as 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.

the code is given below:]
private void jRadioButton1ActionPerformed(java.awt.event.Action Event evt) { // TODO add your handling code here: int LIMIT = Integer.parseInt(jTextField2.getText()); int ULIMIT = Integer.parseInt(jTextField3.getText()); { DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
Everything is working great except for my back button at line 172. It works good but if I try to click the "insert" button again. It gives me the java.lang.NumberFormatException error. Other than that it works fine, the "insert" button still works.
package userDatabasePack;
import java.sql.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Database{ //Variables private String username2, insertUser, insertPassword; private int insertUserId;

In my code where the Button Action Performed is created, I have done the following to ensure that the visibility of the JTable and JScrollPane have been set to true. But it does not work?
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 at com.tutorial.main.MouseListens.mouseClicked(MouseListens.java:22) at java.awt.Component.processMouseEvent(Unknown Source)
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 :
public class ToPortal implements Strategy { 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?
Here's my coding so far...I want to be able to change what the JLabel says when clicking on one of the buttons for example : when clicking on UP i want it to say "Going Up!"...how do i do this?
import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JButton; import javax.swing.JLabel; public class BorderLayoutJFrame extends JFrame {
i have made a phone directory and i have also maintained a database for this. i want on clicking the next button each row from database table display one by one on the GUI into their relevant text Fields. i have written this code , this code show the last row of the table on single click on next button. i want one by one row on each next button click.
I have added a windowListener to my JFrame but for some reason it is not being called when I click X to close the window. I need to send a message to a server to notify it that the client window is closed. Some code snippets below (some lines excluded for brevity):
public class ChatGUI extends javax.swing.JFrame { .... setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); // I have all the window constants here but has no effect other than closing the window without calling the listener... addWindowListener(new java.awt.event.WindowAdapter() { public void windowClosed(java.awt.event.WindowEvent evt) { formWindowClosed(evt); } }); .... private void formWindowClosed(java.awt.event.WindowEvent evt) {
Is there a way to disable sorting by clicking on the JTable headers?I have tried a few ways but because I am sorting the data when I load it that 'breaks' that also. Here is what I am trying to achieve.
I only want the context menu to be showen if the user is clicking on an actual listview item, not if they click anywhere else in the listview. I know this is possible and I found answers to similar problems, but in the end they didn't provide enough infomation for me to solve my issue. I found this example on how to do it with a list view containing String objects, but what if my list view contains another object, in my case a wrapper class? I have a wrapper class to keep track of the key, but I only display the value variable in the listview, through calling the toString method. So the cells still contain a wrapper.
class Wrapper(int key, String value) { .. } public String getValue() { return value; } public SimpleStringProperty getValueAsProperty() { return new SimpleStringProperty(value); } public String toString() { return value; }
[Code]....
But line 05 gives me a NullPointerException, why? I do this after I've set the items of the list view by doing listView.setItems(..).
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
I am using JS, how we can make focus to a button during onload, the button need to get focus which is in tabbedPane tab Name : (Search Critera1) using javascript.
I have a textbox called "answer" and 10 different buttons on a form. Now what i would like to do is click the button and have the Button Text in the textbox with the already present text.
So if i click the button 1 it should automatically recognize the clicked button and have its text copied to textbox.
I know the '.get' method but lets say i have 100 buttons so i cant repeat it for every single one of them.
i want to make adding into mysql database and then when i click adds, jtable show those data automatically. but it seem to get error at display part, it shows " Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Uncompilable source code - illegal start of expression" and jtable do not show the added data but in mysql, data is properly kept.
private void jtPropertyChange(java.beans.PropertyChangeEvent evt) { DefaultTableModel model = (DefaultTableModel) jt.getModel(); try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection(url, user, password); String sql = "SELECT * FROM `companya`";
