Jul 20, 2014i am running into a problem with my program. It seems my BasicCalc class is running fine but having some difficulties with displaying it with a system.out. println instead of the system.out.printf. When i do try and change it i get this result:
C:myJava>javac BasicCalc.java
C:myJava>javac Calculate.java
Calculate.java:42: error: no suitable method found for println(String,double,char,double,double)

How To Develop Student Information Page On Web

Servlets :: Front End JSP Conforming To SQL
Sep 24, 2014A data entry form is on the front end. This allows one to enter say emails, addresses, etc. It utilizes a jsp, jstl, servlets, and beans. The backend sql has say a size of 50 for email. If more than 50 char are entered on the form, w/o any intervention, a truncation error is thrown. A static class was set up to hold the input element names and max sizes. It seems to work well keeping all in check, names and sizes on form, names in servlets, size of sql.
servlet
req.setAttribute(elementname, elementobject)
jsp
maxlength="${date.maxLength}"
name="${date.inputName}" //setattribute objects
servlet
.getInputElement("date").getInputName() //static map...shared with above objects
Is there any other system of keeping everything in sync. I am building it all, but I was wondering how this is parsed out if there are separate sql, middle-tier, and front-end developer? It seems better just to have good documentation that would be shared between the different implementers.

View Replies View RelatedImage Won't Appear In Front Of Other Graphic Objects
Feb 3, 2015For the assignment, we are supposed to make a checkerboard with alternating colors, then put images on top of certain spaces to act like "pieces." I did the checkerboard, but whenever I go to try and put an image the checkerboard, it doesn't appear! I put the image in the same directory as my other code as well. I did some experimenting and discovered that the image is appearing, but behind the checkerboard.
Here is the code:
import java.awt.*;
import javax.swing.*;
public class CheckerBoard extends JApplet{
public void paint(Graphics g){
super.paint(g);
Image img1= getImage(getCodeBase(),"arrow1_nw.png");
g.drawImage(img1,500,500,this);

Move All Of Number 7 To Front Of Array
Jan 24, 2015I'm using Dr.Java and doing a numbershifter lab. I have to create a random array of number from 1-10. Then move all of the 7s to the front of the array. The order of the other numbers is not important as long as all numbers follow the group of Lucky 7s. Files needed Numbershifter.java and numbershifterrunner.java. All data is random.I have done the following:
public class NumberShifter
{
public static int[]makeLucky7Array( int size)
{
int [] newRay = new int[size];
for( int i=0;i<newRay.length; i++)
{
newRay[i] = (int)Math.round(Math.random()*10+1);
[code]....
It's adding to many 7s in the front of the array.
Swing/AWT/SWT :: Graphical Front End For A Poker Game?
Oct 19, 2014basically I'm a good way through developing a Poker game which I've been developing just for fun(!?) and also to improve my skills, which it has done substantially. The logic involved with some of the hand comparisons and the evaluations of the winner is pretty complex.
Nonetheless, once I've finished the threaded timer to control the regulation of rising blind levels, and the betting mechanics for the Computer players I'll be looking to start creating the front end and this is where I'm a little confused.
Obviously for what I want, neither swing or AWT would be sufficient, so I guess the gap in my knowledge is how to integrate my back end code with a web front end. Is this possible? - What options exist for integration? just pure CSS / JS, or would Angular.js be viable? I'm looking to utilise some ready made images as graphics with maybe some minor animation effects.

Design And Implement GUI Front End For Computerized Version Of Battleship
Feb 21, 2014Code for implementing a simple computerised version of Battleships has been supplied. Examine the code ensuring that you understand it. The game is played against the computer.
A number of ships (default is 6) are place randomly on a 4 x 4 grid. A ship occupies one square only. The player then guesses the position of a ship. If he/she guesses correctly the ship is HIT and sinks. If the guess is incorrect the player loses a life. The default number of lives is 7. If the location has been guessed already, no lives are lost.
When the game starts, a 4 x 4 grid should be displayed.
The user should be allowed to enter/select a cell location. If the selected cell contains a ship, the ship will be destroyed. If not the player loses a life. The cell should display an appropriate picture, icon or message informing the user of its current state.
The number of lives and number of ships remaining should be displayed.
When the game ends an appropriate message should be shown informing the player whether he/she has won or lost. The positions of the ships should also be shown.
The purpose of this assignment is that students demonstrate an understanding of the Java Swing library and that he/she can navigate and use the API effectively.
Your finished GUI should be both user-friendly and aesthetically pleasing.
Ideally, the user should have the option to play another game, to quit or give up mid-game. You may also wish to include other options such as different levels of difficulty, etc.

View Replies View RelatedJavaFX 2.0 :: Creating Front-end Application That Uses Command Line Tools
Sep 8, 2014I'm creating UI's that run on top of backend tools that can run from seconds to days and output GB's of generated data (imagine running tar on the Google servers).
I understand how to execute my backed tools using a runtime process and how to interact with them, and running a simple text as a command line Java app works as expected. The issue occurs when I wrap the code in a JavaFX frount end UI try to update the UI elements in a reasonable manner. If I simply use System.out.println() as in the command line version, I see the output from my task. However, simply trying to put that same output into a TextArea using .appendText() doesn't update the TextArea until the background process completes.
I see all sorts of clippings relating to Task, CreateProcess, invokeLater, updateProgress, but none of them seem to solve their original posters' question (nor mine at this point).
Java EE SDK :: How To Access Remote Persistent Objects From Web Front Client
Apr 1, 2012I have a doubt about how to design a web application which has their persistent objects in a service layer in a remote server, i mean a business application. So, once we have a web application as a client of this remote business application, how those persistent objects should be mapped in web front?
Should I either pack all jpa annotated classes into the web front application or there is another neat way to do this?
I was intending in copy all persistent classes present in the remote business application into the web app package, i know it's not the best way to get what i need.
What is a more appropriate design for a web application which must get some objects from a remote business application and persist some other objects there?
