JAVA2 Assignment 1 | Write a class called Room, which has three private instance variables ..

Write a class called Room, which has three private instance variables: - a double width, representing the width of the room in feet, - a double length, representing the length of the room in feet, and - an int floor, representing the building floor that the room is on. a) Write a default constructor for the class Room that sets the width to 10, the length to 12.5, and the floor to 1. 1 mark b)Write get and set methods ("getters" and "setters") for the three instance variables. For the set methods for the width and length, only positive values should be set. If the input is 0 or a negative number, the variables should not be changed.1.5 mark c) Write a constructor for the class Room that takes in two double parameters and an int, and sets length to the larger double, width to the smaller double, and floor to the int. Use the setters from part (b). 1.5 mark d) toString method for the class Room, so that it a String with the form "length x width on floor floor". For example, calling toString on the instance of Room created by the default constructor from part (a) would return the String "12.5 x 10, floor 1". lmark
2)The Java class called Song is started below. An object of class Song is a piece of music.
