how can i escape a group of special characters in java in one method?

Use regular expression to replace those characters in one go.

example:

 String s="some text && || []!{} ()^*?~ and ";
        Pattern p= Pattern.compile("([-&\\|!\\(\\){}\\[\\]\\^\"\\~\\*\\?:\\\\])");

        s=p.matcher(s).replaceAll("\\\\$1");
        System.out.println(s);\\prints some text \&\& \|\| \[\]\!\{\} \(\)\^\*\?\~ and 

There is also a method called QueryParser#escape, which may be useful:

Returns a String where those characters that QueryParser expects to be escaped are escaped by a preceding \.
