How can I do that in a JSP page.
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JFrame;
public class JLeftOrRight {

I'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");
public void showWindow(){
p1=new JPanel();
f.getContentPane().add(p1,BorderLayout.EAST);
p1.add(b1,BorderLayout.NORTH);
p1.add(b2,BorderLayout.SOUTH);
}
I have to make a ABC learning game , for example when "A" button is clicked ,three images will appear on the Panel including Apple, which I have in my array. I am trying to set three buttons on this JPanel so that I can set ImageIcons on them, but , the buttons are not appearing, and when they do, it cannot be aligned at the center. All I want to do is to set three buttons where the black blocks are. I want to put Images on a buttons because later I need to add AcctionListener on them.
here is my code for my JPanel
public class AbcGeniusPanel extends JPanel implements ActionListener{
//Declare the necessary Variables here
private final JButton[] buttons; //create an array for buttons
private BorderLayout layout; //Declare object of BorderLayout

Am trying to add buttons dynamically in a new Jpanel on click of a button. i am getting new Jpanel but not able to see the buttons.

prepareHandsForGuiCode is
public UNODeckMain prepareHandsForGui(UNODeckMain unoDeckMain){
JButton[] btnArr =new JButton[50];
for(int i=0;i<50;i++){
btnArr[i]=new JButton("hi");
panel_player1.add(btnArr[i]);
}return unoDeckMain; }
Am i skipping something ?
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 making a game in java and i want to make a title screen. What I am trying to do is make a jpanel and load another jpanel when a button is pressed in one of the japenls. Here is the code for the runner

public class Runner extends JFrame {
// Have these set up so they can be seen everywhere

I have a Main() class that extends JPanel and I'm trying to add Card() that also extends JPanel.When I add a Card() or Main() object to the JFrame directly, it works fine. The problem arises when I try to add a Card() object to the Main() object.
I edited the code a little bit to make it easier to read so hopefully it's fine.
Main() code:
public class Main extends JPanel implements Runnable {
// HARDCODED OPTIONS
public static final int WIN_WIDTH = 1200;
public static final int WIN_HEIGHT = 800;
public static final int GRID_X = 9;
public static final int GRID_Y = 5;

setVisible(true);
}
public static void main(String[] args) {
C1 c = new C1();
}
}
Why? I tried everything I googled.

I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:
1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error.
2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]
But it is giving 40. Code is as below:
class Base{
int value = 0;
Base(){
addValue();
}
void addValue(){
value += 10;

So I am trying to make this java applet that will display a random image of three that is a sub folder of my src folder within my project.
When you run the project currently all you get is a white applet. Here is the code:
import java.applet.Applet;
import java. awt.*;
public class myPictures extends Applet {
Image action;
public void paint(Graphics g){
int rint = (int)(Math.random() * 3);
if(rint == 0){
action = getImage(getDocumentBase(), "../../images/bee3.jpg");
} else if(rint == 1){
action = getImage(getDocumentBase(), "../../images/bee1.jpg");
} else {
action = getImage(getDocumentBase(), "../../images/bee2.jpg");
} } }
I thought that simply constructing a progressmonitor would show the dialog, and wrote the following code.
[Code] ....
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
import java.util.Random;
[Code] ....
But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?
class connection {
public static void main (String[] args ) {
String a= "jdbc:oracle:thin:@//erp.oracle.com:1521/orcl" + ","+ "apps" + "," + "apps";
System.out.println(a);
System.out.println(coninfo());

I am watching BrandonioProductions on youtube. His videos are pretty good, but he doesn't seem to get errors where I get them. Here is an example.
public class compareUnequal {
public static void main(String[] args){
compareTwo();
}
public static void compareTwo(){
String x = "david";
String y = "Notdavid";
if (!x.equals(y)){
System.out.println("Not equal");
}
}
}
It runs ok, but asked me to proceed when there is an error, but I can`t figure out where the error is!
Whats wrong with my code? The data from my database is not showing on my combo box.. I am trying to get my data in my database to my combo box ..

String db = "purchasedb";
String driver = "com.mysql.jdbc.Driver";
String user = "root";

This is my code for the driver class:
import java.util.*;
public class SavingsAccountDriver {
public static void main(String[] args) {
System.out.printf("%10s%10s%10s%10s%10s" , "Month" , "Account #" , "Balance" ,
"Account #" , "Balance");
[Code] .....
Here is the output I get :
Month Account # Balance Account # Balance
----- --------- ------- --------- -------
0 10002 2000.00 10003 3000.00
1 10002 2002.00 10003 0.00
2 10002 2004.00 10003 0.00
3 10002 2006.01 10003 3030.00
4 10002 2008.01 10003 0.00
5 10002 2010.02 10003 0.00
6 10002 2012.03 10003 3060.30
7 10002 2014.04 10003 0.00
8 10002 2016.06 10003 0.00
9 10002 2018.07 10003 3090.90
10 10002 2020.09 10003 0.00
11 10002 2022.11 10003 0.00
12 10002 2024.13 10003 3121.81
Why is it not showing those months updated balance? I feel like I'm pretty close. I guess I should specify that this is supposed to calculate monthly interest for one account and quarterly interest for the other. This is what the output should look like.
Month Account # Balance Account # Balance
----- --------- ------- --------- -------
0 10002 2000.00 10003 3000.00
1 10002 2002.00 10003 3000.00
2 10002 2004.00 10003 3000.00
3 10002 2006.00 10003 3030.00
4 10002 2008.01 10003 3030.00
... ... 12 ... ...
The quarterly interest is the one that is giving me trouble.
I had to make a table showing different values for converting kg to lbs and I'm confused because when it compiles, some of the decimals show correctly and some of them show with several 0's added on with another number on the end. I've tried to do math.random, but I'm not sure how to tie it in with my program.
//1 kg = 2.2 lbs
public class kg_to_lbs {
public static void main(String[] args) {
//not sure if values are needed..
int kg = 1;
double lbs = 2.20;
//Table title
[Code]...
and this is some of the results I get
1 | 2.2
2 | 4.4
3 | 6.6000000000000005
4 | 8.8
5 | 11.0
6 | 13.200000000000001
