java connect mysql error

Source code is very simple to connect , no errors. There should be a driver problem

ERROR: index path not specified

Usage: java org.apache.lucene.index.CheckIndex pathToIndex [-fix] [-segment X] [-segment Y]

-fix: actually write a new segments_N file, removing any problematic segments

-segment X:. only check the specified segments This can be specified multiple

times, to check more than one segment, eg '-segment _2-segment _a'.

You can't use this with the-fix option

** WARNING **:-fix should only be used on an emergency basis as it will cause

documents (perhaps many) to be permanently removed from the index. Always make

a backup copy of your index before running this! Do not run this tool on an index

that is actively being written to. You have been warned!

Run without-fix, this tool will open the index, report version information

and report any exceptions it hits and what action it would take if-fix were

specified. With-fix, this tool will remove any segments that have issues and

write a new segments_N file. This means all documents contained in the affected

segments will be removed.

This tool exits with exit code 1 if the index cannot be opened or has any

corruption, else 0.
why this error Index not found ?
