Swing Applet - How To Display Data
Oct 28, 2014
I'm doing a project in which I must display prices of computer accessories in a Scroll Pane viewer. The if statements are all checkboxes. I am completely lost with how to print to the viewer if a checkbox is selected. Furthermore, I am also lost with how to add up all of the checkboxes.
private void USBCheckActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
double area = 0;
double computerprice = 500.0;
if (printerCheck.isSelected()){
double printer = 100.0;
[Code]...

I was trying to run an sql query to display onto my jtable. However, i got this as a result:
oracle.sql.CLOB@11876a2
When I run the same SQL query on Toad i get the field hugeclob and one is then able to see whats inside the field. I want to basically either have a hugeclob on my jtable or perhaps to display on a textarea the data

I have a tree-based data structure that looks somewhat like this:image1.png..Every tree always has a height of no more then 3, and each of these classes has a very specific use, generalization is not possible between them.Now, I want to display my data structure with a JTree in a Swing application. A JTree needs a TreeModel and so I created a custom TreeModel for my classes, it looks like this:
public class CustomTreeModel implements TreeModel {
private Root root;
public Object getRoot() {
return root;
[code]....
But then I would introduce this interface to my Model classes just for the purpose of writing the View. So my data model has to be altered to make the View work, this sounds completely against MVC to me and also like something I dont really like.On the other hand, the CustomTreeModel would be much simpler, easier to understand, easier to maintain and just in general more pleasing to the eye.Should I change my Model to improve the View? Is instanceof okay to be used in View classes?

So I'm trying to make an applet that displays images of playing cards. The applet should load a deck of 52 playing card images (the folder is called "images"). The applet should shuffle the deck (using a random number generator) and display the first 10 cards of the shuffled deck. I then have to display the cards in two rows of five cards each.
With this code I have about 100 errors and I'm not sure what I'm doing wrong:
import java.util.Random;
import java.awt.Image;
import java.applet.Applet;
import java.awt.Graphics;
public class unit12 extends Applet
{
Image card1, card2, card3, card4, card5, card6, card7, card8, card9, card10;
[Code] ....

I coded up a simple applet and some html with an applet tag and it tested out OK using the applet viewer. But it doesn't do anything (except draw a grey empty box 100x200) when executed from the application server. For the applicaton server test, I put the applet tag in the HTML Body of the JSP page i.e.
<applet code=CatApplet.class height=100 width=200> </applet>
The applet class file is in the same directory as the JSP page. The source for it is:
import java.awt.*;import java.awt.event.*;import javax.swing.*;import java.io.*;import java.net.*;
import java.util.Date;public class CatApplet extends JApplet{public void init (){setBackground(Color.green);
resize (250,100);}public void paint (Graphics g){g.drawString ("lets get some cat gui going", 35, 15);}}
Why won't my applet run when the applet tags are in the JSP page?

I want to embed an existing JAVA applet in to my swing application which is a standalone application. The applet is used in some other application which is not developed by me or my company. The application is open source application (So I have the source code). The entire existing application is basically one of the parts of my new application.

I have 3 csv files as follows -
author file columns - emailID | firstname | lastname
books file columns - title | isbn | author_email | description
magazine file Columns - title | isbn | author_email | releasedate
I need to display -
1) Based on the ISBN display all books and magazines
2) All books and magazines by an author
3) All books and magazines by title
I am using Buffered reader as of now -
String csvFileToRead = "csvFiles/authors.csv";
BufferedReader br = null;
String line = "";
String splitBy = ";";
[Code] ....
I am confused about how to proceed with multiple files. Here are the approaches that i have considered -
1) change string csv csvFileToRead to a string array -
String[] csvFileToRead = {"data/autoren.csv", "data/buecher.csv", "data/zeitschriften.csv"};
Pass each index each time to a method returning all rows but getting stuck with DS to use. I think ArrayList wont suffice since i need separated data. Should i use a 2D array? Do i need to read and store data in a DS in order to achieve the goal?
2) Should i make 3 different classes with getters and setters for authors, book and magazine?

I written java code in JSP to display data. I know it is bad practice. Actually my Business-service communicates with DB and returning data in the form of MAP. I don't have beans Because the fields in DB is dynamically changing. So, for now I'm retrieving Data by writing Java code in JSP. Is there any other way to display data without writing java code in JSP?

My problem is to read a text file which contains lines of text data
{e.g: #1115=CLOSED_SHELL(",(#166,#208,#250.....#1114));}
I need to break it and #numbers in braces are assigned to string array and they should cal by one by one. similarly next level on calling #166 same operation should perform
{#166=ADVANCED_FACE(",(#165),#129,.F.);}
like this 8 levels were there, finally at each level the Calling number should display in JTable.
