如何在Java中使用多个定界符分隔字符串并且没有空白？

Question

how can i separate a string like this in java? Quotes are not seperate. The following code is entirely a string along with println. And i need to separate it into tokens as in the output.

println "How are you",Sir, "Hope you are doing good","?"

Note: There are no whitespaces between you" and , and so on.. output:

println
"how are you"
,
Sir
,
"Hope you are doing good"
,
"?"

Dont know if it is optimised but it will give your desired results.

Pattern pattern = Pattern.compile("(\"[^\"]*\")|(\\w+)|(,)");
        Matcher matcher = pattern.matcher(string);
        while(matcher.find()){
            if(matcher.group(2)!=null)
            System.out.println(matcher.group(2));
            if(matcher.group(1)!=null)
            System.out.println(matcher.group(1));
            if(matcher.group(3)!=null)
            System.out.println(matcher.group(3));
        }
