Program Examples

1. Program to Find fibonacci series of numbers

public class FibonacciEx 
{
	public static void main(String[] args) 
	{
		int prev = 0, current = 1, next,start = 0;
		System.out.print(prev+"\t"+current);
		while(start <= 10)
		{
			next = prev + current;
			System.out.print("\t"+next);
			
			prev = current;
			current = next;
			start ++;
		}
	}
}

Output

2. Program to Find Addition of Fibonacci series of numbers

public class FibonacciEx 
{
	public static void main(String[] args) 
	{
		int prev = 0, current = 1, next,start = 0,add=0;
		System.out.print(prev+"\t"+current);
		while(start <= 10)
		{
			next = prev + current;
			System.out.print("\t"+next);
			
			prev = current;
			current = next;
			start ++;
			add += next;
		}
		System.out.println("\nAddition : "+add);
	}
}
