Java Applet

[WillHorne]

I'm trying to write a segment of code that will take text from a textbox and print out some info about what was in the textbox. and have it print out somewhere on the applet


E.G.

Restaurant entered in textbox
search button clicked
print out underneath - All restaurants have air-conditioning


there will be several things that can be entered into the textbot to get different info about all of them




Any Help is welcome



Thanks

Will

So....what did you try? Where are you stuck? Do you know how to create an applet?

[WillHorne]

ive got the applet made its just this little bit that needs finishing

ive got the text box and the button made and can get it to print out preset text in the console in eclipse
what i cant work out how to code is
if "A" is entered into the textbox print "a" next to the textbox
if "B" is entered into the textbox print "b" next to the textbox

[Tolls]

So you need to get the value from the Text box.

Are you able to do that and print that to the console?
If so can you then put that value into a JLabel next to the text box?
Once you can do that, then you just need to find a way to lowercase a character.

[WillHorne]

this is the code ive got for the text box and button

{
Button okButton;
TextField nameField;
{
setLayout(null);
okButton = new Button("Search");
nameField = new TextField("",100);
}

{
okButton.setBounds(140,20,160,25);
nameField.setBounds(20,20,100,25);
}

{
add(okButton);
add(nameField);
}

}

ive taken out all the ActionListener events as they weren't working properly.

im not clued up on the AWT of JAVA 2.0 so dont know how jlables work


could you walk me through it with some examples

thanks Will

[Tolls]

For starters you should be using Swing.
AWT is old, to say the least.

But you said you had the button printing to the console.
That's your start point then.
Get an ActionListener on the button that prints something to the console.

[WillHorne]

this is what i hat to start with but now its now working for some reason

{
Button okButton;
TextField nameField;
{
setLayout(null);
okButton = new Button("Search");

nameField = new TextField("",100);
}

{
okButton.setBounds(140,20,160,25);
nameField.setBounds(20,20,100,25);
}

{
add(okButton);
add(nameField);
okButton.addActionListener(this);
}


public void actionPreformed(ActionEvent e)
{
System.out.println("Hello");
}
}

[doWhile]

but now its now working for some reason

Word of advice: you really have to be a lot more informative with your posts. Saying 'not working' is as useful to us as us saying 'then fix it' is to you, and posting small code snippets in lieu of an SSCCE leaves us guessing. Does it compile? Exceptions? Misbehave?

[WillHorne]

this is the entire applet now

I worked out what i had done wrong

this now prints out to the console when the button is clicked

how do i make it so it prints to the applet

and so that depending on what is entered into the textbox is printed out

How to write an SSCCE

[doWhile]

this is the entire applet now

My post above was there to help, not to be ignored. That is NOT an SSCCE, and to be blunt expecting someone to wade through all that code can be considered rude.

[WillHorne]

sorry

there is no need for an SSCCE as the only bit i need help with is the text box and button. there is nothing else in the applet that affects them.

this is the coding i have for the button.


{
Button okButton;
TextField nameField;
{
setLayout(null);
okButton = new Button("Search");

nameField = new TextField("",100);
}

{
okButton.setBounds(140,20,160,25);
nameField.setBounds(20,20,100,25);
}

{
add(okButton);
add(nameField);
okButton.addActionListener(this);
}


{

}
}

}


public void actionPerformed(ActionEvent e) {


System.out.println("Hello");

}
}

what i would like to know is if there is a way to print out onto the applet
and if there is a way to print out something relevant to the text put into the textbox

[doWhile]

That is the exact purpose of an SSCCE, which makes me think you need to read the link that Diargg kindly provided above.

what i would like to know is if there is a way to print out onto the applet

Define 'print'. If you mean display to a user, the use some other appropriate Component (JTextField, JLabel, etc..) and set its appropriate value to be displayed.

[WillHorne]

i did read that link and there was nothing there that applied to the work i'm doing

and yea i meant to display it to a user

i'm not familiar with Jlables.

could you give me an example of how they work

Thanks

[doWhile]

You then don't understand its purpose - it applies to help others understand the problem, phrasing code concisely without the mess of everything else, and hence help yourself get help.

could you give me an example of how they work

Did you try a web search? This should be the top hit, as well as the first place to go for tutorials and Links to the API: How to Use Labels (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components)

[DarrylBurke]

Presumably you mean JLabel. Please take care to capitalize class names correctly, also to use a capital letter at the start of each sentence and for the first person singular "I" -- and use apostrophes and other punctuation to make your posts easier to read.

Have you gone through this How to Use Labels (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components) ? It's linked from the JLabel API. You have read the API -- or haven't you?

edit A minute too late!

[Tolls]

So now you;re on step 2 of my little list above.
Putting the value you are currently printing to the console into a JLabel.

As has been said, do an SSCCE. That is produce some code that simply has a JButton, a JTextField and a JLabel.
Add the ActionListener to the JButton and get it to set the value in the JLabel.

Note I am referring to Swing classes here.
If you are insisting on using AWT ones then you'll have to dig out the equivalent ones. I've been doing this for over a decade now I've I've never written an AWT app. That should tell you how dated that is as a technology.

[WillHorne]

ive been looking at the Swing tutorials and there not making any scene to me

either i'm looking at them in the wrong way or it going right over my head

how do you get the JLabel to display when you click the action button?

thanks

[Tolls]

You don't.
You have an empty JLabel already there and then set the value of it and repaint (actually that last part may not be necessary).
The JLabel will always be displayed...it'll just not have anything in it until you set the value.

[WillHorne]

how do you set a value to the JLabel

and can you use Jlabel to show something different depending on what is entered into the text box?

Thanks
