Question

I want to take user input in the console such as “keyword1 and keyword2” or “keyword1 and (keyword2 or keyword3)”

Then I want to interpret that and convert it into booleans to query the keyword in an array.

It would have to handle “and”,”or” and “()” brackets.

I would rather not use a third-party library for it but if there is no easy way I’ll take that. I started looking into Lucene but it seems complex for my needs and I want to be able to query an array instead of a document.

Edit: Note I am rather new to programming so simpler solutions are preferred.

Answer 1

You need a parser, but you could consider using the java compiler itself if you wrapped the input in code that would make a valid class.
