hi,

yes in OS command for example - cksum (program on unix)

>>>>or mapping. If so , what is the procedure to follow.

yes - you'd need a java mapping for that  - type on google - checksum java

@MIchal ,@ Baskar: Thanks a lot for your inputs. Found a java mapping program in a thread.

Easier now even to do with java mapping. Java supports checksum classes in java.util.zip package.  Please refer these two links.  Read the file data using fileinputstream instead of string and then use the checksum class and pass the bytes content of file as argument to its update method.
