The animal classthis class represents a an animal residing at a zoo. it has a weight (in pounds),height (in inches), a name, and a color. the methods in the class include constructors,getters, and a tostring. you will finish the implementation of these methods. referto the code documentation.1.getters: you will need to implement getter methods. these get a value (froma member variable) in the animal class. you will make a getter method toreturn each variable (weight, height, name, color). reference getname if youare having issues.2.tostring: you will need to finish the tostring method. this returns a stringcontaining information about an animal. the output string should be of theformat: ” (name) , a ( color )â’colored animal .

Consider how gaming consoles initially relied on joysticks and joypads and then made the switch to modern gaming controls, which include analog sticks, buttons and switches, touch controls, accelerometers, motion controls, etc. name at least two kinds of gaming experiences that are possible with these new control devices but were not possible on original joysticks. explain how new technologies made this newer game style possible.

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.
