Fibonacci series - TutorialFlow

Fibonacci Series is one of the basic questions in Java., to check the programmer has a basic understanding of logic implementation in java.In Fibonacci series, the current number is always the sum of previous two numbers.Fibonacci series is initialized with 0 & 1.0, 1, (0+1)2, (1+2)3, (2+3)5, (3+5)8, (5+8)13….

public class Fibonocci {

	public static void main(String args[]) {

		int previousNumber = 0;
		int recentNumber   = 1;
		
		int nextNumber;
		int count = 20;
		System.out.print(previousNumber + " " + recentNumber);

		for (int i = 2; i < count; ++i)
		
			nextNumber = previousNumber + recentNumber;
			System.out.print(" " + nextNumber);

			previousNumber = recentNumber;
			recentNumber = nextNumber;
		}
	}
}

public class Fibonocci {

public static void main(String args[]) {

int previousNumber = 0;

int recentNumber = 1;

int nextNumber;

int count = 20;

System.out.print(previousNumber + " " + recentNumber);

for (int i = 2; i < count; ++i)

nextNumber = previousNumber + recentNumber;

System.out.print(" " + nextNumber);

previousNumber = recentNumber;

recentNumber = nextNumber;

}

Output

0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181
