java - 随机名称生成器(框架内)

Question

我正在尝试创建一个随机生成名称的名称生成器。现在，当我单击该按钮时，它会生成一个名称，但它显示在 Eclipse 控制台中，而不是与该按钮显示在同一窗口中，而这正是我希望它执行的操作。最终我希望能够为按钮和背景(窗口/框架)提供特定的图片。另外，作为奖励，我希望添加一些音乐，一旦您打开应用程序，这些音乐就可以在后台播放。现在，我对 java 还很陌生，我只看了几个教程，但它已经让我走到了这一步，希望我能从你们中学到一两件事。所以请善待，最诚挚的问候。

import javax.swing.*;
import javax.swing.JFrame;
import java.awt.*;
import java.awt.event.*;

public class ClanNameGenerator {

public static void main (String[] args){

    JFrame frame = new JFrame("ExETesT");
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400,350);
    JPanel panel = new JPanel ();
    frame.add(panel);
    JButton button = new JButton("Click me");
    panel.add(button);
    button.addActionListener(new Action());

}
    static class Action implements ActionListener{

        public void actionPerformed (ActionEvent e){
            String[] names = {"test", "Zero", "Club", "Moonkys", "znakes", "SeamOnster", "dnktwhm", "Rambo", "OmG", "siste"};
            String[] names2 = {"Ylos", "zzzzz", "sdsd", "OK"};
            String[] names3 = {"Hei", "ok", "jadd", "så drar vi", "det var det"};

            int random = (int) (Math.random()*names.length);
            int random2 = (int) (Math.random()*names2.length);
            int random3 = (int) (Math.random()*names3.length);

            System.out.println("Your clan name is: "  + names[random] +" "+ names2[random2] +" "+ names3[random3]);


        }
    }
}

如果你这样做，名称将出现在 JFrame 中:

import javax.swing.*;

import java.awt.*;
import java.awt.event.*;

public class ClanNameGenerator {

private static JLabel label;
public static void main (String[] args){

    JFrame frame = new JFrame("ExETesT");
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400,350);
    JPanel panel = new JPanel ();
    frame.add(panel);
    JButton button = new JButton("Click me");
    panel.add(button);
    label = new JLabel();
    panel.add(label);
    button.addActionListener(new Action());

}
    static class Action implements ActionListener{

        public void actionPerformed (ActionEvent e){
            String[] names = {"test", "Zero", "Club", "Moonkys", "znakes", "SeamOnster", "dnktwhm", "Rambo", "OmG", "siste"};
            String[] names2 = {"Ylos", "zzzzz", "sdsd", "OK"};
            String[] names3 = {"Hei", "ok", "jadd", "så drar vi", "det var det"};

            int random = (int) (Math.random()*names.length);
            int random2 = (int) (Math.random()*names2.length);
            int random3 = (int) (Math.random()*names3.length);

            label.setText("Your clan name is: "  + names[random] +" "+ names2[random2] +" "+ names3[random3]);

        }
    }
}
