# 適用于希臘語擴展或希臘語腳本的 Java 正則表達式 > 原文： [https://howtodoinjava.com/regex/java-regex-match-any-character-in-greek-extended-or-greek-script/](https://howtodoinjava.com/regex/java-regex-match-any-character-in-greek-extended-or-greek-script/) 在本教程中，我們將學習匹配“希臘擴展” unicode 塊或希臘語腳本一部分的任何字符。 > **解決方案正則表達式：`\\p{InGreek}`和`\p{InGreekExtended}`** ## 匹配希臘文字中的任何字符 讓我們看一個示例程序，該程序能夠匹配字符串中希臘語腳本中的任何字符。 ```java  String content = "A math equation might be α + β = λ + γ";        String regex = "\\p{InGreek}"; Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE); Matcher matcher = pattern.matcher(content); while (matcher.find()) {  System.out.print("Start index: " + matcher.start());  System.out.print(" End index: " + matcher.end() + " ");  System.out.println(" : " + matcher.group()); } Output: Start index: 25 End index: 26  : α Start index: 29 End index: 30  : β Start index: 33 End index: 34  : λ Start index: 37 End index: 38  : γ ``` ## 匹配“希臘擴展” unicode 塊中的任何字符 讓我們看一個示例程序，該程序能夠匹配字符串中希臘語腳本中的任何字符。 ```java String content = "Let's learn some new greek extended characters : ? , ? etc.";        String regex = "\\p{InGreekExtended}"; Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE); Matcher matcher = pattern.matcher(content); while (matcher.find()) {  System.out.print("Start index: " + matcher.start());  System.out.print(" End index: " + matcher.end() + " ");  System.out.println(" : " + matcher.group()); } Output: Start index: 49 End index: 50  : ? Start index: 53 End index: 54  : ? ``` #### 參考： [http://en.wikipedia.org/wiki/Greek_alphabet](https://en.wikipedia.org/wiki/Greek_alphabet) [http://www.alanwood.net/unicode/greek_extended.html](http://www.alanwood.net/unicode/greek_extended.html) [https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html](https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html)
