There is one button called Watch Setting in CodeRanch which has 3 options for user to choose


Let say If I have interested on Android forum, I can click that Watch Setting button and choose Watch for new topics in this forum. So everytime there are new posts created, I will receive an email notifications.

DaniWeb so far don't have such feature right?

Hi,if I have interested on one of the forum, example post which has Java tag, can I receive notification if someone is posting on that forum?

Can you show us the code you have tried?

I not really familar with C++, but the error seems like you trying to return a value in void function, which is illegal.

Try replace the void with the return value datatype.

float Saltax::get() {
    cout << "Enter the salary:";
    return x;

Don't forget to change this

float get();

Also, I don't think void main() is allowed in C++. Shouldn't it be int main() ?

Maybe you need to install Java Advanced Imaging (JAI) as well.

When we build an application, which layer should we start with?
From top (UI) to bottom(Data Layer) or bottom to top?

@James, is there a way we can know whether the license allow us continue to use?


I making an android app which need to display data analysis in Gantt Chart.
I implement this library from https://github.com/PhilJay/MPAndroidChart and it runs smoothly in my app.

But what I'm worrying is if this library has been removed from github repo, will my app get effected?

C Language is used to be considered as most powerful programming language.

Where you get such info?

The bug haven't fixed.

Your class is already extend to JFrame. So you don't need to create a new JFrame instance.

public class BusPayment extends JFrame {

    private JButton paynow;
    private JButton cancel;
    private JComboBox<String> jComboBox1;
    private JFrame frame;
    private JLabel label1, label2, label3, label4;
    private JPanel panel1, panel2, panel3;
    private JRadioButton destination1;
    private JRadioButton destination2;
    private JRadioButton destination3;
    private JRadioButton destination4;
    private JRadioButton destination5;
    private JRadioButton destination6;
    private JComboBox company;
    private JTextField passengerstextfield;

    public BusPayment() {

    private void buildPanel() {
        panel1 = new JPanel();
        label1 = new JLabel("Welcome to the Express Bus Ticketing System! ");
        panel2 = new JPanel();
        label2 = new JLabel("Number of Passenger(s): ");
        company = new JComboBox();
        passengerstextfield = new JTextField(8);
        label3 = new JLabel("Selected Bus Company: ");
        final JComboBox<String> comp = new JComboBox<>(new String[]{"Company1", "Company2", "Company3", "Company4"});
        panel3 = new JPanel();
        label4 = new JLabel("Select a ticket: ");
        destination1 = new JRadioButton("Destination 1 RM15");
        JRadioButton des1 = new JRadioButton(Double.toString(15));
//        des1.add(des1);
        destination2 = new JRadioButton("Destination 2 RM18");
        JRadioButton des2 = new JRadioButton(Double.toString(18));
//        des2.add(des2);
        destination3 = new JRadioButton("Destination 3 RM15");
        JRadioButton des3 = new JRadioButton(Double.toString(15));
//        des3.add(des3);
        destination4 = new JRadioButton("Destination 4 RM12");
        JRadioButton des4 = new JRadioButton(Double.toString(12));
//        des4.add(des4);
        destination5 = new JRadioButton("Destination 5 RM16");
        JRadioButton des5 = new JRadioButton(Double.toString(16));
//        des5.add(des5);
        destination6 = new JRadioButton("Destination 6 RM13");
        JRadioButton des6 = new JRadioButton(Double.toString(13));
//    des6.add(des6);
        paynow = new JButton("Proceed");
        paynow.addActionListener(new PayNowListener());
        cancel = new JButton("Cancel");
        cancel.addActionListener(new CancelListener());

        panel3.add(cancel); ...

Does the Momo still appear on Youtube?

Yes, I have received email now. Thanks

Hi All,

Thanks for the reply. I have tested and it works fine.
I will share the screen shot next time if this issue happened again.



public static void main(String[] args){

I got null pointer exception because you did not initialize frame.

frame = new JFrame();

Geanna Afera commented: Oh I see. Is there anything else that is wrong in my code? +0

We need to see your code in order to help

Parents please be aware and very cautious of what your child watches on YouTube and KIDS YOUTUBE. There is a thing called ‘Momo’ that’s instructing kids to kill themselves, turn stoves on while everyone is sleep and even threatening to kill the children if they tell their parents!!!


Are there any differencies between these two code ?

    if (!a.equals("")) {


  if (a!="") {

When posting code, I get error

begin a line with 4 spaces in a row (or one tab), preceded by a blank line. 4+ spaces or tabs may not be used anywhere else.

And who is the youngest member here ?
