java - 子字符串后换行

Question

如果我在 Java 中使用模式和匹配器，如何在找到子字符串后立即添加换行符？更新

我找到了使用 replaceAll(String,String); 方法的解决方案

非常感谢大家，我的解决方案已格式化如下

 String contentsToSearch = "This is an example string /* example comment in my string */ with some extra text following my inline comment";
//String regex = "[*/]" ;
//Pattern pattern = Pattern.compile(regex);
//Matcher matcher = pattern.matcher(contentsToSearch);

//if(matcher.find()){
      // add a line break to the string i am searching
 //}else{
      // print out my string regularly
  //    System.out.println(contentsToSearch);
 //}
 contentsToSearch = contentsToSearch.replaceAll("\\*/", "\\*/\n");
 System.out.println(contentsToSearch);

你可以简单地这样做:

contentsToSearch = contentsToSearch.replaceAll("(/\\*|\\*/)", "$1\n")
