OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

(d) When constructing an object from a subclass, its superclass’s initializer is automatically invoked.Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. Create a public class named Monday. This class shall contain the main method. 2. Define an interface (without a modifier) named Alarm. This interface shall contain two (2) void methods named setAlarm() and showAlarm(). The setAlarm() method has a String parameter named time. 3. Add two (2) classes without modifiers named Weekday (abstract) and Monday. 4. For the Weekday class, implement the Alarm interface. Leave this class empty. 5. Set Weekday as the parent of Monday. Import Scanner from java.util and LocalTime from java.time. For showAlarm(), add these two (2) statements: LocalTime alarm = LocalTime .parse(time); LocalTime now = LocalTime.now(); Explanation: parse() converts String to time, while now() obtains the current time. 7. The output shall ask the user to enter the time for the alarm. If the time entered is past the current time, then display "Alarm is set for tomorrow!";…
- Please code in python Create a program with two classes – the person class and the student The person class has the following properties: first name (first_name), last name (last_name) street address (address) city (city) zip code (zip) The class has the following methods: get_full_name, which returns the full name of a person get_full_address, which return greeting, returns a greeting message.
