一、ASCII編碼查看器

直接上代碼：

import java.awt.BorderLayout; import java.awt.EventQueue; import java.awt.Font; import java.awt.GridLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener;import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; import javax.swing.UIManager; import javax.swing.border.EmptyBorder; import javax.swing.border.EtchedBorder;public class ASCIIViewer extends JFrame {private static final long serialVersionUID = -6067423561196663639L;private JPanel contentPane;private JTextField asciiTextField;private JTextField numberTextField;private JLabel label3;private JLabel label6;public static void main(String[] args) {try {UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");} catch (Throwable e) {e.printStackTrace();}EventQueue.invokeLater(new Runnable() {public void run() {try {ASCIIViewer frame = new ASCIIViewer();frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}public ASCIIViewer() {setTitle("ASCII\u7F16\u7801\u67E5\u770B\u5668");setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);setBounds(100, 100, 450, 150);contentPane = new JPanel();contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));contentPane.setLayout(new BorderLayout(0, 0));setContentPane(contentPane);JPanel panel = new JPanel();contentPane.add(panel, BorderLayout.CENTER);panel.setLayout(new GridLayout(2, 1, 5, 5));JPanel asciiPanel = new JPanel();asciiPanel.setBorder(new EtchedBorder(EtchedBorder.LOWERED, null, null));panel.add(asciiPanel);asciiPanel.setLayout(new GridLayout(1, 5, 5, 5));JLabel label1 = new JLabel("\u8F93\u5165\u5B57\u7B26\uFF1A");label1.setFont(new Font("微軟雅黑", Font.PLAIN, 16));asciiPanel.add(label1);asciiTextField = new JTextField();asciiTextField.setFont(new Font("微軟雅黑", Font.PLAIN, 16));asciiPanel.add(asciiTextField);asciiTextField.setColumns(3);JLabel label2 = new JLabel("\u8F6C\u6362\u7ED3\u679C\uFF1A");label2.setFont(new Font("微軟雅黑", Font.PLAIN, 16));asciiPanel.add(label2);label3 = new JLabel("");label3.setFont(new Font("微軟雅黑", Font.PLAIN, 16));asciiPanel.add(label3);JButton toNumberButton = new JButton("\u8F6C\u6362");toNumberButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {do_toNumberButton_actionPerformed(e);}});toNumberButton.setFont(new Font("微軟雅黑", Font.PLAIN, 16));asciiPanel.add(toNumberButton);JPanel numberPanel = new JPanel();numberPanel.setBorder(new EtchedBorder(EtchedBorder.LOWERED, null, null));panel.add(numberPanel);numberPanel.setLayout(new GridLayout(1, 5, 5, 5));JLabel label4 = new JLabel("\u8F93\u5165\u6570\u5B57\uFF1A");label4.setFont(new Font("微軟雅黑", Font.PLAIN, 16));numberPanel.add(label4);numberTextField = new JTextField();numberTextField.setFont(new Font("微軟雅黑", Font.PLAIN, 16));numberPanel.add(numberTextField);numberTextField.setColumns(3);JLabel label5 = new JLabel("\u8F6C\u6362\u7ED3\u679C\uFF1A");label5.setFont(new Font("微軟雅黑", Font.PLAIN, 16));numberPanel.add(label5);label6 = new JLabel("");label6.setFont(new Font("微軟雅黑", Font.PLAIN, 16));numberPanel.add(label6);JButton toASCIIButton = new JButton("\u8F6C\u6362");toASCIIButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {do_toASCIIButton_actionPerformed(e);}});toASCIIButton.setFont(new Font("微軟雅黑", Font.PLAIN, 16));numberPanel.add(toASCIIButton);}protected void do_toNumberButton_actionPerformed(ActionEvent e) {String ascii = asciiTextField.getText();int i = Character.codePointAt(ascii, 0);label3.setText("" + i);}protected void do_toASCIIButton_actionPerformed(ActionEvent e) {String number = numberTextField.getText();char[] a = Character.toChars(Integer.parseInt(number));label6.setText(new String(a));} } 運行效果：

二、Java中文與ASCII碼的轉換

今天在研究Java中編碼的時候，看到了Java中ascii碼的強大。寫了一個CoderUtils.java，以后會擴展它。

import java.io.File; import java.io.FileWriter; import java.io.IOException; import java.io.PrintWriter; /** * @date 2009-3-11 * @author Xing,Xiudong * @Email:xingxiuodng[at]gmail.com * @index:http://blog.csdn.net/xxd851116 */ public class CoderUtils { public static char ascii2Char(int ASCII) { return (char) ASCII; } public static int char2ASCII(char c) { return (int) c; } public static String ascii2String(int[] ASCIIs) { StringBuffer sb = new StringBuffer(); for (int i = 0; i < ASCIIs.length; i++) { sb.append((char) ascii2Char(ASCIIs[i])); } return sb.toString(); } public static String ascii2String(String ASCIIs) { String[] ASCIIss = ASCIIs.split(","); StringBuffer sb = new StringBuffer(); for (int i = 0; i < ASCIIss.length; i++) { sb.append((char) ascii2Char(Integer.parseInt(ASCIIss[i]))); } return sb.toString(); } public static int[] string2ASCII(String s) {// 字符串轉換為ASCII碼 if (s == null || "".equals(s)) { return null; } char[] chars = s.toCharArray(); int[] asciiArray = new int[chars.length]; for (int i = 0; i < chars.length; i++) { asciiArray[i] = char2ASCII(chars[i]); } return asciiArray; } public static String getIntArrayString(int[] intArray) { return getIntArrayString(intArray, ","); } public static String getIntArrayString(int[] intArray, String delimiter) { StringBuffer sb = new StringBuffer(); for (int i = 0; i < intArray.length; i++) { sb.append(intArray[i]).append(delimiter); } return sb.toString(); } public static String getASCII(int begin, int end) { StringBuffer sb = new StringBuffer(); for (int i = begin; i < end; i++) { sb.append(i).append(":").append((char) i).append("/t"); // sb.append((char) i).append("/t"); if (i % 10 == 0) { sb.append("/n"); } } return sb.toString(); } public static String getCHASCII(int begin, int end) { return getASCII(19968, 40869); } public static void showASCII(int begin, int end) { for (int i = begin; i < end; i++) { // System.out.print(i + ":" + (char) i + "/t"); System.out.print((char) i + "/t"); if (i % 10 == 0) { System.out.println(); } } } public static void showCHASCII() { showASCII(19968, 40869); } public static void showIntArray(int[] intArray) { showIntArray(intArray, ","); } public static void showIntArray(int[] intArray, String delimiter) { for (int i = 0; i < intArray.length; i++) { System.out.print(intArray[i] + delimiter); } } public static void createFile(String filePathAndName, String fileContent) throws IOException { String filePath = filePathAndName; filePath = filePath.toString(); File myFilePath = new File(filePath); if (!myFilePath.exists()) { myFilePath.createNewFile(); } FileWriter resultFile = new FileWriter(myFilePath); PrintWriter myFile = new PrintWriter(resultFile); String strContent = fileContent; myFile.println(strContent); myFile.close();resultFile.close();} public static void main(String[] args) throws IOException { String s = "好好學習！天天向上！————笑的自然 2009年3月11日"; showIntArray(string2ASCII(s), " "); System.out.println(); System.out.println(ascii2String(string2ASCII(s))); createFile("C:/Users/huiqiang/Desktop/hui/console_ch.txt", getCHASCII(0, 50000)); } } 運行結果：

Java中文與ASCII碼的互相轉換，能夠下載任何字符。如下一瞥：
