A) Code a statement that creates an instance of an Account class using the default constructor and stores the object that’s created in a variable named account. b) Code a statement that creates an instance of the Account class using a constructor that has two parameters named firstName and age, and store the object in a variable named account. Assume that variables with those names have already been declared and initialized so you can pass those variables to the constructor.
c) Code a statement that sets the value of the Age property of an Account object named account to the value in a variable named newAge.
d) Code a statement that will get the value of a public static field named Count that’s defined in the Account class, and store the value in a new int variable named count. Assume that you’ve already created an object from this class that’s named account.

a)

Account account = new Account();

b)

Account account = new Account(firstName, age);

c)

account.Age = newAge;

d)

int count = Account.Count;

Explanation:

a)

new is the keyword which is used to create an object.

Account is the class name.

account is the name of an object of class Account.

account object is created to access the class Account.

Account() is the constructor of Account class. This is the default constructor and it has no parameters. Constructor has the same name as class. When a account object is created, constructor Account will be invoked.

b)

Account is the class name.

account is the name of an object of class Account.

Account() is the constructor of Account class. This is the parameterized constructor and it has two parameters i.e. firstName and age. Constructor has the same name as class. When a account object is created, constructor Account will be invoked.

c)

account.Age = newAge;

Here account is the object name. The Age property to access and update the private field of the Account class is set to the variable named newAge.

d)

This int count = Account.Count; statement gets the value of a public static field named Count that’s defined in the Account class, and stores the value in a new int variable named count.

nope i prefer two because it is simpler, i don't like all the powers you get

but that's my opinion
