I have written a program to enter a name in a text box of an html file, get the name in a Servlet, search for the name in the database and inform the user whether or not the name is in the database via an applet. I'm trying to get the information from the applet to display in a colored oval, green w/white font if the name is in the database and red w/black font if the name is not in the database. I can get the information to display just not in the colored ovals and text that I want, I am including only the applet code, not the HTML or Servlet.
import java.applet.*;
import java.awt.Color;
import java.awt.Graphics;
import java.sql.*;
public class MyApplet extends Applet {
public void paint(Graphics page){

"In this assignment you will use an applet to display images of playing cards. The applet should load a deck of 52 playing card images from the "images" folder that you downloaded. The applet should shuffle the deck (use a random number generator) and display the first 10 cards of the shuffled deck. Display the cards in two rows of five cards each."
That is my goal for this assignment. I've got my code compiling and I will post it below and I've got an html page but when I try to open it I get an error
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Image;
import java.util.Random;
public class Assignment12 extends Applet {
Image card1;
Image card2;

I am trying to finish this servlet that adds a new course to my courses display. im using a check box so the user can pick what the prerequisite are for the new course they want to add. so if they check cs201 , it will add cs201 as a prerequisite for that new course.
for some reason my checkbox will only add the first checkbox that is clicked. like if i add a subject , and click the check boxs for cs203 , cs202, and cs201. it will only grab cs201 and add it to my course display. it wont grab all 3. how can i grab the other info thats checked?
package cs320Homework1.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;

out.println("</select>");
out.println("<link rel='stylesheet' type='text/css' href='css/table.css'/>");
out.println("<input type='text' id='searchText'/>");
out.println("<input type='hidden' id='hide' value='" + selected + "'/>");
out.println("<input type='button' value='Search' onclick='getData()'/>");

What I want is ..on selecting heading check box...all the below check box should get selected....and clicking on delete button which i will create later on...i want multiple rows to be deleted from database....

I'm guessing the vehicle checklist is for making your car? So like for the tires there would be 3 options and you check which one you want?
View Replies View Relatedmy code is ignoring the checkbox option when Iterating in loop like this:
<tbody>
<c:forEach items="${users}" var="user">
<tr>
<td><input type="checkbox" name="deleteFromList" value="${user.id}"/><input type="submit" value="Delete" name="action" ></td>
</tr>
</c:forEach>
</tbody>
The output of value="${user.id}" is retrieved from a DB, it looks like this:
Id Nombre usuario Email Fecha de registro Acción
1 isaac2 @2 1986-01-01 *Delete(input) *Here there is check box
2 isaac3 @3 1988-01-01 *Delete(input) *Here there is check box
Then depending of which check box I selected then the row by the side should be selected by id and deleted.But what happens is that doesnt matter which check box I select, always the first row is deleted. I understand that at the first iteration of the loop it just take the first id, it doest attach the id I have choosen to the row it belongs to
I am working on a web application for store file maintenance. Need to add a new Check Box "Activate Selected Menu items" on the page.
what code i should write to add a Check Box.
I would like to defined a TableView with a column containing a CheckBox.
This can be done with an instruction like this : myColum.setCellFactory(CheckBoxTableCell.forTableColumn(myColumn);
The problem is how to specify that the displayed CheckBox is an indeterminate one ?
I created two CheckBox in 2 tableColumn and I want to listen theire change. I tried
col_orien.setOnEditCommit
But it doesn't work (col_orien is the name of the tablecolumn that contain the check box)
Here is my code :
col_orien.setOnEditCommit(new EventHandler<CellEditEvent<Information,Boolean>>() {
@Override
public void handle(CellEditEvent<Information, Boolean> event) {
System.out.println("Edit commit");
}
});

I am working in jsf application, in that one requirement is present. If we click "Take picture" button using webcam from web browser, image has to be captured and displayed in the screen. Finally by clicking save button picture has to be stored either in Database or in File Folder.
View Replies View RelatedI am trying to learn Java and while i was playing a bit with the basic knowledge that i have i encountered a problem. When i run the program, the lines and the picture appear in two separate windows when i compile the program. how can i make them appear in the same? The code is this:
public class Game

