1. The first is the Bex class that made a heavy "Bere that should be saved in a file called Bor.java. This class should include the following a. Foar private integer instance variables store the length.Width, Height, and Wright of the Box. Measurements are in feet and pounds Four public methods (setters) to set the value of each of these parameters: setlength. setWidth, settleight, and set Weight. c. Four public methods (gotters) to rctum the value of cach of these parameters: getlength, get Width, getHeight, and pet Weight Two constructor Constructor #1 (defaul constructor - has no parameters and initializes each of the Box's instance variable to 0. Constructor that receive for integer permeten dat would initialize the box object's Length, Width, Height, and Weight e. A method calculateVolume) which returns the volume formal Length"Width"Height) of the Box object as an integer A method calculateDensity) which returns the density of the Bar (formula weight/volume) as a double check for divide by A method called toString) that returns all information about a box objects a string in the form of This Bax has Length x Width -yyy, Height -m Weight - www Volume Density-ann.de 1. The second is the TestBoxes class that should be saved in a file called Text Boxes.java that contains a mail)method. This main() method should do the following hove) 2. Create two different object bones named bl.and being the second constructor (defined The parameters of box blare Length = 10, Width 5, Height =5, and Weight = 2006 The parameters of box b2 are Length - 15, Width 22. Height 16. and Weight - 1360 h. Create a third box named using the default construct Then use the set methods defined above) to assiga values for each of the above four parameters as follows
