I want to have a button in my Jsp's labeled "next" that takes me to the next JSP in a certain order. Imagine a book: every time you click next you go to the next page.
Each page is a JSP that is named "page#" where # stands for the number (page1, page2,etc).
I was structuring my app this way: one controller,one controllerhelper,multiple JSPs.
The "next" button in the JSP's would always have the same name as not to overcode in my controllerhelper with too many options for the button that was pressed.
So my idea was to retrieve the name of the current JSP and work the string in order to add a number (page4 turns into page5) and forward it through a requestdispatcher.
That is the problem as I am not able to get the name of the current JSP since the url changes after the first page to the servlet url.
Let's say I have a text file and in the text file exists file directories as such:
'assets/picture1.png'
'assets/picture2.png'
And so on...
How would I then read from this text file and then create those files using 'new File()'?
Here is my code:
private void getFiles() throws IOException{
files = new File[10];
Scanner scan = new Scanner(new File("files.dat"));
int count = -1;
[Code]....
It does print out those files, but it doesn't create them.
Im trying to use num as the text on the button..... (Im trying to make it count when i press the button.)I need to make a listener for the button, and an event that adds 1. (num++)
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.*;
import javax.swing.*;
public class ClickIt {
public static void Practice()

I have been trying to get my radio buttons to display text when they are selected in a textbox but for some reason no matter what i try it wont display. Here is my code i have removed my attempt to get the action listener working.

public class ListVsSetGui extends JFrame {
private JPanel contentPane;
private JMenuBar menuBar;
private JMenuItem mntnListVsSet;

Ok, so I am trying to learn about JFrames and JPanels. I have figured out buttons, layouts, etc. What im having trouble with is accessing the label object from the ButtonHandler class since it is static and I need my JLabel to be non-static so that it can change. Basically, I want JLabel to change to a pre-determined text string once a button is pressed. Here's what I have so far
package makewindow;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
[code]....
why this code doesnt work? Its suppose to be a simple frame with a button that puts text to the frame when u click it. The problem is actionPerformed method, when it tries to call the stuff inside the constructor it all goes wrong. I switched the method body with a system.out.println() and it all works fine.
import java.java.awt.Label;
import java.awt.Button
import java.awt.BorderLayout;
import java.event.*;
public class TheClass implements ActionListener {
public TheConstructor() {

View Replies View RelatedI want to use this class and method with all of my buttons and text fields. My program contains 1 push button that adds questions and answers to a test, 2nd button that starts a test, a 3rd button that scores the test, and a text field that enters the user information. How would this work? I know how to create questions and answers, start a test, and score a test it's just a matter of how to implement the button and text fields. I'll post the code that I have done so far.
See:
private class ButtonListener implements ActionListener{
public void actionPerformed (ActionEvent event)
with all of my buttons and text fields.
import javax.swing.JFrame;
public class TestingDriver
{
//-----------------------------------------------------------------
// Creates and displays the main program frame.

JFrame frame = new JFrame ("Testing Program");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

I don't get what I missed in the code. I used the example of changing the text of a button by clicking on it, but instead I also added a JLabel and tried to make the button change its text instead, but it didn't work. What did I do wrong?

I have problem with my simple program. I tried put some text in my text area using button1 but textListener in RighButtons is always null and it's give me NullPointerException.

BaseFrame

In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+"
Code:"+ncrarray[1]+"
Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) {
textArea_1.setText(text);
} mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
I have a button that bolds all the text in the main div. I am trying to get it to change back to the normal text after it has been bolded. But I cant figure it out. It bolds the text and changes button value when button value is "Bold", but when button value "UnBold" and user clicks button the text does not unbold. Here is my function.
function boldDiv()
{
var button = document.getElementById("firstbtn");
var oldHtml = document.getElementById('main').innerHTML;

I'd like to change the text on the two buttons which I have in my Dialog Box, how should I do this?
Also, when I click the X Button in the top right of the Dialog Box, nothing happens, and the program only stops when I end it in jGrasp. How do I make this button close the program when clicked on?

here i coded out my radio button..i am confused how to get the selected radio button of string and match with another array of String..
Just run the following code and move the mouse next to the text of the button and you will see exactly what I am talking about. Any way to prevent this continuous flash?

I currently building a hotel reservation system, and I'm having issues with retrieving and setting other values from a JTextField.
What I'm trying to do is to retrieve the value that was inputted into a textfield, and then setting that value to a string in another class.
In here, I'm trying to retrieve values from the JTextField:
@Override
public void actionPerformed(ActionEvent event) {

if (event.getSource()==roomView)
{
roomViewFrame.setVisible(true);

How I can retrieve the value of user_id at page userprofile.xhtml?
This program should create a GUI that has 5 classes together on a grid layout. The problem that I am having is that the user input class has the input for kwh, hours, and gallons. I am having problems getting that information from the user input class to the totals class.
user input class:
package applianceutilitycalculator;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Scanner;
import javax.swing.*;
[code].....
The totals class should take the info from the kwh hours and gallons and do the math to get a total and display it in a JTextField(?).
