What is in each iteration:this.orikaFacade.map(a1, a2);
or
a2 = (A) this.jmapper2.getDestination(a1);
I know, that Orika and Jmapper are great libraries from Google and they use reflection in a different way than for example Dozer, which is much slower, they se reflection to generete code somehow..
I have 3 questions:
1) How they work - when the code is generated, during maven build, in runtime - everytime when I create mapper in code? Are they change class code byte dynamically?
2) Why there is this speed difference that I noticed?
3) Which library would you choose and why? Both have the same capabilities? Why both come from Google? Why Google didnt develop Orika and created Jmapper instead?
When casting a char which is read from a file to an int, can i assume that the mapping used will be ASCII? I've learned that unicode uses ASCII mappings for the characters that overlap.
Are there any other possibilities for int values of one character? I still have trouble understanding character encodings.
I am writing a program where I need to split an array of full names into First names and Surnames, using mapping. However, I am struggling how to split it up... and my First Names and Surnames list are both just displaying the full name.
public static void main(String[] args) { String[] names; names = new String[8]; Scanner s = new Scanner(System.in); for (int i = 0; i < names.length; i++) { System.out.println("Enter full student name:");
And this works fine: URL....The war file is deployed under the context root /bankconnect/ I want to make a servlet mapping, before the context root "i still want the context root bankconnect". URL....
I'm working on a project and I'm just about to implement different stages (menus etc). The program is opened in an intro stage that just renders a text (slick, Unicode font) looking like this:
After switching to a different stage hat uses shadow mapping and then back to the intro stage it looks like this:
I'm looking for a working example of shadow mapping with java code using shaders. There are so many c++ or c tutorials out there but i haven't managed to rewrite them since I'm too bad in c/c++. I've been trying to implement this a long time but can't get the hang of it. Any example out there? Preferably as sstripped down as possible except for the shadow mapping.
We need to process (read and parse) big xml files (500 Mo to 1 or 2 Go). What's the best framework or Java library to use for this requirement ? Then what's a good OXM (in this case xml to object mapping) solution for this kind of file ?
I am attempting to test a TCP Client and Server for an assignment I am doing in class. The goal here is to "test your client and Server applications by transferring (i) a file having 10,000+ lines (see supplied big-file1.txt having 12000+ lines), (ii) a file having 20,000+ lines (you may create one of your own from big-file1.txt, or obtain a large size file from the Google website at [URL] ...). Then, compute and display the total transfer time of the files at both of the sides separately (your choice in millisecond/second)."
I have created the TCPClient and TCPServer java classes, ran the server first and then the client, and using mathematical formulas to calculate the transfer time. Trouble is, I'm having trouble testing the client and server in the file area and not the area where I had to input a line, let the server print it, and then have the client eliminate the articles from the line. I need testing the file. Here is my code so far:
TCPClient:
package tcpclient; import java.io.*; import java.net.*; public class TCPClient { public static void main(String[] args) throws IOException{ // TODO Auto-generated method stub String sentence;
[code] ....
How to fix the code so that the time in seconds does not output as 60 for both files and that the files go through the exchange?
I wrote a class for encapsulating coins and I was to do a boolean statement but when I test the statement the results are not showing.Here is the code for my coin class coins.java
package project_3; /** * * @author user a */ public class Coins { private double pennies; private double nickles ; private double dimes ; private double quarters ; private int dollars ;
how to execute a particular class. I've created a Kinematics class that will execute and calculate all the functions pertaining to kinematic equations. In the main class, I will have the user provide the data in JTextField. Now I need to test which JTextfields (variables) were left empty. I plan to use a number of if/else statements :
if(distanceI != null && distanceF != null)
The problem with this is that these variables are double and therefore cannot be tested as null. I read a few things about Double but I really don't see how I'm supposed convert each double variable to Double, is that even possible?
public class Kinematics { double distanceI, distanceF, velocityI, velocityF, velocityAverage, acceleration; public Kinematics(){ //v2 = v1 + a*dt if(distanceI != null && distanceF != null){
I have been designing a music collection application that runs from a database. I now need to develop a junit test to test the application but I am not sure if Junit has anything to work with testing databases. I have been googling on the internet but most of the search results do not really give any good examples that I can easily follow and adapt to my application. I am using only one table and I would like to test INSERT, UPDATE and DELETE actions and I would also like to test a successful connection.
