What should be the code if i want to input a different string in case of the typed string. The case is : I have a predefined string S = "Peter,please answer my question" and now when i input another string inside the text field character by character i want characters from the string S to enter instead of the input string. In short, the input string should be disguised as string S.
View Replies View RelatedI have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.
ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...
I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name
ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....
What am i doing wrong here, and how can i fix it to where it fills out the correct data?
Here's my code so far:
public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;
[code]...
I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.

I have list of employees in my database and their associated information like employeeId,supervisor and process. I have class named EmployeeDetails having same properties. I am fetching details of all users using below code:
<%EmployeeDetails employeeList;
employeeList=(List<EmployeeDetails>)assetmain2.getEmployeeList(loginName);%>
<table>
<tr>
<td>
Requested For <select name="requestedForName" id="requestedForNameID">
<option selected="selected">--Select--</option>
<%int i=0;
[Code] .....
In employeeList, we have list of objects having data of employees. I donot know how to get which object is selected in dropdown and based on that rest of the text fields are populated. Example:
Name ID Supervisor
-------------------------------------------------------
Pawan Kumar3033045Vimal Kumar
Vimal Kumar3040901Dinesh Hemrajani
If Pawan Kumar is selected from dropdown then '3033045' and 'Vimal Kumar' should get populated.

View Replies View RelatedI wrote a simple random spelling game for a class project, was never able to get the labels to update when they should. I have tried .updateUI, .paintImmediately followed by .revalidate and by .repaint. Nothing seems to be working.
What the game does is show a random word for about 10 seconds, disappear and they user is to spell that word, you have 3 tries then will start over. The "brains" of the game work just fine, it is the labels updating with new text when they should doesn't seem to be working. There is 4 classes but the below is the "Main" that has the problems. Also have a null exception problem with the timer.stop(); not sure why. I am still pretty new to java.
Public class SpellMe extends JFrame {
// variables
JPanel mainPanel, secondPanel, thirdPanel;
JLabel mainLabel, wordLabel;
String spWord, sp;

"b" : "hello"
}
{
"a" : null,
"b" : "hello"

I was wondering if it's possible to do this: I want to build a java program that reads a java array from a text file.
Then I want to read it, and output it in a different format.
The reading and out is easy - as text.
But how can I incorporate the read text in to a java valid array in my program, which I can use?
Is this even possible?

Budget program. Here is my situation, I have 2 tabs in a GUI, one tab adds a transactions when the add button is clicked, and in the other tab displays a table showing all the transactions. In my code, I want it so that when the user chooses a deposit(combo box variable name = cbType, indexnumber for deposit is 0) it will add to the total and when the user chooses withdraw(index number is 1) then it will subtract it from the total. Here is the code.... (note as well, the code also adds a new row to the table)
//add button clicked
private class BtnAddActionListener implements ActionListener {
public void actionPerformed(ActionEvent arg0) {
((DefaultTableModel)table.getModel()).addRow(new Object[]{
cbMonth.getSelectedItem() + "/" + txtDay.getText() + "/" + cbYear.getSelectedItem(),
cbCategory.getSelectedItem(),
[Code] .....
So when I tested the program with 2 transactions, the first transaction was a deposit and the 2nd transaction was a withdraw. The end product was that both amounts were subtracted from the total. When I did a withdraw first and a deposit second, the amounts were both added together.
the below program is to read the time intervals (HH:MM) and to compare system time if the system time between your time intervals print correct time and exit else try again to repeat the same thing. By using StringToknizer class. and i have written like this
import java.io.*;
import java.util.*;
public class Main
{
static int k1,k2,v1,v2;
public static void main(String args[]) throws IOException
{
DataInputStream o=new DataInputStream(System.in);
[Code] ....
but is showing correct for some inputs and wrong for some inputs ....
public void paint(Graphics g) {
g.drawImage(Background, bg1.getbX(), bg1.getbY(), this);
for(int i=0;i==400;i+=10){
g.drawImage(block1,fg1.getBlockX(),fg1.getBlockY(),this);
g.drawImage(block2,fg1.getBlockX(),fg1.getBlockY()+10,this);
}
}
This is what im dealing with right now. When i click run i only get the background image showing the other two are not showing on the screen.
I am trying to declare fields as protected String custom.field.1096; in my java class but it does not allow me. Can I not declare the field as above? Is there any workaround to achieve this?
View Replies View RelatedThis program is basically complete. It compiles and runs. It is a college course assignment that I pretty much completed but for the last part in which I'm suppose to change the values of all fields and display the modified values using a toString method. Modifying the values of the fields is where I am stuck. I don't think I need to create a new text data file to do this. The instructor only asked that all the values of fields be changed and this was the last part of the assignment so I don't think it involves creating additional ObjectOutputStream and ObjectInputStream objects. I'm getting a NullPointerException error on line 161.Here is the code. I'm also including the input data file.
//create program so that objects of class can be serialized, implements interface Serialiable
//create constructor with 4 parameters with accompanying get and set methods, Override toString method
//create text file with 5 records, create Scanner object,ObjectOutputStream, and ObjectInputStream

We use a Java program to read an XML file and put its content into a database. We also use Date() to get the current date and insert it into a field in database with content from XML file. Everything worked flawlessly until today, the last day of 2013. We are getting 2014 for the year instead of 2013!!! System date shows correct year, so this must not be an issue.
