Question

我正在编写一个加密程序，让用户输入一条消息并将其编码为矩阵，或者解码一组矩阵。我已经完成了核心，并决定它将作为一系列JFrame弹出窗口更加用户友好。我讨厌程序的最后一个问题，那就是解码方法。它应该工作的方式是，用户输入构成编码消息的矩阵的数量，并且用户输入在一组3个输入中循环很多次，以便通过矩阵解码消息矩阵。我遇到的问题是我有点迷失在如何循环我的用户输入JFrame，就像我用我的示例代码。这是用户输入多少矩阵的JFrame：

package matrix_with_GUI;
import javax.swing.* ;

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

public class DecodeMenu2 extends JFrame implements ActionListener{
private JButton action1 = new JButton ("");
private JPanel pane = new JPanel();
private JLabel lbl;
private TextField slot1 = new TextField(2);
private double[][] junk = new double[3][3];
private String message = "";

public void DecodeMenu2(double[][] code){
    junk = code;
    JPanel pane=new JPanel();
    setTitle ("Start Menu") ;
    JFrame frame = new JFrame("");

    setVisible(true);
    setSize (600, 150) ;
    setLocationRelativeTo (null) ;
    frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE) ;

    action1 = new JButton("Continue");
    lbl = new JLabel ("          How Many Matrices make up your coded message? (Every set of numbers in brackets is 1 matrix)          ");
    setLayout(new FlowLayout());

    add (lbl) ;
    add(slot1);
    add(action1, BorderLayout.CENTER);
    action1.addActionListener (this);
}

@Override
public void actionPerformed(ActionEvent e) {
    int size = Integer.parseInt(slot1.getText());
    DecodeCore x = new DecodeCore();
    for(int count = size; count > 0; count--){
        x.DecodeCore(junk);
        message += x.getMessage();
    }
    DecodePrint y = new DecodePrint();
    y.DecodePrint(message);
    this.dispose();
}

}

以下是每次单击“继续”按钮时应循环的代码，直到达到“大小”：

package matrix_with_GUI;
import javax.swing.* ;

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

public class DecodeCore extends JFrame implements ActionListener{

private JButton action1 = new JButton ("");
private JPanel pane = new JPanel();
private JLabel lbl;
private TextField slot1 = new TextField(5);
private TextField slot2 = new TextField(5);
private TextField slot3 = new TextField(5);
private String message = "";
private double[][] inverseCode = new double[3][3];

public void DecodeCore(double[][] code){
    inverseCode = code;
    JPanel pane=new JPanel();
    setTitle ("Start Menu") ;
    JFrame frame = new JFrame("");

    setVisible(true);
    setSize (380, 150) ;
    setLocationRelativeTo (null) ;
    frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE) ;

    action1 = new JButton("Continue");
    lbl = new JLabel ("          Begin entering your Coded Message, one  matrix at a time.          ");
    setLayout(new FlowLayout());

    add (lbl) ; 
    add(slot1);
    add(slot2);
    add(slot3);
    add(action1, BorderLayout.CENTER);
    action1.addActionListener (this);
}

@Override
public void actionPerformed(ActionEvent e) {
    int sum = 0, count = 0;
    int[] matrix = new int[3];
    int[] entry = new int[3];

    entry[0] = Integer.parseInt(slot1.getText());
    entry[1] = Integer.parseInt(slot2.getText());
    entry[3] = Integer.parseInt(slot3.getText());

    for (int col = 0 ; col < 3 ; col++ ){   
        for (int row = 0 ; row < 3 ; row++ ){
            sum +=  entry[row]*inverseCode[row][col];
        }
        matrix[col] = sum;
        sum = 0;
    }
    while(count < 3){
        matrix[count] = Math.round(matrix[count] + 32);
        message += Character.toString((char) matrix[count]);
        count++;
    }
    count = 0;
}

public String getMessage(){
    return message;
}
}

很抱歉这篇长篇文章。
