Populate JTable With Input From JTextField And JComboBox
Dec 4, 2014
I am trying to populate a JTable using Several JTextFeild a JComboBox and a JLabel.
The textfields are originalPrice and itemName
JComboBox is departmentComboBox
label is salePriceLable.
When hitting the button i need the program to calculate the price after discount and add the item name, department, original price, and discounted price to a table. I have the calculation down, but am lost on populating the table.I used NetBeans 8.2
/*
* Program: JavaRetailCalculator
* Purpose: To calculate the ammount of a discount and display results in a Table
*/
import java.awt.*;
import javax.swing.*;
public class CalculatorFrame extends javax.swing.JFrame {
/**
* Creates new form CalculatorFrame
*/
public CalculatorFrame() {
initComponents();
[Code] .....

I am designing a advanced search option in a java project with sqlite in NetBeans. there are 5 different JTextfields and 5 columns, I want to populate JTable with corresponding matching criteria. If a JTextfield is empty then it should select all items of that column.
query i was using is:
String val1=txt_billing2.getText(); //five input fields
String val2=txt_station2.getText();
String val3=txt_invoice2.getText();
String val4=txt_amonth2.getText();
String val5=txt_umonth2.getText();
[code]....
but when i leave a JTextfield empty it shows no data in JTable. only method i know is to use if else conditions but that generates 5!= 120 conditions!!!

I'm trying to populate my JComboBox with an Arraylist. Using two different classes, a GUI class (with the JComboBox - called it MainGui) and a class where I extract information from a database and put it into an ArrayList (which I call databaseconn).In my databaseconn class, I can print out the content of the ArrayList perfectly fine, but when I try to do it in my GUI class it just prints empty brackets "[]".(What I need it to do is to populate the drop down list in the JComboBox with the hotel information).Here's my code:
//The dataaccesslayer you should use for classes that deal with connection to the database
package dataaccesslayer;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
[code].....

I need to take the value of what's typed in my JTextField, and once the submit button is clicked, I want to add that string to my JComboBox list items.
Depending which RadioButton they selected, I need to put the team in HOME or AWAY teams, and so on and so on, until they continue clicking submit.

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.
public class LeftPanel extends JPanel {
private static final long serialVersionUID = -2311952438693382407L;
private RightPanel rPanel;
public LeftPanel(){
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);

I'm making a project about school management system , i have a jframe to set marks and inside the jframe i have a jtable which is connected to sql database , in the jframe I have a JCombobox with 6 different subjects and in my database i have created 6 tables for the subjects and if any of the subjects are clicked then the jTable will connect to database and change the table to that subject , after it is changed if you double click on any row and insert a value then it will automatically update the table in the database , but my problem is that if I select the first option from the jcombox which is English and edit the values then it works fine , but if I select any other option e.g Math or Science , then I try to edit the table then it edits the English table , I commented the English option in the code to see what happens and I saw that it edits only the first option and if you try to change the subjects and edit than it edits the first subject in the combobox , so how can I solve this ?
CODE:
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JLabel;
import java.awt.Font;
import javax.swing.JComboBox;
import javax.swing.JTable;
[code]....

My question is related to combo boxes. A combo box in general is a text field with a dropdown list. I would want to know if we can replace hthe dropdown List by an other component, for example a JTable component.

How would I display certain output text if the text entered equaled "text".
So lets say you enter a question into a JTextField. You press a button that submits the text. The output displayed depends on what the question you asked was.
Think about it as "If question = What color is the sky? On submit, display text "Blue". How to implement this.

I have a GUI with a JTextField. I need to check that the input entered by the user is made up of only integers.
For example I accept: 1, 10, 530, ...
I do not accept: -10, 1.5, -6 ...
I would like to implement this control by using a regular expression so I would have a code like that.
JTextField text = new JTextField();
String input = text.getText();
boolean bool = checkInteger(input);
if(bool)
System.out.println("Ok");
else
System.out.println("Error");
The checkInteger(String input) method should check if the input string is correct or not.
How can I do to implement this control with regular expressions?
Is there an easier way to do it?

I'm trying to get data from a GUI input window into an ArrayList and back out via a JTable. I can get the array lists to print to the console within the input class, but I need to wire it to a data container and out through a different class. Here is code from one input class, and its corresponding output class:
Input:
public class AddClassroom extends JFrame implements java.awt.event.ActionListener {
// UI components
// are declared here...

I am having trouble taking user input and passing it to another class as a variable. If I assign the value explicitly (see line 59), it works just fine. What I want to do though, is assign the input from inputField to the variable inputVariable. I tried using:
inputVariable = inputField.getText();
This does not work. Regardless of what is typed into inputField, the output I get is just:
"The user typed "
package example;
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;

I am required to read user input to create two matrices which will eventually be added together. I am unsure as to how I can read the input from the user as an int and not a String. The input is from size 0-10 for both column and row size. Also, can you have a new button created in the actionPerformed method of a previous button?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class Matrices implements ActionListener {
private JFrame win1, win2, win3, win4;

I have been creating a Java program to track inventory using an array. I need to add a search function to it to take a term, input through a text field, and locate a matching instance within the array. How can I code a JButton to grab test input from a JTextField and search for it within the array then display the corresponding information? I also need to add buttons to add and delete items as well.

I want the form to pull in the values from the Database. I have a connection and I'm able to populate a table with the values.
Now I'm trying to populate a dropdown within a form that will bring in currency codes that are in a column called CURR_CODE from the Database.
<%
//Declare variables
//String con_currency_sdo = ""; // as New Connection
String ResultSet = "rs"; // as New Command
String Statement = "stmt"; // as New Recordset
String selBaseCurr = request.getParameter("CURR_CODE");
