无论如何，代码确实有效。它将从英语翻译成西班牙语或西班牙语翻译成英语。您需要做的就是确保您有办法 select 您想要选择哪个翻译方向。目前你没有这个并且正在通过默认的 en 翻译成 es。如果将 fromLang 变量内容更改为 "es" 并将 toLang 变量内容更改为 en 并输入西班牙语 word 到 JTextArea t1 然后点击 Translate 按钮你会将翻译接收到 Console Window（而不是 JTextArea，t2）。接收到的字符串应放入 JTextArea，t2。为了将 returned 字符串放入 JTextArea t2 中，您需要使用 tranlate() 方法 return String 类型，然后在方法底部的 while 循环中，而不是将 returned 数据发送到控制台，执行如下操作：
public static String translate(String fromLang, String toLang, String text) throws Exception {
// ... Most method code here ...
String output;
StringBuilder sb = new StringBuilder();
while ((output = br.readLine()) != null) {
sb.append(output).append(System.lineSeparator());
System.out.println(output); // Optional - For testing
}
conn.disconnect();
return sb.toString();
}
现在，在调用 translate() 方法的地方，改为这样做：
try {
String translation = translate(fromLang, toLang, text);
t2.setText(translation);
}
catch (Exception e) {
System.out.println(e);
}
现在 returned 翻译将放置在 t2 JTextArea 中。我已进行上述修改并将其应用到您提供的以下代码中：
