Java Fibonacci number generator

Re: Java Fibonacci number generator

I don't see how I'm going to print out the numbers though.

Making my own array would probably be better anyways. I could use with figuring out how to use it.

It's an object.

A simple toString() should do it.

Then print out the string.

http://java.sun.com/j2se/1.4.2/docs/api/java/math/BigInteger.html#toString()

toString

public String toString()

Returns the decimal String representation of this BigInteger. The digit-to-character mapping provided by Character.forDigit is used, and a minus sign is prepended if appropriate. (This representation is compatible with the (String) constructor, and allows for String concatenation with Java's + operator.)

Overrides:
toString in class Object

Returns:
decimal String representation of this BigInteger.

Man BigInteger is sweet... I should go play around on the API more often. There are so many cool things on there that make Java life even simpler than it already is.
I've already handed in entire projects that were done using built-in classes, saving mountains of code. Teachers were pissed.

Yeah, that's nice, but I never actually figured out how to use classes either. >_>

I did get the array thing to work to print a number, except it's backwards.

Re: Java Fibonacci number generator

Are you using a for() counter to print out the array?
just do:

for(int i = ([I]arrayname[/I].length - 1); i >= 0; i--)
    System.out.print([I]arrayname[/I][i]);

Re: Java Fibonacci number generator

If you're using an array of ints you're majorly wasting space since you can use an array of bytes instead.

But BigInteger is by far the easiest way to do what you want to do. Case closed.
