Class 如何从GUI Jbutton运行主类？

我已经创建了一个主类（类文件）。就我而言，它工作正常。现在，我正在创建一个GUI，其中包含启动该类文件的按钮。如何为actionListener编写代码以运行mainProgram类

这是主要课程：

import java.io.*;
import java.util.*;

public class MainProgram
{
  public static void main (String args[]) throws IOException
{

//Declare variables            
Scanner in = new Scanner (System.in);  // Scanner used for user input 
BufferedReader inputQuote;
BufferedReader inputTheme;
BufferedReader inputCharacterAnalysis;
BufferedReader inputSignificance;
BufferedReader inputPlotEnhancement;
BufferedReader inputSpeaker;

String [][] quotes;
String text;
int quoteSelection;
int analysisSelection;
int howMany=0;
int count;

  //Count the number of lines in a text file
  FileReader fr = new FileReader ("CrucibleQuotations.txt");
  LineNumberReader ln = new LineNumberReader (fr);
  while (ln.readLine() != null)
  {
    howMany++;
  }

  //import information from the text file 
  inputQuote = new BufferedReader (new FileReader ("CrucibleQuotations.txt"));
  inputTheme = new BufferedReader (new FileReader("CrucibleTheme.txt"));
  inputCharacterAnalysis = new BufferedReader (new FileReader("CrucibleCharacterAnalysis.txt"));
  inputSignificance = new BufferedReader (new FileReader("CrucibleSignificance.txt"));
  inputPlotEnhancement = new BufferedReader (new FileReader("CruciblePlotEnhancement.txt"));
  inputSpeaker = new BufferedReader (new FileReader("CrucibleSpeaker.txt"));

  //Create array based on how many quotes available in the text file
  quotes = new String [howMany][6];

  //Store quote information in the array and display the list of quotations
  for (int i=0; i<howMany; i++)
  {
    quotes [i][0] = inputQuote.readLine();
    System.out.println (i+1 + ") " + quotes [i][0]);
    quotes [i][1] = inputTheme.readLine();
    quotes [i][2] = inputCharacterAnalysis.readLine();
    quotes [i][3] = inputSignificance.readLine();
    quotes [i][4] = inputPlotEnhancement.readLine();
    quotes [i][5] = inputSpeaker.readLine();
  }

  //Ask user to choose the quote they want to analyze
  System.out.println ("Choose a quotation by inputting the number. If the quotation you would like to analyse is unavailable, you may create your own by entering the number 0. ");    
  quoteSelection = in.nextInt ();

  if (quoteSelection!=0)
  {
    //Show user selections to analyze
    System.out.println ("Choose your analysis");
    System.out.println ("1. Theme");
    System.out.println ("2. Character Analysis");
    System.out.println ("3. Significance");
    System.out.println ("4. Plot Enhancement");
    System.out.println ("5. Speaker");
    analysisSelection = in.nextInt ();

    //Display the analysis
    if (analysisSelection <= 5 || analysisSelection > 0)
    {
      System.out.println (quotes [quoteSelection-1][analysisSelection]);
    }
  }

记得打电话

frame.pack();
frame.setVisible(true);

否则将不显示您的JFrame

对于ActionListener代码，您必须为字符串数组维度添加[0]，例如：

  cButton.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent ae) {
            try {
                MainProgram.main(new String[0]);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });

  cButton.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent ae) {
            try {
                MainProgram.main(new String[0]);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
