Java 大小写不敏感替换

  public static void replaceString(String source,String oldStr,String newStr){
          System.out.println(source);
          String result = source.replaceAll("(?i)"+oldStr , newStr); //大小写不敏感
 
          System.out.println(result);
          System.out.println(source.replaceAll(oldStr, newStr));//大小写敏感
 
     }
