Okay sir. I will do it.

I just downloaded this tutorial which i will study offline and then proceed with my assignment.

Thanx SBU.

Ok, I know that this topic is called "Java for dummies right" so here's some problem solving for dummies,
Who would love to help?

write a program, called RomanNumerals.java, to convert the Roman Numerals
representation of a year into its decimal representation.
Below is the table of Roman Numerals you recall from High School (For more
information on Roman Numerals see http://en.wikipedia.org/wiki/Roman numerals).
Symbol Value
I 1
V 5
X 10
L 50
C 100
D 500
M 1000
Your convertor must convert a number in Roman Numerals representation
in the range I - MMM to its decimal number representation. Also, you know
that your laptop might only be able to handle one execution of your program.
You therefore must ensure that your program will continue prompting for a
Roman Numeral to convert until you enter 0, which will cause your program to
terminate.

Example
You input the year CCLIX (the year in roman numerals), the program then
displays 259 (the year in decimals). You then wish to terminate the program so
you enter 0 as the second Roman numeral.
Sample Run
Enter a Roman Numeral: CCLIX
The year in Decimals is: 259
Enter a Roman Numeral: 0

sbucareer,
Maybe I should put it this way, it's a challenge to me as well, is there a way you can assist me? I want to challenge my mind. I will be asking you many questions like this often. That's how I challenge my programming skills; and when it gets too tough, I'll come to people like you for help.

romeo it's time to learn with fellow naija bros, great work mate!!!

SBU, i am struggling on my knees to get on, i am very busy, am right behind. on temperature classsess. trying to draw the diagram.
i sent u an email sometimes ago didnt knw if you get it or not.

.

@SBU, i have designed it on paper i only need to get it into coding.

I promise this monday (10), i have to suspend all other projects to get it done.

I will submit it.

@upset no no no no, i understand u. There still more for me to gain than getting upset by that. afterall am carrying on with the resources i have with me.

I read the thread but i didnt see that comment u made. I only saw the number calculation

My assignment:

second

Hey SBU, I have just joined this website and thats because I just got to know about it, I mean, I dont know how to commend u on what u are doing, U are doing far more than a great job, I mean, this is what we pay so much money to learn and we still dont get it. I know I am real late on these your tutorials but I am in a JAVA class right now and I aint learning a DANG thing, I added u on my MSN so I can ask u for help if u are willing to offer. I really need to get with the JAVA programming. I can understand a few of what u are teaching but its slightly different from what I am being taught, I want to keep in touch and ask u for help from time to time if its all good,

How about those books/software today is 17/04/2006

I have a problem with my assignment. This is the code below

/**

package temperature;

public class LagosTemperatureView {

private ActionListener listener;
private DocumentListener documentListener;
private ImageIcon Image1;

private JPanel rootPanel;
private JPanel rootPanelTop;

private JPanel rootPanelDown;


private JTextField firstBox;
private JTextField secondBox;

public LagosTemperatureView(ActionListener listener, DocumentListener documentListener){

Image1 =createImageIcon("images/temp_app.gif";
JLabel celsius=new JLabel("Celsius";

this.listener = listener;
this.documentListener = documentListener;




//this.setLayout(new BorderLayout());
//lets divide the root panel for easy placement.
rootPanel = new JPanel();
//we are making it grid layout and setting
rootPanel.setLayout (new GridLayout(5,1,2,2) );
rootPanelTop =new JPanel();
rootPanelMiddle=new JPanel();
rootPanelDown=new JPanel();

rootPanelTop.setLayout(new FlowLayout());
rootPanelMiddle.setLayout(new GridLayout(2,4,2,2));
rootPanelDown.setLayout(new FlowLayout());

labelIcon.setIcon(Image1);
labelIcon.setText("";
rootPanelTop.add(labelIcon);
rootPanel.add(rootPanelTop);

rootPanelMiddle.add(firstBox);
rootPanelMiddle.add(firstPlus);

rootPanel.add(rootPanelMiddle);

rootPanelDown.add(lagTemp);
rootPanel.add(rootPanelDown);


}
protected static ImageIcon createImageIcon(String path) {
java.net.URL imageURL = LagosTemperatureView.class.getResource(path);

if (imageURL == null) {
System.err.println("Resource not found: "
+ path);
return null;
} else {
return new ImageIcon(imageURL);
}
}
public static void main(String arg[]){
JFrame frame=new JFrame("Lagos Temperature";
JFrame.setDefaultLookAndFeelDecorated(true);
LagosTemperatureView cont=new LagosTemperatureView( );
frame.getContentPane().add(cont);
frame.pack();
frame.setLocation(400,100);
frame.setSize(400,500);
frame.setVisible(true);

}
}

/**
*@(#)LagosTemperatureController.java
*/
package temperature;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

import javax.swing.event.DocumentListener;
import javax.swing.event.DocumentEvent;

import javax.swing.JFrame;
import LagosTemperatureView;
/**
* @author Skima
*
*/
public class LagosTemperatureController extends JFrame implements ActionListener, DocumentListener {

private LagosTemperatureView lagosTemp;
public LagosTemperatureController(){
lagosTemp=new LagosTemperatureView(this,this);
}

public void actionPerformed(ActionEvent e){
}
public void changedUpdate (DocumentEvent ev ){
}//End changedUpdate

public void insertUpdate (DocumentEvent ev){
}//End insertUpdate

public void removeUpdate (DocumentEvent ev ){
}//End removeUpdate

public static void main(String arg[]){
JFrame frame=new JFrame("Lagos Temperature";
JFrame.setDefaultLookAndFeelDecorated(true);
LagosTemperatureController cont=new LagosTemperatureController();
frame.getContentPane().add(cont);
frame.pack();
frame.setLocation(400,100);
frame.setSize(400,500);
frame.setVisible(true);

}
}

The above code could not compile.

public void actionPerformed(ActionEvent e)

shouldn't that be

public void actionPerformed(ActionEvent ev)

I will try it out and get back to u. Thanks

sbucareer, why are you making these guys use Netbeans? Making them use Textpad is just plain evil.

Netbeans is a pile of poo (no disrespect to SUN Microsystems, but they are not very good at building commercial software). If your IDE is not IDEA (IntelliJ) or Eclipse, you're causing yourself unneccessary pain.

Also, for those of you intending on "making money" out of some programming career, standard Java (J2SE) will not do you much good. What you need to do is learn the industry tools and APIs.

For a site built with the full J2EE stack check out http://www.naijamovies.co.uk/site/naijamovies.jsp

Peace

What is the point in learning Java Swing? nobody uses it

Please someone should tell me a good websit that teaches everything i need to know about visual basic, i want to download it and brows it offline since my internet connection does not come regularly

And THis was a REALLY nice Thread, whatever happened!!!

Anyway, SBuCareer, whether you come back or not,

YOU 'VE DONE A GREAT JOB FOR STARTING!!! KEEP IT UP, MA MAN OF STATURE!!!

But hoping you guys wud come back

OK Cheers!!!
