示例

以下示例展示了 java.util.regex.Matcher.toMatchResult() 方法的用法。

package com.tutorialspoint;

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

public class MatcherDemo {
   private static final String REGEX = "(.*)(\\d+)(.*)";
   private static final String INPUT = "This is a sample Text, 1234, with numbers in between.";

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

      if(matcher.find()) {
         //get the MatchResult Object 
         MatchResult result = matcher.toMatchResult();

         //Prints the offset after the last character of the subsequence captured by the given group during this match.
         System.out.println("Second Capturing Group - Match String - end(1): "+result.end(1));         
      }
   }
}

讓我們編譯並執行上述程式，將產生以下結果 −

Second Capturing Group - Match String - end(1): 26
