java - 如何将二进制文件存储到数组中并将其放入不同的标签(编译程序)？

Question

所以我有一个编译程序，但我有两个小问题。该程序将十六进制转换为十进制和二进制，并将其显示在这个可爱的小 GUI 中。

问题:

我想将二进制文件放入一个数组中，然后在连续的 5 个小框窗口之间传输。转换代码在那里，但我不知道如何拆分它。

这是我的司机:

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


public class HBDconverter {


    public static void main(String[] args) {
    JFrame frame = new JFrame ("Hexadecimal to Binary and Decimal #suchamaze");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);   
    frame.getContentPane().add(new HBDconverterpanel());
    frame.pack();
    frame.setVisible(true);

    }
}

这里是所有更有趣的代码:

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

public class HBDconverterpanel extends JPanel {


     private JTextField hexString = new JTextField();
     private JLabel decimalNumber = new JLabel();
     private JLabel binaryNumber = new JLabel();


                public HBDconverterpanel() {

              JLabel programname = new JLabel("HBD Converter");
                 setLayout(new BorderLayout());
                 setPreferredSize(new Dimension(400, 150));
                 setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));

                 hexString.addActionListener(new ActionListener() {


               public void actionPerformed(ActionEvent e) {
                        converttehInput();
                                                             }  
                                                            });

              JPanel panelName = new JPanel(new GridLayout(1, 2));
              panelName.add(programname);
              panelName.add(hexString);
              add(panelName, BorderLayout.NORTH);

              JPanel binaryPanel = new JPanel(new GridLayout(1, 6));
              binaryPanel.add(new JLabel("Binary"));
                  binaryPanel.add(binaryNumber);
              add(binaryPanel, BorderLayout.CENTER);

            JPanel decimalPanel = new JPanel(new GridLayout(1, 3));
            decimalPanel.add(new JLabel("Decimal"));
            decimalPanel.add(decimalNumber);
            add(decimalPanel, BorderLayout.SOUTH);

    }
//This take the integer Input (really hex) and converts for the GUIs above
                       private void converttehInput() {
 //wow
                         {
                             Integer input = Integer.valueOf(hexString.getText(), 16);
                             decimalNumber.setText(String.valueOf(input));
                             binaryNumber.setText(Integer.toBinaryString(input));
                        }    

 }
    }

似乎你拥有的比你预期的要多。
我猜你使用了一些代码生成器/GUI 生成器，
你没有检查它为你生成了什么。
您应该检查并清理不需要的内容。

          binaryLabel = new JLabel ("-");
        binaryLabel2 = new JLabel("-");
        binaryLabel3 = new JLabel("-");
        binaryLabel4 = new JLabel("-");
        binaryLabel5 = new JLabel("-");    
        binaryPanel.add(binaryLabel);
        binaryPanel.add(binaryLabel2);
        binaryPanel.add(binaryLabel3);
        binaryPanel.add(binaryLabel4);
        binaryPanel.add(binaryLabel5);
        binaryPanel.add(binaryLabel5);

试试这个。

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

    public class HBDconverterpanel extends JPanel {

        private JTextField hexString = new JTextField();
        private JLabel decimalLabel, binaryLabel;
        private JLabel decimalNumber = new JLabel();
        private JLabel binaryNumber = new JLabel();

        public HBDconverterpanel() {

            JLabel programname = new JLabel("HBD Converter");
            setLayout(new BorderLayout());
            setPreferredSize(new Dimension(400, 150));
            setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));

            hexString.addActionListener(new ActionListener() {

                public void actionPerformed(ActionEvent e) {
                    converttehInput();
                }
            });

            JPanel panelName = new JPanel(new GridLayout(1, 2));
            panelName.add(programname);
            panelName.add(hexString);
            add(panelName, BorderLayout.NORTH);

            JPanel binaryPanel = new JPanel(new GridLayout(1, 6));
            binaryPanel.add(new JLabel("Binary"));
            binaryLabel = new JLabel("-");
            binaryPanel.add(binaryLabel);
            binaryPanel.add(binaryNumber);
            add(binaryPanel, BorderLayout.CENTER);

            JPanel decimalPanel = new JPanel(new GridLayout(1, 3));
            decimalPanel.add(new JLabel("Decimal"));
            decimalLabel = new JLabel("-");
            decimalPanel.add(decimalLabel);
            decimalPanel.add(decimalNumber);
            add(decimalPanel, BorderLayout.SOUTH);

        }

        // This take the integer Input (really hex) and converts for the GUIs above
        private void converttehInput() {
            // wow
            {
                Integer input = Integer.valueOf(hexString.getText(), 16);
                decimalNumber.setText(String.valueOf(input));
                binaryNumber.setText(Integer.toBinaryString(input));
            }

        }
    }

你应该得到这个。
