Hetal,
What would it mean to have a size for an Integer? The number of digits?

The database stores an integer as data (bytes.) You could calculate the number of digits in a value (or in max int) yourself though.

Hetal,

try

int size = resulset.getMetaData().getPrecision(1);
 
It is sorta covered in the JavaRanch Style Guide.
