Java Program to Print Right Triangle of Fibonacci Series Numbers Pattern

Write a Java program to print right triangle of Fibonacci series numbers pattern using for loop.

package Shapes4;

import java.util.Scanner;

public class FibonacciTriangleNum1 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Right Triangle Fibonacci Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("The Right Triangle of Fibonacci Series Numbers Pattern");
	
		for(int i = 1; i <= rows; i++)  
		{
			int First_Value = 0;
			int Second_Value = 1;
			for(int j = 1; j <= i; j++)
			{
				int Next = First_Value + Second_Value; 
				System.out.print(Next + " ");
                First_Value = Second_Value;
                Second_Value = Next;
			}
			System.out.println();
		}
	}

Java Program to Print Right Triangle of Fibonacci Series Numbers Pattern

This Java program prints the right-angled triangle of numbers in the Fibonacci series pattern using a while loop.

package Shapes4;

import java.util.Scanner;

public class FibonacciTriangleNum2 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Right Triangle Fibonacci Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("The Right Triangle of Fibonacci Series Numbers Pattern");
		
		int i, j, First_Value, Second_Value, Next;
		i = 1;
		
		while(i <= rows)  
		{
			First_Value = 0;
			Second_Value = 1;
			j = 1; 
			while(j <= i)
			{
				Next = First_Value + Second_Value; 
				System.out.print(Next + " ");
                First_Value = Second_Value;
                Second_Value = Next;
                j++;
			}
			System.out.println();
			i++;
		}
	}
}
