Swing/AWT/SWT :: Get Values In JDateChooser
Jan 15, 2007
I'm using Java Swings and MySQL database for my project. When I searched in the net for a datepicker in Java Swings I got one from a site which is Open Source. I've added that in my application. It is working fine. I can select the date from the date pickers and can view the values. I've the following problems in that.
1) I want to put the textfield to be read-only or the users cannot edit that part
2) I want to validate the fields before searching, for that i want to get the values in the jDateChooser.

How to get value from jTable? I use mouse click event for my jtable and then, i want to set value to datechooser. Usually my behaviour for get value from jTable to Textfield, i'm using this method.
txtNamaKlien.setText(String.valueOf(jTable1.getValueAt(jTable1.getSelectedRow(), 1)));
And then value from jTable success fill to textfield.
My problem value from jTable not success fill to jdatechooser, i'm using this method
Date tanggal = (Date) jTable1.getValueAt(jTable1.getSelectedRow(), 2);
jDateChooser1.setDate(tanggal);
And I get an error
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Date
I'm using database mySQL
When inserting data, i use this method
java.text.SimpleDateFormat fmt = new java.text.SimpleDateFormat("yyyy-MM-dd");
String formattedDate1 = fmt.format(jDateChooser1.getDate());

The below program ask the user to enter the value of x 1 , Y 1 and radius in separate boxes , What would look nice is if the user can Enter the Value X ,Y and radius in the same box.
import javax.swing.JOptionPane;
public class C3E29GeometryTwoCircles {
public static void main(String[] args) {
// Ask the user to enter the x1 coordinate.
String strNumber = JOptionPane.showInputDialog("Enter the value of x1 coordinate " );
double x1 = Double.parseDouble(strNumber);
strNumber = JOptionPane.showInputDialog("Enter the value of y1 coordinate " );
double y1 = Double.parseDouble(strNumber);
[code]...

I am making use of NetBeans IDE 8.0 to build a GUI. The idea is that I set multiple values received from textfields to textarea. This will enable me print the work. But ONLY ONE value from textfields is set(appear on textarea); the others do not appear at all. Below is example of what I mean:
String s = jTextField1.getText();
JTextArea1.setText(s);
String x =
jTextField2.getText();
JTextArea1.setText(x);
Only one is being set. The rest are not.

I want to have JTextField automatically highlighting the current values for overwriting when the box is selected. Is there a way to do this? It seems like something that might occur in an action listener.

I have a properties file with a set of commands and their meanings (Command = the meaning). I Populated a jtree with the keys from the properties file, now when I click a node in the jtree (key) I want the value of that selected key to go in the panel that sits in my app next to the jtree.

I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().
My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.

I am making a java swing program. I have a main window that opens a JForm window when the user clicks a menu option. Then I have a button on the JForm that closes the window on click. However, I would also somehow like to make the JForm return values to the main window (according to the states of the selector components) when it is closed. How would I go about this? Currently my jForm is a seperate class called "NewGame", and inside the menu item mouse clicked method, I have the following code:
//open new game jform window
NewGame newGameWindow = new NewGame();
newGameWindow.setVisible(true);
newGameWindow.setLocationRelativeTo(null); //center window
Is there something I can add here to get the object's values upon the window's close? Or is there a way I can add that into the button clicked method on the actual jForm?

I need a way to store the pixels values currently on the screen and compare them to the values on the first frame. Right now I'm using glreadpixels as follows:
currentBuffer= BufferTools.reserveByteData(mapSize);
glReadPixels(mapStartX, mapStartY, mapWidth, mapHeight, GL_BLUE, GL_UNSIGNED_BYTE, currentBuffer);
for (int i = 0; i < mapSize; i++) {
if (currentBuffer.get(i) != baseBuffer.get(i)) {
//Do nothing
continue;
}
//Do something
}
This works perfectly fine but turns out to be a real bottleneck, dropping the fps to a third of what it was. Is there any quicker way? All I'm after is speed, I don't even need to show it on the screen if the comparison is made "behind the scene".

I have a question in mind that this is my registration form. I am sending these values from HTML form to server and database. I have question that in my case if I click next to Add Another Mobile no in HTML.then a block is genereated and each time a new name is generated.
My Question is if I click 6 times then 6 name attribute are generated. How can I send and differentiate them on my server side.
Because at their I will use something request.getAttribute("Attr_Name");
But they are same. How to do this?.

I have a JScrollPane with two coulmns. In the first column I have an image pane JTable, and in the second a list with names of sections. This second column I try to divide in two columns, one (the second column) to display the names of the sections (each row contains one name), and in the other column (the third) I want to show some values for every section in the row respectively. But, instead of displaying the desired values in the third column, I get the same names of the sections as in the second column.

I'm doing an aggregation exercise that's suppose to find the volume and surface area of a cylinder. What I'm trying to do is pass values from one class, to a second class, and that second class passes values to a third class.
This may be a clearer explanation: The first class is the main program which sends values to the second and third class. The second class is used do calculations for a circle (a pre-existing class from another assignment). The third class grabs the values that the second class calculated and calculates those values with the one that was passed from the first class to the third class. The first class then prints the outcome.
Problem is when the program gets to the third class, it just calculates the value from the first class with the default constructor from the second class. It's like the second class never received the values from the first class. I think I'm missing a step, but I don't what it is.
First Class:
package circle;
import java.util.Scanner;
public class CylinderInput
{
static Scanner in = new Scanner(System.in);
public static void main(String[] args)
{
//user defined variable
[Code]...

