You haven't shown us how do you execute this batch. If you use Runtime.exec() then have a look at this example of capturing output: http://www.rgagnon.com/javadetails/java-0014.html

You can redirect the output of the FIND command to a dynamically named file and have it read by Java.

C:\FIND "check" d:\c.txt > yourUniqueFileName.txt

Then read the file yourUniqueFileName.text, parse and delete on the end (or not).

You can use ProcessBuilder or Process to exec() and then capture the output. More info here. You could redirect to a file and then read the file - however you're at the mercy of diskspace/permissioning issues, plus you should uniquely name your file etc.

Note that you'll need to be careful when capturing output from a spawned process. See this answer for more details.
