Given the following UML diagram for class Chair:$$

$$ Please do the following:$1-$ Create a class file called Chair.java that implements the UML displayed above exactly as specified $($same variable names, types, $).$ Also, make sure that the no$-$arg constructor calls the all$-$argument constructor and provides default values for the properties.$2-$ Create a class file called Room.java that implements a class called Room that has the following properties and constructors$/$methods:$$Properties $($All Private$)$: number $($int$),$ length $($double$),$ width $($double$),$ array of type Chair called chairs.$$all$-$argument constructor that initializes all Room propertiessetter$/$getter methods for each of the properties abovemethod displayRoomInfo$()$ which prints a rooms number, length, width, and total number of chairs in a room, as well as the number of chairs of each color $($red$,$ yellow, or white$).$You should also create a UML diagram for this class as described below.$3-$ Create a class file called Driver.java that implements the Driver class which should implement the following two methods:$$main method which should create an array of room objects called rooms $($For this program, set the size of the array to exactly $3).$ To initialize the property values for each room in array rooms, you should do the following:$$a$-$ Create an array of chairs with a random number of chairs between $20$ and $50($inclusive$)$ and add that number of Chair objects to the array.$$ Each Chair object added to the array should be given the same default value for properties weight and dateManufactured.$$ As for property distanceFromFrontWall, each chair should be given a random value that does not exceed the length of the room.$$ For the property color, you should assign a random color out of the following three colors only $($ red, yellow, or white$).$ Use the Random class to do those.b$-$ Use the all$-$argument Room constructor to set a number for each room$($ Use $201,202,203$ sequentially in this case$),$ a random number from $30\mathrm{.}0$ to $50\mathrm{.}0$ for room length, and a random number from $20\mathrm{.}0$ to $30\mathrm{.}0$ for room width. Use the Random class.$$ Also set the room chairs using the array created in point a$-$ above.$$displayRooms method which takes an array of type Room as an argument and loops through it displaying the property values for each room in the array $($you should call the method displayRoomInfo$()$ to do that$).$ The table should be organized as follows:number$$ length$$ width$$ total chairs$$ red$$ yellow$$ whitee.g$.$:$20145\mathrm{.}3425\mathrm{.}2042121911$Your Driver class should define a constant called SEEDVALUE which is the value of the seed to be used when you create your object of Random Type to be used in all your program.$$ You should use the same created Random object $($ONE OBJECT ONLY$)$ with the same seed $($SEEDVALE$)$ to generate all the random values described above $($using the suitable methods in the Random class$).$ NOT doing this step correctly will cause you to lose many points.
