I'm not getting how to use that and implement it. Please help me to improve my code

Answer 1

put all nodes ip like below nodes=192.1.1.1,192.2.2.2

In java Resource interface is there by using that you can get your properties file

Like ResourceBundle resource=ResourceBundle.getBundle("cassandra")

then by getProperty method you can get nodes and split it by comma(,) so it will gives you Array of String mean all IP . Like nodes=resource.getString("nodes")

then in method addContactPoints() just give nodes variable .

Like addContactPoints(nodes)
