Java做一个进制转换小工具

通过swing和awt实现的一个简单的进制转换工具 可以进行数之间的进制转换 只有两个类 所有代码都放在github/13337356453/BHD_Converter 可自行下载 因为某些特殊的原因，没有把窗口弄得更漂亮（因为懒）

代码如下 BHD_Converter.Java

package main; import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import dialog.TextDialog; public class BHD_Converter extends JFrame{ private final String title="进制转换"; private final int[] size=new int[]{300,400}; private final String[] radix=new String[]{"二进制","八进制","十进制","十六进制"}; private Container c=getContentPane(); private JLabel label=new JLabel("进制转换"); private JComboBox<String> fromBox=new JComboBox<>(radix); private JComboBox<String> toBox=new JComboBox<>(radix); private JLabel inputLabel=new JLabel("Input"); private JLabel outputLabel=new JLabel("Output"); private JTextField inputField=new JTextField(); private JTextField outputField=new JTextField(); private JButton startButton=new JButton("Start"); private JPanel panel1=new JPanel(); private JPanel panel2=new JPanel(); private JPanel panel3=new JPanel(); private JPanel panel4=new JPanel(); public BHD_Converter(){ show_window(); button_event(); setLayout(new GridLayout(4,1)); setTitle(title); setVisible(true); setResizable(false); setSize(size[0], size[1]); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); } private void show_window(){ label.setFont(new Font("微软雅黑",Font.BOLD,30)); panel1.add(label,BorderLayout.CENTER); c.add(panel1); panel2.setLayout(null); fromBox.setBorder(BorderFactory.createTitledBorder("From")); fromBox.setFont(new Font("微软雅黑",Font.PLAIN,15)); fromBox.setBounds(0,0,140,50); toBox.setBorder(BorderFactory.createTitledBorder("To")); toBox.setFont(new Font("微软雅黑",Font.PLAIN,15)); toBox.setBounds(140,0,140,50); panel2.add(fromBox); panel2.add(toBox); c.add(panel2); panel3.setLayout(null); inputLabel.setFont(new Font("微软雅黑",Font.PLAIN,20)); inputLabel.setBounds(10,0,100,40); inputField.setFont(new Font("宋体",Font.BOLD,15)); inputField.setBounds(10,40,120,30); outputLabel.setFont(new Font("微软雅黑",Font.PLAIN,20)); outputLabel.setBounds(150,0,100,40); outputField.setFont(new Font("宋体",Font.BOLD,15)); outputField.setEditable(false); outputField.setBounds(150,40,120,30); panel3.add(inputLabel); panel3.add(outputLabel); panel3.add(inputField); panel3.add(outputField); c.add(panel3); startButton.setFocusPainted(false); startButton.setFont(new Font("微软雅黑",Font.PLAIN,20)); panel4.add(startButton,BorderLayout.CENTER); c.add(panel4); } private void button_event(){ startButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { String from=(String)fromBox.getSelectedItem(); String to=(String)toBox.getSelectedItem(); String input=inputField.getText(); String result; switch (from){ case "二进制": try { switch (to){ case "八进制": result=Integer.toOctalString(Integer.parseInt(input,2)); outputField.setText(result); break; case "十进制": result=Integer.parseInt(input,2)+""; outputField.setText(result); break; case "十六进制": result=Integer.toHexString(Integer.parseInt(input,2)); outputField.setText(result); break; default: outputField.setText(input); } } catch (NumberFormatException e1){ new TextDialog("错误","输入的不是二进制数"); inputField.setText(""); } break; case "八进制": try{ switch (to){ case "二进制": result=Integer.toBinaryString(Integer.parseInt(input,8)); outputField.setText(result); break; case "十进制": result=Integer.parseInt(input,8)+""; outputField.setText(result); break; case "十六进制": result=Integer.toHexString(Integer.parseInt(input,8)); outputField.setText(result); break; default: outputField.setText(input); } } catch (NumberFormatException e1){ new TextDialog("错误","输入的不是八进制数"); outputField.setText(""); } break; case "十进制": switch (to){ case "二进制": result=Integer.toBinaryString(Integer.valueOf(input)); outputField.setText(result); break; case "八进制": result=Integer.toOctalString(Integer.valueOf(input)); outputField.setText(result); break; case "十六进制": result=Integer.toHexString(Integer.valueOf(input)); outputField.setText(result); break; default: outputField.setText(input); } break; case "十六进制": try{ switch (to){ case "二进制": result=Integer.toBinaryString(Integer.parseInt(input,16)); outputField.setText(result); break; case "八进制": result=Integer.toOctalString(Integer.parseInt(input,16)); outputField.setText(result); break; case "十进制": result=Integer.parseInt(input,16)+""; outputField.setText(result); break; default: outputField.setText(input); } } catch (NumberFormatException e1){ new TextDialog("错误","输入的不是十六进制数"); outputField.setText(""); } } } }); } public static void main(String[] args) { new BHD_Converter(); } }

TextDialog.java

package dialog; import javax.swing.*; import java.awt.*; public class TextDialog extends JDialog { public TextDialog(String title,String text) { // TODO 自动生成的构造函数存根 Container c=getContentPane(); c.add(new JLabel(text),SwingConstants.CENTER); setTitle(title); setSize(100, 100); setVisible(true); } }