I've been trying to post background picture for a long time in java. I've just finished writing breakout game and I want it to be more special and full of interesting things. I want to upload picture in java. I write
GImage image= new GImage("LEONARDO.JPG");
image.setSize(50,50)
add(image,200,400)
The size of the whole screen is 400,600.
I'm stuck with a problem. The code below generates a coloured image.
//Setting the size of the graphics window
final int WINDOW_DIMENSION = 200;
final int SIZE_FACTOR = 3;
EasyGraphics generate = new EasyGraphics(WINDOW_DIMENSION*SIZE_FACTOR,WINDOW_DIMENSION*SIZE_FACTOR);
//Constructing the arrays
char[][] firstArray = new char[WINDOW_DIMENSION][WINDOW_DIMENSION];
char[] secondArray = scan.toCharArray();
[Code] ...
What I would like to do is generate a picture which is mostly white but the colour boundaries of the original picture are in black. I tried using the code below but it doesn't produce what I wanted.
for (int a = 1; a < WINDOW_DIMENSION; a++) {
for (int b = 1; b < WINDOW_DIMENSION; b++) {
generate.setColor(0,0,0);
if(firstArray[a][b]!=firstArray[a-1][b] || firstArray[a][b]!=firstArray[a][b-1])
generate.setColor(255,255,255);
generate.plot(a,b);
}
}
PaintWindow pw = new PaintWindow();
Random rand = new Random();
ImageIcon image = new ImageIcon("C:/Users/Ghostkilla/Desktop/gubbe.jpg");
setWidth(pw.getBackgroundWidth());
int height = pw.getBackgroundHeight();

If you run this code it will move a picture from right to left and hit the left wall and then go to right again leaving the window (It stops there). I want to make so it hits left and then right wall continuously till someones close the window. So basically I am using a for loop to make it go left right all the time.
How to make so the picture moves from bottomleftcorner to toprightcorner diagonally without leaving the window.
I'm trying to save a picture from byte arrays using RandomAccessFile. The file appears but doesn't open (like its corrupted).
I'm using the bittorent protocol which gives a SHA-1 hash that I compare all the bytes with to verify the data. All the bytes pass the hash check and all the hashes are checked. So I'm pretty sure I'm getting all the bytes correctly.
Is there anything I can do that could tell what's going wrong?
public RUBTClient(final TorrentInfo2 tInfo, final String outFileName) {
...
this.outFileName = outFileName;
File destined = new File(outFileName);
try {
destined_file = new RandomAccessFile(destined, "rw");
destined_file.setLength(tInfo.file_length);
} catch (FileNotFoundException e1) {

I have to write a program that will read a picture and then print out the number of blocks inside it.
I have to read the picture as a binary matrix of the size r - c (number of rows times number of columns). The blocks are groups of one or more adjacent elements with the value 1.
- Blocks are built exclusively of elements with value 1
- Each element with value 1 is a part of some block
- Adjacent elements with value 1 belong to the same molecule.
We only take into account the horizontal and vertical adjacency but not diagonal.
INPUT:
In the first line of the input we have the integers r and c, separated with one space.
Then we have the r lines, where each contains s 0's and 1's.
The numbers inside the individual lines are NOT separated by spaces.
The OUTPUT only print the number of blocks in the picture.
Example:
INPUT:
7 5
01000
00010
00000
10000
01000
00001
00100
OUTPUT:
6
THIS IS WHAT I CAME UP SO FAR:
import java.util.Scanner;
class Blocks{
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
char ch[][];
int rowNum=sc.nextInt();
int columnNum=sc.nextInt();

I want to make a simple game and learn java by experimenting with it.I don't know how to increase a value by clicking it.I know how to make my objects move in my small game with mouse or keys, but I also got a score var that I want to increase per click. I can increase it over time, but after 2 hours of trying I couldn't progress any further.This is the piece of code I used, I imported the class, got getters n setters and all of that...
if(e.getButton() == MouseEvent.BUTTON3) hud.setScore(hud.getScore() + 555);
Whenever I click I get an error, if I remember right "NullPointerException" is when something is missing I'm probably not targeting the value correctly...
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

I am writing a script for a program, now I am very new to Java. So, issue I am having is the program keeps clicking on the MM continuously. I just want it to click each spot 1 time.
Here is my code :

Tile Portal = new Tile(2681, 2591);
Tile To = new Tile(2667, 2601);

I've been programming for a while, but I never made executables... just ran it from the compiler. Now, however, I really want to have an icon for one of my programs that would be conveniently located and clickable. So, I made a jar file, both in Eclipse and BlueJ. When I run this file in command line, it works fine (with "java -jar ..."). In case of Eclipse, this worked with both "jar" and "Executable jar" options. However, when I double click the icon, nothing happens. First I was getting "can't find main class" error, but that was an easy fix with the manifest file. But now, nothing seems to happen at all. Could this be because the program is supposed to run in the command line or whatever the compiler offers and there is nothing to force the computer to open one of those windows?
View Replies View Relatedas there is a button on the website, that I need to click, but it returns a number using javascript that will access the page. Without that number, accessing the page won't work. Therefore, either I need to click the button, or return that data when I access the url. Here is the line in the html.
