问题
I am a beginner to java and I have some trouble on making the doClick buttons. I don't understand how it works and I need it in my code.
JButton easyb = new JButton("Easy");
JButton mediumb = new JButton("Medium");
JButton hardb = new JButton("Hard");
String fn = JOptionPane.showInputDialog("Choose your level \n", easyb.doClick() ,mediumb.doClick(), hardb.doClick() , "\n \n Easy are words you know everyday \n Medium are words that you have seen before \n Hard are words that you have rarely seen in your life");
I want the output to look like this:
Choose your level
easy medium hard ( you can click on the words)
Easy are words you have said everyday
Medium are words that you have seen before
Hard are words that you have rarely seen in your life
Update: Here is my whole code in case you need anything else
import java.util.*;
import javax.swing.*;
import java.awt.*;
public class SWG1 {
public static void main(String[] args) {
int pizza = 0;
while(pizza == 0){

JOptionPane.showMessageDialog(null, "Scrable", "Game", JOptionPane.PLAIN_MESSAGE);
String fn = JOptionPane.showInputDialog("Choose your level \n", easyb.doClick() ,mediumb.doClick(), hardb.doClick() , "\n \n Easy are words you know everyday \n Medium are words that you have seen before \n Hard are words that you have rarley seen in your life");

If you have any questions comment below.
回答1:
You can use a better JOptionPane, the JOptionPane.showOptionDialog:
String[] options = { "Easy", "Medium", "Hard" };
int selection = JOptionPane.showOptionDialog(null, "Choose Something", "Title",
JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null,
options, options[0]);
// ***** oops! this should be >= 0, not > 0. Corrected!
if (selection >= 0) {
System.out.println("Selected: " + options[selection]);
}
Edit
From your comments:
The button part works but I have two problems. The first is that I don't think it will show how I want the output to be like I said in my question. The words need to be there as well.
All you need to do is put in if/else blocks or perhaps better, a switch statement that outputs the correct String based on which option was selected, 0, 1, or 2.
e.g.,
if (selection >= 0) {
String word = options[selection];
case selection 0:
// output stuff based on easy
break;
case selection 1:
// output stuff based on medium selection,....
break;
//.... etc.../
}
The second problem will show the whole code and then you can see the problem.
I see your whole code, but I don't see a specific question pertaining to it.
Edit 2
What Ordous is suggesting is that you create a JPanel with your 3 buttons, give them ActionListeners, and place that JPanel into a JOptionPane or into a JDialog, and display it.
