无法解析JAVA中的正则表达式

Question

This is my code,

String xyz = "{\"status\":\"ok\",\"data\":[{\"RatingCount\":4}],         [{\"RatingCount\":1}], [{\"RatingCount\":1}]\"code\":1}";
    String pattern = ".*],\\s*\\[.*";//"(.*)(],\\s.*\\[)(.*)";
    Pattern p1 = Pattern.compile(pattern);
    Matcher m1 = p1.matcher(xyz);
    boolean b = m1.matches();
    System.out.println(b);

I would like to replace pattern '], [' with "" .

I used replaceAll but no luck

Answer 1

Check it in working Fiddle

Use the regex as below

String pattern = "\],[ ]*\[";

Answer 2

xyz =xyz.replaceAll("]\\s*,\\s*\\[", "],[");

This worked like charm and also this link helped me alot http://regexr.com/

Thank you for all your inputs!

Answer 3

The output of this block is: {"status":"ok","data":[{"RatingCount":4}{"RatingCount":1}{"RatingCount":1}]"code":1}

public static void main(String[] args) {
    String str = "{\"status\":\"ok\",\"data\":[{\"RatingCount\":4}],         [{\"RatingCount\":1}], [{\"RatingCount\":1}]\"code\":1}";
    System.out.println(replace(str, "\\],\\s+\\["));
  }

  public static String replace(String str, String regex) {
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(str);
    return matcher.replaceAll("");
  }
