Check if string is a grammatically valid sentence? [closed]

Question

Is there a way to check if a string represents an English sentence? I am currently looking at java packages but I cannot find anything that does it yet.

i.e.

the weather is good (valid)
the good is weather (invalid) 

Any ideas?

Thanks

What you really need is NLP parser (grammatical analysis).

This one is written in Java and it is fantastic.
