Here is a simple Java program using Swing for GUI and Google Translate API for translation:
```
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.JSONObject;
public class Translator extends JFrame {
private JTextArea textArea;
private JComboBox<String> languageComboBox;
private JButton translateButton;
public Translator() {
setLayout(new BorderLayout());
// Text Area
textArea = new JTextArea(20, 40);
add(new JScrollPane(textArea), BorderLayout.CENTER);
// Language Combo Box
String[] languages = {"English", "Spanish", "French", "German", "Italian", "Portuguese", "Chinese", "Japanese", "Korean"};
languageComboBox = new JComboBox<>(languages);
add(languageComboBox, BorderLayout.NORTH);
// Translate Button
translateButton = new JButton("Translate");
translateButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
translateText();
}
});
add(translateButton, BorderLayout.SOUTH);
setSize(600, 400);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
}
private void translateText() {
String text = textArea.getText();
String language = (String) languageComboBox.getSelectedItem();
String translatedText = translate(text, language);
textArea.setText(translatedText);
}
private String translate(String text, String language) {
try {
URL url = new URL("https://translation.googleapis.com/language/translate/v2?key=YOUR_API_KEY");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
JSONObject json = new JSONObject();
json.put("q", text);
json.put("target", getLanguageCode(language));
connection.setDoOutput(true);
connection.getOutputStream().write(json.toString().getBytes());
int responseCode = connection.getResponseCode();
if (responseCode == 200) {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
JSONObject jsonResponse = new JSONObject(response.toString());
return jsonResponse.getJSONArray("data").getJSONObject(0).getString("translations").getJSONObject(0).getString("translatedText");
} else {
return "Error: " + responseCode;
}
} catch (Exception e) {
return "Error: " + e.getMessage();
}
}
private String getLanguageCode(String language) {
switch (language) {
case "English":
return "en";
case "Spanish":
return "es";
case "French":
return "fr";
case "German":
return "de";
case "Italian":
return "it";
case "Portuguese":
return "pt";
case "Chinese":
return "zh-CN";
case "Japanese":
return "ja";
case "Korean":
return "ko";
default:
return "en";
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new Translator();
}
});
}
}
```
Replace `YOUR_API_KEY` with your actual Google Translate API key.
Note:
- This program uses the Google Translate API, which requires a API key.
- The program translates the text in the text area to the selected language.
- The program uses the `getLanguageCode` method to get the language
code for the selected language.
- The program uses the `translate` method to translate the text using the Google Translate API.
