UndergraduateStudent: The calculateFinalGrade method takes $3$ doubles, each of which will be an exam grade out

of $100.$ Each exam is worth $33\%$ of their final grade. This method sets the finalGrade attribute, which is the average

of the three test grades.

GraduateStudent: The calculateFinalGrade method takes $3$ doubles, each of which will be an exam grade out of

$100.$ The first two exams are worth $25\%$ of the final grade, and the third exam is worth $50\%$ of the final grade. This

method sets the finalGrade attribute, which is the average of the three test grades.

Player: The attack method returns a double value that is a result of the following calculation: strength $*$ dexterity $+$

$($intelligence $/2).$ The defend method returns a double that is the result of the following calculation: strength $*$

dexterity $+($strength $/2)$

Archer: The shootArrow method accepts no parameters but instead calls the attack method is then multiplied by the

rangedDamage and the result is returned as a double.

Barbarian: The shieldBash method accepts no parameters but instead calls the attack method is then multiplied by

the shieldDamage and the result is returned as a double.

Rogue: The backstab method accepts no parameters but instead calls the attack method is then multiplied by the

stabStrength and the result is returned as a double.

Warlock: The arcaneFire method accepts no parameters but instead calls the attack method is then multiplied by the

magicDamage and the result is returned as a double.

SpaceCraft: The unloadCargo method displays all items in the cargohold and then removes them. The loadCargo

method accepts a String as a parameter and adds it to the cargohold if there is space. The setCargoholdSize

method sets the size of the cargohold and also initializes the array. If the array has not been initialized when another

method is called you should default the cargohold to size $10.$

SpaceFighter: The weaponsGrid should be initialized in the default constructor to size $10.$ The addWeapon method

should accept a String as a parameter and add that string to the weaponsGrid if there is space. If there is no space

print a message that says $$Cannot add weapon. Grid is currently full.$$ The removeWeapon method should accept a

string and remove that weapon from the weapons grid. If the weapon does not exist within the grid print a message

that says $$Weapon cannot be found and cannot be removed$$

SpaceTanker: The addFuel method accepts a String and an integer as parameters. The String determines which

type of fuel is being added and the int determines how much fuel. The fuel stored at index $0$ is hydrogen, index $1$ is

ethanol, $2$ is ammonia, and $3$ is plasma. No other types of fuel can be stored. The dumpFuel method removes all of

the stored fuel and sets the array values to $0.$

SpaceTransporter: The sortCargohold method will sort all items in the cargohold in alphabetical order $($A$-$Z$)$ ignoring

capitalization. You must use an insertion sort to complete this task. The searchCargohold method will accept a

String as a parameter and return in integer that is the location of the item you are searching for. If no item is found,

return $-1.$

SpaceDrill: The operateDrill method will accept no parameters but will return a String of the type of item drilled. This

item type will be determined by the maximum depth this drill can operate at$.$ If the maximum depth is less than $50$ it

will return coal, less than $100$ will return iron, less than $200$ will return titanium, and greater than $200$ will return

palladium.

SpaceCarrier: The loadShip method will accept a String as a parameter and will add that string $($ship name$)$ to the

loadingDock. The unloadShip method will accept a String and will remove that ship from the loadingDock. Both of

these methods will return a Boolean that will indicate whether or not the action was completed successfully. The

loadingDock should be initialized in your default constructor to the size of $10.$

Triangle: If any of the three angles entered are $90$ degrees exactly, set the isRightTriangle boolean to true within

your mutators for the angles. If the sum of the three angles are not $180$ degrees you should set the isValid boolean

to false, otherwise it should be true. The calculateArea method should calculate the area of a valid triangle. The

calculatePerimeter method should calculate the perimeter of a valid triangle.

Circle: The calculateArea method should calculate the area of a valid circle. The calculatePerimeter method should

calculate the perimeter of a valid circle. If no radius has been set, default the value to $1.$

Rectangle: The calculateArea method should calculate the area of a valid rectangle. The calculatePerimeter method

should calculate the perimeter of a valid rectangle. If the rectangle is a square you should set the isSquare attribute

to true.

Pet: The speak method should return a string that says $$Buzzz$$;

Dog: The speak method should return a String that is a variation of the w
