclipse.How I can create a sort of "executable" for my Java app that I would be able to run it by file click on Windows or Linux?
I keep getting this error:- /opt/solr# java -v Unrecognized option: -v Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
How would you begin a program that schedules events? I've found codes that are similar like Calendars, but I need something that will still import the real day, month, year. But I want to have columns that show Room numbers, and rows that shows time slots. How to get started such as which GUI components to use, what packages to import, etc.?
Create a Java Application in NetBeans with the following two classes.
1. A Java class College o Use the following data fields: College Name College City Number of Tracks Number of Students Number of Faculty Number of Staff o Implement an empty constructor o Implement a full constructor o Implement Setters and Getters (Mutators and Accessors) o Implement SetAll() method with all data members as parameters
2. Another Java class called CollegeDemo with the main() method: o In the main(): o Read the values of the fields of 3 colleges from a text file and for each create a College object. Filename: colleges.txt IT Dubai 7 200 50 20 ENG Abudhabi 4 400 60 20 SCIENCE Sharjah 3 300 40 20 First with empty constructor then uses setters. Second with full constructor (no need to use setters). Last one with empty constructor and SetAll() setter. o Display the average number of students for all the 3 colleges. o Change the value of ‘Number of Students’ in the SCIENCE College to 500, and display the average number of students again.
here my code :
public class Demo { private String name ; private String city; private String cname ;
Since a few weeks i receive windows reports with the text: "Could not create the Java virtual machine". That were not disturbing, but now i would like to play a game that based on Java, but every time I would start it, the message come and the game do not start. The game called "Edna and Harvey: The Breakout" (German: Edna bricht aus) and is developed by a german game studio called "Daedalic entertainment".
(Using an Existing Class: Creating Objects and Calling Accessor and Mutator Methods)
I. The Assignment
This assignment is to write a "test" class (aka: a "driver" class or "client code") that uses the class Balloon.java, available on the class web page.
To use the Balloon class, download it and store it in the src folder of your NetBeans project. Make sure you save it as Balloon.java.
The best way to learn how to use the Balloon class or any other Java class, for that matter - is to consult the documentation, Balloon.html (online). You can also read the javadoc comments that appear just above the class declaration and above each method declaration, which explain what each method does, what the method's parameters are, and what value if any - is returned by the method. The html support pages are generated from these comments.
-Review declaring variables, creating objects, calling methods that return a value vs. void methods, and accessor and mutator methods before beginning. To receive credit for this assignment, you must not modify the Balloon class in any way!
II. Your BalloonTester Class
Your BalloonTester class will have only a single method "main" and will perform each of the following operations, in the exact order listed below. Each operation may be done in one or two statements. Make sure you follow directions faithfully, and note that once you have done step 3, you can copy and paste it to do steps 6, 9, and 12.
1.Create a Balloon object with a name of your own choosing and an altitude of 100 meters.
2.Create a second Balloon object with a name of your own choosing, and specify an initial altitude of -100 meters.
3.Call the accessor methods of the Balloon class to get the name and altitude of each Balloon object. Print the data, one object per line.
4.Make the object you created in step 1 ascend to an altitude of 250 meters.
5.Call the adjustAltitude method to increase the altitude of the object you created in step 2 by 150 meters.
6.Call the accessor methods of the Balloon class to get the name and altitude of each object. Print the data, one object per line.
7.Call the adjustAltitude method to decrease the altitude of the object you created in step 1 by 150 meters.
8.Make the object you created in step 2 descend to the same altitude as the other object. You may assume that the other object is at a lower altitude.
To get credit for step 8., the statement(s) you write must always work, regardless of the actual altitude of the second object. It cannot depend on you knowing the altitude of the second object, but must utilize the fact that the object knows its own altitude. In other words, if you use a literal in any way to set the altitude, it is not correct.
9.Call the accessor methods to get the name and altitude of each object. Print the data, one object per line.
10.Move the object you created in step 1 to an altitude that is four times its current altitude. As in step 8, the statement(s) you write must work for any altitude and may not depend on you figuring out the new altitude beforehand.
11.Attempt to move the object you created in step 2 to an altitude that is 150 meters below its current altitude.
12.Call the accessor methods to get the name and altitude of each object. Print the data, one object per line.
and this is the Balloon.java given:
// File: Balloon2.java // Modified Balloon class has overloaded constructors
/** * A class to represent a hot-air balloon. Balloon objects have a name and an altitude. */ public class Balloon2 { // instance variables private String name ; // name of the balloon private int altitude; // altitude (height) of balloon in meters
Create a java application that contains an array of 10 multiple-choice questions related to you favorite hobby. each question contains three answer choices. also create a parallel array that holds the correct answer to each question - A,B, or C. display each question and verify that the users enters only A,B, or C as the answere - if not, keep prompting the user until a valid response in entered. If the user responds to a question correctly, display "Correct!"; otherwise, display the correct answer is and the letter to the correct answer. After the user answer all the question, display the number of correct and incorrect answers.
I am wondering if there is an easy way to create a java exe(cutable) binary, by packing the JRE and ship it like a compiled C++ bin file? I know JAR is good but, I still prefer to create a standalone install - free exe, no matter if the user has or has not Java installed on her PC.
I have to create a dictionary in java using search trees. I have problems with the methods put() and remove(). Working properly, ie correctly adds a new element and eliminates correctly. But I should improve a few things.
As you can see from the interface, both methods must return an element of type V, that is:
- case put(): returns the previous value associated with key (or null if the key was not associated with any value) - case remove(): returns the value associated with the key (or null if the key was not present in the dictionary)
I do not understand how come my put method always returns null even though in reality I make him return node.getElement().
Instead, the remove() method does not know how to modify it to make sure it returns the value associated with the key. If I change the helper method return value in V (instead of Node<K, V>) method does not work anymore...
How can I then edit these two methods?
Class SearchTree: public class SearchTree<K extends Comparable, V> implements Dictionary<K, V> { public int size; public Node<K, V> root; public SearchTree() { root = null; size = 0;
For a shool assignment i have to create a java irc client. which responds to commands. the !SENDMSG command has two parameters !SENDMSG <username> <the message>.
i can get the username and the message seperated, but i would like to create a check in case someone gives a bad command like: !SENDMSG" " <-- note te extra spaces, or if someone gives only 1 parameter.
