I did or at least thought I create a matrix of Buttons with values inside of them.
I will show code snippets from different classes:
Made into the view class
for(int i=0; i<25; i++){
for(int j=0;j<25;j++)

My IDE says counter cannot be resolved or is not a field. I understand what it is saying but why not? I try my best not to put a bunch of code on here.
<html>
<body>
<form action="login">
Male:<input type ="radio" name ="sex" value="Male"> <br>
Female:<input type = "radio" name="sex" value="Female"> <br>
<input type="submit" value="Enter">
[Code] ....
when the see the result i just get a strange value as "ON" but I am not getting the required value ,I mean Male or Female.
I'm working on a Java/Android program that takes a number input (for example, hour = 7 and minutes = 30 for 7:30AM), and then expresses it on an Analog clock. (hour hand pointing to 7 and minute hand pointing to 30 minutes) ...
How can this be done? Would I need a lot of image files? How to start ...
I am doing an assignment and I am clueless as to what I did wrong or supposed to do in terms of placement of coding.
This is what I supposed to do:
1.) Type the following shell for the class:
public class ParadiseInfo
{
}
2.) Between curly braces of the class, indent a few spaces and create the shell for the main() method:
public static void main(String[] args)
{
}
3.) Between the braces of the main()Method, insert a call to the displayInfo() method:
displayInfo();
4.) Place the displayInfo() method outside of the main() method, just before the closing curly brace for the ParadiseInfo class:
public static void displayInfo()
{
system.out.println ("Paradise Day Spa wants to pamper you.");
system.out.println ("We will make you look good.");
}
This is what I attempted to do:
I know it is wrong I am just clueless on where to put the code and why
public class ParadiseInfo
{
displayInfo();
public static void main(String[] args)
{
public static void displayInfo();
}
system.out.println("Paradise Day Spa wants to pamper you.");
system.out.println("We will make you look good.");
}
--- Update ---
I also tried it this one and ended up with 1 error..
public class ParadiseInfo
{
displayInfo();
public static void main(String[] args)
{
}
public static void displayInfo();
{
system.out.println("Paradise Day Spa wants to pamper you.");
system.out.println("We will make you look good.");
}
}
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 started to create a calculator using Java SWING. I am new to this and don't know a huge amount. I don't know what to do now.
How do I add actions to the buttons? So when the button is pressed it will appear in the text area?

I am learning out design patterns and doing a little fun project on Model Control View (MCV). I got the concept down, it is pretty simple for the most part. However my buttons are not working.
Here is the code:
public class Controller
{
private Model model;
private View view;
Controller(Model model, View view) {
this.model = model;
this.view = view;
[code]....
It runs but nothing. My other questions is how can I make a box that will print the results.
Right now, i'm trying to do is when a user clicks on my GUI button, it would display a text of information on the button they selected. I'm using an arraylist of objects and i'm trying to input the function inside the mouse click function. But I'm not sure how to properly display that information. Here is my GUI code. I'm working on the raven button. I have animal interface, with a parent class of Bird, and child class of Raven. How I could display this correctly...
public class AnimalJF extends JFrame {
private JPanel contentPane;
private JTextArea textArea = new JTextArea();
/**
* Launch the application.
*/
public static ArrayList<Bird> Birdlist = new ArrayList<Bird>();
public static void main(String[] args) {
Birdlist.add(new Eagle());
[Code] .....
So I have a Jframe that has a set of functions that act on a node. What I want to do is allow the user to expand the gui by creating new sets (copies) of these functions when they have more nodes.I thought of hiding extra sets and making it appear they are adding them by making them visible.

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.

Below is where I create a matrix of buttons via Swing
public class View extends Mybuttons{

JPanel matrixPan(){
matrixBtn = new Mybuttons[25][25];

panel.setSize(550,550);
panel.setLayout(new GridLayout(25,25));

private Mybuttons getUnvisitedChildNode(Mybuttons b){

int x= Mybuttons.getComponentAt(b);
int y= Mybuttons.indexOf(b);

I'm just wondering whether it is possible to use images as a button in Java. I have two images that I want to use to create a rollover effect, is this possible? And then I would like to reset my java program when the button is clicked, is this also possible?
View Replies View RelatedI'm learning the swing options of Java, and my first exercise was the typical Chat Room. I got everything right: TextField, TextArea, the jpanel at left side and the buttons inside of it. BUT I can't order the 2 buttons (1 north, 1 south). I've already looked for answers, but didn't find anything and I tried to asked the teacher, but she was too lazy to look for the error. Here is my code:
f=new JFrame("Chat Room");
b1=new JButton("Send");
b2=new JButton("Emoticons");

p1=new JPanel();
f.getContentPane().add(p1,BorderLayout.EAST);

I have a GUI with a menu to do various options. However I want to change that menu to use buttons instead. I'm working with JSwing components and I'm a little familiar with the JButton function, but I don't know how to convert the menu to a button. I think I'll have to remove the menu completely..anyway I tried to start with the file menu but the compiler says no suitable method found for setForeground(javax.swing.JMenu). Why is it giving me an error related to JMenu when I'm using Jbutton objects? Can I not use JButton objects inside a menubar scope? I'll bold the area it highlighted:

After the line 37 executes I expect that the ActionHandler (ah) will be removed from all of the buttons but this do not happen, then all the remaining button still responding to the clicks. Where is the problem in my code.
I'm having an issue with a swing application I'm working on. Java version is 4 (I know...). I have a main screen panel with multiple sub-panels (rows). Each of these row panels contains an additional 2 sub-panels. One of these 2 sub-panels contains buttons. When 1 button is pressed, I want to disable all of the buttons on-screen (or any other way of blocking user input) until a background event finishes. The row panels do not know about each other.
The first thing I have tried doing is, when a button is pressed, getting the parent. Using the parent I then iterate through its components, and so on until I'm iterating through the buttons. For each button, I am doing a .setEnabled(false); However, this does not work, why. I've also tried wrapping this process in SwingUtilities.invokeLater() out of desperation, but that didn't work either.
What would be the cleanest way to disable all buttons? Or block all user input? I've also tried adding an opaque dialog which hasn't worked. Last resort would be maintaining some sort of button list, but I'd rather not.

Program must be jframe that contain 2 buttons and a graphic.
Graphic is any thing car or human or any thing and by changing x-axis of of the graphic it will be as if it walk from place to another.
We must use the function timer that change the x-axis after defined time.
The two buttons are one for stop walking and another for resume.
