We have to look at the pattern of these strings,

is it always in the form of "digit, 'abc', digit"?

Assume there is no space in 'abc', you can split the "myStr" string into

"5", "this,that", "8",

using the following code:

        String myStr = "5,\'this,that\',8";

        //spilt the string using "'", as you want to get rid of it
        String parts[] = myStr.split("'");

        //for output
        StringBuffer output = new StringBuffer();

        for (int i = 0; i < parts.length; i++) {
                //replace ',' for space to trim
                parts[i] = parts[i].replace(',', ' ').trim();

                //replace back
                parts[i] = parts[i].replace(' ', ',');

                //for output
                output.append('\"');
                output.append(parts[i]);
                output.append("\", ");
        }
        //output
        System.out.println(output.toString());
