JAVA实现类似有道翻译中的原文和译文相同句子高亮的功能

实现类似有道翻译中的原文和译文相同句子高亮的功能，可以使用Java中的Swing图形界面库来开发。具体实现步骤如下：

1. 设计界面，可以使用JFrame、JPanel、JTextArea、JButton等Swing控件来实现。

2. 实现翻译功能，可以使用Java中的网络编程和API调用来实现。例如使用百度翻译API来实现翻译功能。

3. 实现句子匹配和高亮功能。可以将原文和译文分别按照句子分割成数组，然后对两个数组进行比较，找到相同的句子，并将其高亮显示。可以使用Java中的正则表达式来实现句子分割和匹配。

4. 将高亮后的原文和译文显示在界面上，可以使用JTextPane或JEditorPane控件来实现高亮显示。

下面是一个简单的代码示例，可以根据实际需求进行修改和优化：

        // 添加翻译按钮和输出区域

    public void highlight(String input, String output) {
        StyledDocument doc = outputPane.getStyledDocument();

                            int start = output.indexOf(outputSentence);
                            int end = start + outputSentence.length();
                            doc.setCharacterAttributes(start, outputSentence.length(), style, true);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        }
    }

    public String MD5(String str) {
        try {
            MessageDigest md = MessageDigest.getInstance("MD5");
            byte[] bytes = md.digest(str.getBytes("UTF-8"));
            StringBuilder sb = new StringBuilder();
            for (byte b : bytes) {
                String hex = Integer.toHexString(b & 0xff);
                if (hex.length() == 1) {
                    sb.append("0");
                }
                sb.append(hex);
            }
            return sb.toString();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
    }

    public static void main(String[] args) {
        new Translation();
    }
}

这个示例代码实现了类似有道翻译中的原文和译文相同句子高亮的功能，可以输入英文文本并翻译成中文，同时高亮显示原文和译文中相同的句子。