I once found one tutorial which I cannot find any more that had something that retrieves all the data in the database and stores it in a CSV file and the loops through the CSV file to check or update information.
We generally use [URL] ..... for running web applications.
What I want is to access my web app using something like this: [URL] ....
How to achieve this? Actually what i want to ask is that how URL like WWW.example.com is mapped to web applications? Assuming that i am using tomcat server.
How do you test the events within an inner class using JUnit
// File: : events/SomePanel.java // Purpose: Show use of named inner class listener.
import javax.swing.*; import java.awt.event.*; class SomePanel extends JPanel { private JButton myGreetingButton = new JButton("Hello"); private JTextField myGreetingField = new JTextField(20);
[Code] .....
Code extract taken from: Java: Inner-class Listeners
Taking the above example, do I need to use myGreetingButton.doClick to trigger this event to test the respective variables/values being used ? Also the Actionlistener inner classes is private so doubt I can access this from JUnit Test class.
I've been beavering away with Java for a few months. But as with all languages the String implementation looks designed to trip up even experienced programmers.
My current development gets data from various sources outside my control. When I get a string I want to test if it is empty/null/or whatever. Simple enough one thinks.
But if you search the internet you see everone seems to have a slightly different approach. So what is the best way of determining that a string is not useful to you?
I've had success with this
if(string == null || string.length() == 0)
But I've seen people using methods - not necessarily of String (e.g equals, empty) and regular expressions.
What is the best approach to this considering coding efficiency and/or processing efficiency (accepting you'd have to be processing a lot of strings for the latter to be an issue).
I have a bean that represents data been collected from a form on a jsp page. Currently I would like to validate my fields and write some test cases for them. As you can see from my test case example I test a string in the hope that it fails because it contains only one letter. My problem is my unit test is passing. The reason this is from what I can tell is that at runtime it fails when I try to persist my object using my entity manager. During my unit test I just I don’t call my entity manager I just try and set the field.
What I thought would happen was that when I use my bean fields set method the annotations would be checked and fail at that point. Hence why I expected my unit test in this case to fail.
What I would like to know is
1.Are annotations specifically designed to validate when I persist my object and am I using them incorrectly at this point?
2.Is this the best method to use to validate fields, is there a better way, should I write my own code to validate for me when I set my value?
a. Should I throw an exception from the set method of each bean field?
Unit Test:
@Test public void testName(){ Human h=new Human(); try { h.setFname("a"); } catch (Exception e) { // TODO Auto-generated catch block fail("failed"); e.printStackTrace();
My issue is that when I run the code if I enter anything but 1, 2, or 3 the code breaks. I have spent hours trying to find the error. here is my code
import java.util.Scanner; public class Tester { public static void main(String[] args) { /** * constructor * pre: none * post: inherit values of other classes */ Car Car = new Car(); //inherits the properties of the Car class Truck Truck = new Truck(); //inherits the properties of the Truck class
When I map my servlet to the ROOT of the site, the javascript, CSS and image files are not served. The conversation between the server and browser shows the files are being sent, but they are not rendered in the browser. This happens in both Firefox and Chrome.
If I change the mapping to anything other than the root, such as /x/, everything works as it should.
I have code for precision and recall testing for search engines. I am trying to run it in Newbeans 8.0, but I am getting the common error in UnsupportedOperationException
I have tried making files and directories as the given in the code file. I am attaching the two files here.
I need to build an application that can preform measurements. So I have a measuring device that can be connected through USB (with a rs232 converter aka VCP).The manufacturer provided me with two libraries:
C++ : a library (.lib) file and a header (.h) file VB6 : a DLL (.dll) file and a list (.txt) with all the available functions
And also some demo code. Can't get the C++ code running with my Borland C++ 5.5 compiler but the VB6 code is working.What can I use to integrate into my java code.
I've been trying this for hours but it's not working. I'm trying to add the sea glass look and feel library to my project but I still get the error:
Exception in thread "main" java.lang.NoClassDefFoundError: List (wrong name: list)
What should I do? I've added the library to "project settings >Required Libraries" and did not forget to check the box. I've also imported the L&F so it can't be that.
I'm researching the viability of a project. One of the requirements is that a "play slip" will be used to read input. I've searched for open source Java libraries that utilize OMR's (optical mark reader) but to no avail. I have located a C library that fulfills the task- is there a way in Java to access/use non-native language libraries?
