how to make a simple JButton on a JFrame window?

can anyone show me a demo how to make a JButton in a JFrame window...
please.. dont have any idea how to do it...


ill make it an input statement for some of my codes here.... i want to try that GUI instead of using JOptionPane's input dialog.


is there any link in java tutorials?

Do you know how to create a JFrame?

Chris

yes of course...

do i need to add the jbutton in a content pane?

i know how to instantiate a Jbutton object. i just dont know how to add it in the frame and how to use it as an input routine

Code :

---

frame.add(new JButton());

---

And you canuse setActionListener() and setActionCommand() to set it up to detect it being pressed.

Chris

If you are using a JFrame, you should make the call to (assuming your JFrame is named frame)

Code :

---

frame.getContentPane().add(new JButton());

---

In most circumstances you would add the JButton to a JPanel, along with any other things necessary (in your case perhaps a JLabel with a message?), then add that JPanel to the content pane, and as Freaky Chris describes add an action listener to the button to lister for events.

ahh so its not that easy to make the JButton as a simple input routine for my program...

any tnx for the information guys,,, ill post any further questions if necessary , coz i dont know how to use such methods...

and i think i didnt post any particular cases in which i have to use a jbutton... im gonna check my console files first.. then ill post any codes here to convert it's input routines into a JButton interface

this one..

Code :

public class SwitchSample4_EnumType {
 
    private static enum Day {
 
        MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
    }
 
    public static void main(String[] args) {
 
        Day day = Day.values()[new Random().nextInt(Day.values().length)];
 
        switch (day) {
 
            case MONDAY: 
 
                System.out.println("Its Monday");
                break;
 
            case TUESDAY:
 
                System.out.println("Its Tuesday");
                break;
 
            case WEDNESDAY:
 
                System.out.println("Its Wednesday");
                break;
 
            case THURSDAY:
 
                System.out.println("Its Thursday");
                break;
 
 
            case FRIDAY:
 
                System.out.println("Its Friday");
                break;
 
            case SATURDAY:
 
                System.out.println("Its Saturday");
                break;
 
            case SUNDAY:
 
                System.out.println("Its Sunday");
                break;
 
            default:
 
                System.out.println("what day is it?");
                break;          
        }
    }
}

how can i make a simple GUI in Jframe for this code... make the switch cases the value for the JBUtton....
get it?

i mean... it will be the value for every button

Here is, in my opinion, the most interesting part:
JAVA Code:

//If first time key in date run statement
if(first == 0){
++first;//Track if is the first record key in
items[i] = new Item(itemNumber, itemDesc, sellPrice, quantity);
}
//Else continue key in record
else{
entries = items[0].getEntries();//Get number of entries entered
for(j=0; j<entries; ++j){

duplicate = items[j].equals(itemNumber, itemDesc, sellPrice, quantity);//Check for duplication of entries

if(duplicate == true) {
Print.duplicateError();
--i;
--looping;
break;
}
}
if(duplicate == false)//else save record
items[entries] = new Item(itemNumber, itemDesc, sellPrice, quantity);
}