I have a problem with progress bar implementation to my project. Let me explain it;
I have Jframe named GUI. Filled with 2 datechooser combo box and 1 Buton.
And i have a Swingworker class named "MySwingWorker" for my long running task just like this;
package exampleproject;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.Logger;
[code]....
Just i want add a progress bar for listening MySwingWorker's setProgress updates. When buton clicked swingworker should executed and progress bar should come to screen. I read many articles about that but not understand correctly. Because i am beginner in JAVA.
Question1: Should i (create new class) or (implement to current gui or swingworker class) for progressbar?
Question2: Should i fired progress bar first and execute swingworker from progressbar class? or should i execute swingworker first and fired progress bar later and how?

Is it a good idea to use the factory design pattern for say if I needed to create four different JDialogs for the same parent frame?
factory design interface
package client;
public interface Dialog {
void getInstanceOf ();
void initComponents ();
}
One of the four JDialog class would look something like this without the comments.
package client;
import javax.swing.JDialog;
@SuppressWarnings("serial")
public class AddCustomerDialog extends JDialog implements Dialog{
public AddCustomerDialog () {
//Some stuff goes here to set the settings for JDialog instance
[code]....
Of course you would have your factory class

See the below:
public static void main() {
int i; // counter
createDeck(); // this is a function call
// Show the cards in the deck
System.out.println("The deck is as follows:");
for (i=0 ; i < CARDS_IN_DECK ; i++)
[code]....
It is now printing out the value of myDeck[5] but I need to print out first 5 values.

how can i get id from db table for each column values with java or oracle query? i did get before each column content from file and now i need get the id of this column values from db. I read csv files from folder and then load the data from these files into subfolder, and here with line li = line.split(","); i get the values that i have in csv file and split them and become in li the value name, and then in else block i create a P objekt where i set this values from csv files, and with [I]p.setLid(li);
I set the value for all valuenames, and then get these valuenames in separate column with other content from this csv, and my question is, i need to do this with db, and write these csv file values to the table in db (it will be done with another java class), what i need, that to write the ids of these values into the table in db, instead of valuename, and while there is no ids for valuenames in csv files, i need to get the id from the table in db where these are already listed with sequences.
I don't know how can i write in data table the id of this valuenames and other content, this data table should contain the ids of valuenames timestamp values and the ids of the csv files name, i don't know how to do this with the ids, i must get the ids from the db table and then set these on [I]p.setLid(li); where i set early the valuenames, instead of valuenames i should set ids, that will set ids automatically for all these valuenames.
try {
while ((line = br.readLine()) != null) {
if (lc == 0) {
li = line.split(",");
} else {
String[] temp = line.split(",");
for (int i = 1; i < temp.length; i++) {
p = new P();
[code]....
i got the values that then will be given to [I]p.setLid(li); and iterate, but now i want to get id from the table in db where this values stored with id instead of this column values, how can i do it?

My initial question had to do with looping but now I'm having trouble adding certain variables.
The original thread is here: [URL] ....
If you look at the end of the code it won't recognize the "overtime" and "hourDiff". I have to use it for each level the
user chooses and am not sure how to do so. Even if I put it under the if{ statement it won't calculate. I assume it's due to it being cut off from other blocks but I'm not sure how to combine them.
My code is:
import javax.swing.JOptionPane;
public class Pay {
public static void main(String[] args) {
double salary2 = 20.00;
double salary3 = 22.00;
[Code] ....

This simple program should build a new table with random values and on the getValue method (perhaps called from othe TestClass) return back content of particular cell. why my getValue method doesn't work. Nay! It returns error while compilation.
import java.util.Random;
class TablicaIntowa{
public int getValue(int a){
return tabl[a];
} //getValue method end
[Code]....

I need to compare an int with an array of values generated with a for loop previously. I have something like that for the search..
for( int i = 0; i < 5; i++){
System.out.print("Indovina.. inserisci un valore: ");
// I memorize the value taken input
n = sc.nextInt();
[Code] ....
Also, I need to print the array each time I insert a value that is in the array. But, hiding the values still not "guessed".

I have created a class and a matrix of doubles (or at least, I think I have, that's partly what I want to verify).I need to return the values of the array,Here is my class:
public class example{
double[][] Position=new double[2][11];
double calculate(){
for (int time=0;time<=10;time=time+1){
Position[1][time]=time;
Position[2][time]=time+1;
double A=Position[2][time];
return A;
}
}
}
I am getting the error: "This method must return a result of type double", though to me it looks like I am returning double (A).

I am trying out jsp and servlets now for the first time. I have to insert two data, car code and car name into a mysql table. I got those details using jsp but if I use form, it redirects to another page for insertion. I want the data to be inserted and still remain in same jsp page. I am thinking of using onClick from javascript but as I googled this many places have said it is a bad idea to use jsp inside javascript. If so how can we insert data to mysql table without redirecting to another page?
