Java Instance data:Variable mpg for fuel efficiency (miles per gallon = mpg)Variable gas to save how many gallons of gas left in the tank Constructors:Default constructor with no parameter. Use 0 as initial values.Overloaded constructor with two parameters Methods:getMPG() & setMPG()(getGas() & setGas()toString() methoddrive() to simulate that the car is driven for certain miles. For example, v1.drive(100) means vehicle v1 is driven 100 miles. You need to calculate the gas cost and update the gas tank: gas = gas - miles/mpg. You also need to check if there is enough gas left since gas should not be negative. You need to figure out the formal parameters for the above methods. In the testing class, prompt the user for information to create two objects of the Vehicle class. Let each vehicle drive 200 miles. Print out the left gas for each vehicle. Ex: Vehicle 1 Enter the mpg: 40 Enter the gas left: 10.5 Vehicle 2 Enter the mpg: 35 Enter the gas left: 2.1 Vehicle 1…
