Some were made in Canada others in The USA and the tax payment method is the following: COUNTRY STATUS TAX Canada New 8% Canada Old 2% USA New 24% USA Old 12% Write a program that shows the product’s name, net price, country of origin and status.using java, create a notification class that will send out an alert to users if they have been inactive for a week. The class should extend EventObject. The class EventObject should extend Object and implement Serializable.The fingerprint-based voting application can recognize users based on their fingerprint patterns. Since fingerprint authentication is unique for each person, the system can quickly identify the voters using their fingerprints. Naturally, a voter can vote for a candidate only once. The Admin adds all the names and photos of the candidates nominated for the election. The Admin then authenticates users by verifying their identity proof, and after verification, the voter is registered in the system. Furthermore, the Admin even enters the data when the election will end, after which the system will automatically delete the names and photos of the candidates and voters. The users can log in to the system via the unique user ID and password given by the Admin and then use their fingerprints to vote for their preferred candidate. Once the election is over, and the votes are counted, Both the Admin and users can view the election result using the election ID. In the capacity of a System…
