java parser

P: 2
Hello everybody :)
I've got a question. I want to know how can I write a parser
"There is a table(dimension: 3 in 4 in 5 meters) in the room"
in a way that the output would be this:
Type: table
Numbers: 1
Size: 60 M^3
Position: Room

I tried substring and split method, but I didn't get the result that I wanted. Could you please help me with this? :( What are the useful methods with which I can write this code?

Use regular expression.

But the better way: define an EBNF-like grammar and then use some ready-made method that converts them into a tree of tokens.
Look in Wikipedia, "Recursive descent parser" for an example.
