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.
