Answer:
1)
officeAC = new AirConditioner();
officeAC.turnOn();
2)
officeAC = new AirConditioner();
officeAC.turnOn();
officeAC.setTemp(69);
Explanation:
1)
In the first statement a new object of the class AirConditioner whose reference is assigned to the officeAC. new is a keyword which creates an object of the class.
Next statement uses the method turnOn(). Reference to the new object officeAC is used to invoke this method turnOn().
2) The first two statements works the same as in 1)
The last statement invokes a method setTemp() using the reference variable and passes the value 69 to this method to set the desired temperature.

Answer:
Following are the program in the Python Programming Language.
#set list type variable and initialize the elements
myPizza = ['Margarita', 'Capsicum and onion', 'Chicken']
#set variable and initialize the elements
frndPizzas = myPizza[:]
#append value in list variable
myPizza.append('Corn')
#append value in list variable
frndPizzas.append('paperica')
#print message
print("My pizzas are:")
#set the for loop and print elements of 1st list
for pizza in myPizza:
print(pizza)
#print message
print("\nFriend's pizzas are:")
#set the for loop and print elements of 2st list
for frndsPizza in frndPizzas:
print(frndsPizza)
<u>Output</u>:
My pizzas are:
Margarita
Capsicum and onion
Chicken Corn
Friend's pizzas are:
Margarita Capsicum and onion Chicken paperica
Explanation:
<u>Following are the description of the program</u>:
- Set a list data type variable that is 'myPizza' and initializes elements in it.
- Set another list data type variable that is 'frndPizzas' and initializes elements in it.
- Append one-one element in both of the list data type variables.
- Set the for loops to print the elements of both list data type variables.
2 I think because 2 I think is binary I’m sorry if this is wrong
