- JAVA Data type Java assignment meaning of operator int float double and string Pick one Java polymorphic arithmetic operator and write Java code statements that demonstrate its function for ints, floats, doubles, and strings. Also, indicate what role the operator is performing in the table below.PLZ help with the following: IN JAVA Static variables are often used: (a) in arithmetic expressions (b) to communicate between objects (c) within looping structures (d) all of the aboveC++ programming Overview This is a demonstration an ability to implement inheritance, composition, and overloaded operators in a program. Pretend to be working in the IT department for a corporation and have been tasked with developing an application to manage assigning people to a team. This process involves creating a team with a name and a purpose, the assignment of people in the team, and the assignment of a person to lead the team. Use inheritance to facilitate the reuse of code and operator overloading to allow the usage of familiar operators tailored specifically to the Person, TeamMember, and Leader classes. Composition is also demonstrated in using a Team class that contains objects of the TeamMember and Leader classes. You will need to develop several classes to maintain this information:Team, Person, TeamMember, Leader, and Date. The characteristics of TeamMember and Leader are shown below: TeamMember: Leader: ID…
- Explain how composition contributes to reusability. Distinguish between IS-A and Has-A rules.Assignment Java: Program Statement: You are required to model a vehicle parking lot system. The parking lot has a facility to park cars and scooters. The parking lot contains four parking lanes-two for cars and two for scooters. Each lane can hold ten vehicles. There is an operator with a console at the East end of the parking lot. The system should be able to handle following scenarios. Arrival of a vehicle: Type of vehicle (car or scooter) and Registration No. of vehicle should be entered Program should display suitable parking slot Vehicles arrive at East end, leave from West end Departure of Car: If not western most, all cars should be moved to the west When the car is driven out, rest of the cars should be moved to the left Vehicle data should be updated Departure of Scooter: Scooters should be able to drive out at random Vehicle data should be updated Note that when desired the operator must be able to obtain information like number of vehicles, number of scooters or number…Define Declaration statements.
- Design a new class that contains a print and read function by creating a new object and calling the print and reading functions inside the case ( data structure in java)Constant Assignment • The compiler will issue an error if you try to change the value of a constant • In Java, we use the final modifier to declare a constant final int x= 69; Add x= x+10 What is the result?Explain what logical argument means.
