1.The classes that convert primitives to objects are called ____________ classes.
2.Suppose class Automobile has a static method called getMileage with the following signature:
public static double getMileage(String make, String model)
How would you call this method for a Ford Mustang and store the result in double mpg?
3.Name the three of the four primitive data types with which wrapper classes primarily deal.
4.Write a line of code that will convert double dx into an object. Call the object dd.
5.A) Write a line of code that will create an object that could be used to generate random numbers.
B: Use the object created in part "A" in a line of code that will generate integers in the range from 0 (inclusive) to 100 (inclusive).

1. wrapper
3. int, double, and boolean
4. double dx = new double(dd);

are those right?

That is technically correct, in that it wraps the value as an object, but the more specific definition is "boxed value types."

2.
Yes. The others are short, long, float and char.
Nope. The type double is a primative. Calling new doesn't work. You can rely on autoboxing:

1. wrapper
2. double mpg = Automobile.getMileage(Ford, Mustang);
3. int, double, boolean
4. double dd = new double(dx);
5a. Random don = new Random();
5b. int num = don.nextInt(101);


How are these lookin? All right?

Error! You have to pass strings, not the values of tokens.

??

Which word did you not understand?

tokens. i dont get what u mean by that

He means pay attention in class, this shit is easy and you shouldn't really need to ask the internet about it.

It means a symbol. In your statement, you're passing the symbols Ford and Mustang, both of which are completely meaningless. Pass string values, "Ford" and "Mustang"
