String parsing

For example the string : iloveAVdata [221] xxdata [ab] -> iloveAV221xxab. Both the string all the data [*] -> *, seeking ideas
------ Solution ---------------------- ----------------------
regular expressions , replaceAll
I love AV data?
------ Solution - -------------------------------------------

		String str = "youloveAVdata[221]xxdata[ab]";
  		str = str.replaceAll("\\[(.+?)\\]", "$1");
  		System.out.println(str);

< br> ------ For reference only ---------------------------------------

  
  String str = "youloveAVdata[221]xxdata[ab]";
  str = str.replaceAll("data\\[(.?)\\]", "$1");
  System.out.println(str);
  
  

positive solution , a little less "data", it may be data [], I did not mention
------ For reference only ------------ ---------------------------

+1
------ For reference only - -------------------------------------
bright ,
- ---- For reference only ---------------------------------------
< br />

  String str = "youloveAVdata[221]xxdata[ab]";
  //+改成*
  str = str.replaceAll("\\[(.*?)\\]", "$1");
  System.out.println(str);
  

------ For reference only ----------------------------------- ----
replaceAll ("data [", ""); replaceAll ("]", ""); so what is the problem you
