java find and replace %

In java 1.8.0 I am trying to replace %, but it is not matching 

  String str = "%28Sample text%29";

  str.replaceAll("%29", "\\)");

  str.replaceAll("%28", "\\(");
  System.out.println("Replaced string is " + str);

I have tried all this Replace symbol "%" with word "Percent" Nothing worked for me. Thanks in Advance.

The problem is that you misunderstood the usage of replaceall. It's for regex based replacements. What you need to use is the normal replace method like that:

String str = "%28Sample text%29";

str=str.replace("%29", "\\)"). replace("%28", "\\(");
System.out.println("Replaced string is " + str);

Jerry06's answer is correct.

But you could do this simply by using URLDecoder to decode those unicode value.

String s = "%28Hello World!%29";
s = URLDecoder.decode(s, "UTF-8");
System.out.println(s);

Will output :

(Hello World!)

It's working. You need re-assign to str

  str = str.replaceAll("%29", "\\)");

  str = str.replaceAll("%28", "\\(");
