We want make a package of goal kilos of chocolate. We have small bars (1 kilo

each) and big bars (5 kilos each). Return the number of small bars to use, assuming

we always use big bars before small bars. Return -1 if it can't be done.

makeChocolate(4, 1, 9) → 4

makeChocolate(4, 1, 10) → -1

makeChocolate(4, 1, 7) → 2

Skeleton of the method you should use to return the number:

public int makeChocolate(int small, int big, int goal) {

}

Create a class named Vehicle with instance variables make (String type), color (String type), year ( integer type) and model ( String type). All the variables have default access behaviour.  Vehicle class also contains a constructor with four parameters to initialize the make, color, year and model of a specific Vehicle object.

Vehicle class also has a method named printDetails() with return type void and default access to show the output of make, color, year and model of a specific Vehicle object. 

Create another class named Car that inherits Vehicle class. Car class has a private instance variable called bodyStyle (String type). The Car class also should have a constructor with five parameters. Now create the main class named Main. Inside the main method of the Main class create an object of Car class by calling the Car class constructor. Then call the printDetails() method using the created object. Finally also output body style of the Car object.
