I am creating a program to store Product information. Anyone know how to create auto fill function on java??
example:
when i fill productID, the product's name should be filled automatically >,<?
Anyone has solution ??

You more than likely would need some thread that automatically checks the current string in the textbox against the current products. That is a really interesting thing, i will look into it and see what i can come up with

This is a pretty cool thing, at the moment i have just setup a very basic and inefficient way of doing things. Basically i have added a KeyListener interface on the JTextField and each time an ActionEvent is fired i just iterate a list and update a JLabel containing a suggestion of what the word may be. It is very ghetto and i will look at implementing something better.

I will just put this out there until such time as i address it further. It works somewhat, however is far from complete or perfect. Should help you get started.

public class Main extends JFrame implements ActionListener, KeyListener {

    private LinkedList<String> words;
    private JButton btnOk;
    private JTextField txtInputField;
    private JLabel lblOutput;

    private Main() {
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        this.add(btnOk);


        // Just add some words
        words = new LinkedList<String>();
        words.add("dream");
        words.add("dreamincode");
        words.add("in");

        words.add("isftw");

    }

        lblOutput = new JLabel("Output Info");

        if(evt.getSource() == txtInputField) {
            String suggestion = "unknown word";
            String current = txtInputField.getText();

            for( String s : words ) {
                if( s.contains(current.subSequence(0, current.length()))) {
                    suggestion = "perhaps : " + s;
                    break;
                }
            }
            lblOutput.setText(suggestion);
        }
    }

    public void keyReleased(KeyEvent evt) {
        
    }

    public void keyTyped(KeyEvent evt) {
        
    }

Wow Awesome Job , i was thinking about key binding..it still inefficient to use.

thanks for the answer

Yash... what an horrible solution. There are better ways of doing that

[DaneAU]

Yea i have come to realise that there are better ways indeed. It would be a pretty handy thing for my current application, so i will put up a snippet once i get it working right Don't use a thread or you could run into problems.
