Question 1 public class Flat { private int noOfRooms; private double area; private boolean seaView; public Flat() { noOfRooms = 3; area = 200; seaView = true; } %3D public void setFlat(int n, double a, boolean s) { noOfRooms = n; area = a; seaView = s; } public int getNoOfRooms( ) { return noOfRooms; } public double getArea( ) { return area; } public boolean getSeaView( ) { return seaView; } } Write a static method named findFlats that takes as a parameter an array of type Flat named list. The method should count and return the number of flats that have 3 or more rooms and with a sea view. The method prototype is: public static int findFlats (Flat[] list); Note: assume the array is already declared, populated with data in the main method and ready to be used.

Part 1: Design a Class You’ll design a class named Car that has the following fields: yearModel—An Integer that holds the car’s model year make—A String that holds the make of the car speed—An Integer that holds the car’s current speed The class should have the following constructor and other methods: The constructor should accept the car’s model year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Design appropriate accessor methods to get the values stored in an object’s yearModel, make, and speed fields. The accelerate method should add 5 to the speed field each time it’s called. The brake method should subtract 5 from the speed field each time it’s called. Create your class in a plain-text editor such as Notepad or TextEdit and save as a text file (*.txt). Part 2: Design a Program You’ll create both pseudocode and a flowchart to design a program that creates a Car object…
