Unicode字元類\p{InGreek}

字元類\p{InGreek}匹配任何希臘語塊字元。

範例

以下範例顯示了Unicode字元類匹配的用法。

package com.yiibai;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class UnicodeCharacterClassDemo {
   private static final String REGEX = "\\p{InGreek}";
   private static final String INPUT = "[Bb12 \tc!\u03B1";

   public static void main(String[] args) {
      // create a pattern
      Pattern  pattern = Pattern.compile(REGEX);

      // get a matcher object
      Matcher matcher = pattern.matcher(INPUT); 

      while(matcher.find()) {
         //Prints the start index of the match.
         System.out.println("Match String start(): "+matcher.start());
      }
   }
}

編譯並執行上面的程式，這將產生以下結果 -

Match String start(): 9
