varargs
- Variable
Arguments
*
varargs comes with Java 5
*
varargs allows to method to accept zero or more arguments.
*
varargs is a better approach when we don't know how many
arguments will have to pass
*
*
syntax : (data_type... variableName)
*
*
Rules -
*
1. can be only one variable argument in the method
*
2. variable argument must be the last argument
