String parser logic in java

Question

I have a string like below which can grow further with few more AND/OR/NOT condition but maintains the syntax.

String string = "apple,mango,name(
        AND(
              OR(
                  gender[male,female],
                  county[USA,India]
              ),
             language[spanish,english],
             education[masters,bachelors],
             NOT(
                 education[Phd]
             )
        )
     ),orange"

Need to parse this string. partially successful to convert this string as JSON object. But couldn't do it completely.

Think about using JSON or other data formats if possible. Try not to reinvent the wheel. Can you change the input data? What are your efforts so far? — Benjamin Marwell, Aug 20 '15 at 04:40
@Ben, I was having difficulties to parse itself. With the hint of JSON, which seems to be easy. Will post the complete code once am done — Rohith Gowda, Aug 20 '15 at 19:31

You can easliy convert this to a rough json string. A quick sample would be

String json = "{"+string.replace("(",":{").replace("[",":[").replace(")","}")+"}";

Of course you would need to add to this to make it a valid json by inserting quotes as necessary " or ' .

Once you have JSOn you would be able to easily convert this to a java object. Check Jackson or GSON libraries.
