下面的示例显示java.time.Matcher.quoteReplacement(String s)方法的用法。
package com.learnfk; import java.util.regex.Matcher; import java.util.regex.Pattern; public class MatcherDemo { private static String REGEX="dog"; private static String INPUT="The dog says meow " + "All dogs say meow."; private static String REPLACE="cat$"; public static void main(String[] args) { Pattern pattern=Pattern.compile(REGEX); //获取匹配器对象 Matcher matcher=pattern.matcher(INPUT); try{ //下面的行将抛出异常 INPUT=matcher.replaceAll(REPLACE); } catch(Exception e){ System.out.println("Exception: "+ e.getMessage()); } INPUT=matcher.replaceAll(matcher.quoteReplacement(REPLACE)); System.out.println(INPUT); } }
让无涯教程编译并运行以上程序,这将产生以下结果-
Exception: Illegal group reference: group index is missing The cat$says meow All cat$s say meow.
