Question

I want to get rid of all symbols or punctuation marks in a string for example String str = "\"hello!.?,\""; the output of str should be: hello

You can use String's replaceAll.

String str = "\"hello!.?,\"";
String newStr = str.replaceAll("[^\\w]", "");
System.out.println(newStr);

For more details on how to construct a regex, see the documentation of Pattern.
