示例

以下示例显示了 Unicode 字符类匹配的用法。

package com.tutorialspoint;

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());
      }
   }
}

让我们来编译和运行以上程序，它将产生以下结果 −

Match String start(): 9
