在之前寫過一個
TranslateHelper類用于在線翻譯英文單詞。
我之前寫過一個
單詞翻譯大師用于將文件中出現的所有單詞存儲在另一個文件中。存儲的格式如下：
word: explain
如：
apple: 蘋果；蘋果樹；蘋果公司
banana: 香蕉；芭蕉屬植物；喜劇演員
我們假設這里獲取單詞的原文件為D:|test_english.txt
存儲單詞的文件為D:\word_lib.txt
這次寫的TranslateHelper2類就是在此基礎上編寫的一個英漢詞典的離線版本。
在此之前我寫了一個WordFinder類用于獲取D:\word_lib.txt下的特定單詞及其解釋（沒有的話返回null）。
WordFinder.java
import java.io.BufferedReader;
import java.io.FileReader;
import java.util.StringTokenizer;
public class WordFinder {
public static String find(String word) throws Exception {
String filename = new String("D:\\word_lib.txt");
BufferedReader reader = new BufferedReader(new FileReader(filename));
String line = "";
while((line = reader.readLine()) != null) {
StringTokenizer st = new StringTokenizer(line, ":");
String key = st.nextToken();
if(key.equals(word)) {
return st.nextToken();
}
}
return null;
}
public static void main(String[] args) throws Exception {
String ans = find("apple");
System.out.println(ans);
}
}
下面是TranslateHelper2類，其詞庫是基于文件D:\word_lib.txt的，如下：
新增了一個按鍵可在線更新詞庫,即D:\word_lib.txt里面的內容（在現實點按鍵可更新）。
TranslateHelper2.java
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;
public class TranslateHelper2 extends JFrame {
private static final int Width = 500;
private static final int Height = 220;
private static JFrame frame = null;
private static FlowLayout flowLayout = null;
private static JLabel label = null;
private static JTextField wordText = null;
private static JTextField explainText = null;
private static JButton button = null;
private static JButton new_button = null;
public TranslateHelper2() {
frame = new JFrame("Translate Helper");
flowLayout = new FlowLayout(FlowLayout.CENTER);
flowLayout.setHgap(20);
flowLayout.setVgap(30);
frame.setLayout(flowLayout);
label = new JLabel("單詞：");
wordText = new JTextField(10);
explainText = new JTextField(40);
button = new JButton("提交");
new_button = new JButton("在線時點擊可更新");
frame.add(label);
frame.add(wordText);
frame.add(button);
frame.add(explainText);
frame.add(new_button);
button.addActionListener(new ButtonAction());
new_button.addActionListener(new ButtonAction());
frame.setVisible(true);
frame.setSize(Width, Height);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
private class ButtonAction implements ActionListener {
public void actionPerformed(ActionEvent evt) {
Object s = evt.getSource();
//System.out.println("hello");
if(s == button) {
String word = wordText.getText();
try {
String _word = word;
String _explain = WordFinder.find(word);
wordText.setText(_word);
explainText.setText(_explain);
} catch (Exception e) {
e.printStackTrace();
}
} else if(s == new_button) {
try {
TranslateMaster.translateAllLocal("D:\\test_english.txt", "D:\\word_lib.txt");
} catch (Exception e) {
return;
}
}
}
}
public static void main(String[] args) {
new TranslateHelper2();
}
}
