我正在编写一个简单的程序来查找电影信息，但在显示 GUI 时遇到了一些问题。我感谢任何人可以提供的任何帮助。

package guiprojj;
import java.io.BufferedReader;
import java.io.Console;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;
import java.net.UnknownHostException;
import java.util.Scanner;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import guiprojj.gui;

import javax.swing.JFrame;

@SuppressWarnings("unused")
public class Test {

    public static void main(String args[]) throws IOException {
        BufferedReader rd;
        OutputStreamWriter wr;
        String movie = null;
        //Scanner s = new Scanner(System.in);
        //System.out.println("Enter input:");
        //movie = s.nextLine();
        //movie = movie.replaceAll(" ", "%20");
        while (movie != null)
            {
            try {
            URL url = new URL("http://www.imdbapi.com/?i=&t=" + movie);
            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
            wr = new OutputStreamWriter(conn.getOutputStream());
            wr.flush();

            // Get the response
            rd = new BufferedReader(
                    new InputStreamReader(conn.getInputStream()));
            String line;
            line = rd.readLine();
            if (line != null) {
                System.out.println(line);
            } else {

                System.out.println("Sorry! That's not a valid URL.");
            }
        } catch (UnknownHostException codeyellow) {
             System.err.println("Caught UnknownHostException: " + codeyellow.getMessage());
        }
        catch (IOException e)
        {
            System.out.println("Caught IOException:" + e.getMessage());
        }

            }
    }
}

和

package guiprojj;

import javax.swing.*;

public class gui {
    public static void main()
    {
        JFrame maingui = new JFrame("Gui");
        JPanel pangui = new JPanel();
        JTextField movie = new JTextField(16);
        maingui.add(pangui);
        pangui.add(movie);
        maingui.setVisible(true);
        maingui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

是我的两个班！

将String数组参数添加到main方法中，gui以便应用程序具有有效的入口点

public static void main(String[] args)
