Quick Java Programming question....

[Skiguy411]

I am suppose to write a public method named multiply which accepts two doubles multiplies them, and returns a double.

I'm just starting to learn java and so I'm not** exactly sure how to write that.

Read your book? Use class notes? Ask a professor? Google?

Come on man that is standard stuff and the wrong place to be asking. You can easily accomplish that task. In literally 2 min.

Private or Public?: public
Return type: double
Method Name: multi
Inputs: (double a, double b) {

That's a huge hint.

You're exactly sure? Not just sure, but exactly sure?

I figured with ATOTs wisdom, it would be the fastest and most painless way to find out.

And I think you meant that "I'm NOT exactly sure how to write that". if you were exactly sure why are you asking?

 

[jaybert]

public static double multiply(double a, double b) {
return a * b;
}

 

[dwell]

public double multiply(double d1, double d2) { return d1 * d2; }

n00b

wow that is fvcking pathetic. i really really hope for your sake that your major has nothing to do with computers at all, as in, you will never ever touch a computer while on your job after you have a degree.

Most people would start out by reading the book, or paying attention to the lectures in class, where the professor absolutely went over this.

Do yourself a favor and switch majors.

This is the simplest possible example of a function returning a value, this was covered in class and your book goes into excessive detail.

You need to learn basic concepts like this. If you just learn to copy and paste other people's code you will fail the midterm and final, and you will be hopelessly unprepared for any future classes.

Programming is not like a history class where you memorize some facts and spew them out. It's more like a math class where you learn tools and how to use them.

Learn the concepts or switch to a business major.

public multiply(double a, double b){
a * b;
return 42d;
}

 

[tfinch2]

public static double multiply(double a, double b)
{
double c = a * b;
if (c > 0)
return c;
else
system.exit(0);

return c;
}

This is the best example. Don't listen to these noobs. 😛

Exactly! If you're going to copy-paste answers this one will impress the professor more with its variety of responses and attention to detail.
