ExerciseThis week we will be practicing with writing and managing multiple classes, including a designated driverclass.Getting Started To start this exercise, you should:$1.$ Open eclipse and start a new Java project named Lab$012.$ Add a Class $($named SMouse$)$ to this project, and copy the contents of the SMouse file providedinto it$\mathrm{.}3.$ Add a Class $($named SMouseDriver$)$ to this project, and copy the contents of the SMouseDriverfile provided into itRequirementsSMouse A simplified version of the books mouse class that is incomplete. You must do the following tofinish the class:$1.$ Write the body of the display instance method, so that it displays both the age and weight$($in some reasonable format$)$ of the specific mouse whos display method is invoked$\mathrm{.}2.$ Remember with in an instance method, this is an available instance variable that refers to thespecific object whos method is being invoked$\mathrm{.}3.$ Look for and fix any compilation errors$\mathrm{.}4.$ Remember that you can not run this class, there is no main method.SMouseDriver A simple driver class to test your mouse class, that is also incomplete. You must do thefollowing to finish the class:$1.$ Declare a variable that will hold the age of Mighty Mouse, prompt for this age and read it in toyour variable$\mathrm{.}2.$ grow Mighty Mouse this number of times$\mathrm{.}3.$ display Mighty Mouses new age and weight$\mathrm{.}4.$ Declare a variable that will hold the age of Mickey Mouse, prompt for this age and read it in toyour variable$\mathrm{.}5.$ grow Mickey Mouse this number of times$\mathrm{.}6.$ display Mickey Mouses new age and weight$\mathrm{.}7.$ Look for and fix any compilation errors$\mathrm{.}8.$ Run your driver class and check the output and make sure it is correct.
