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.
