The Fibonacci arrangement is where the following term is the total of pervious two terms. The initial two terms of the Fibonacci grouping is 0 trailed by 1.

**Display Fibonacci series using for loop**

public class Fibonacci {

public static void main(String[] args) {

int n = 10, t1 = 0, t2 = 1;

System.out.print("First " + n + " terms: ");

for (int i = 1; i <= n; ++i)

{

System.out.print(t1 + " + ");

int sum = t1 + t2;

t1 = t2;

t2 = sum;

}

}

}

When you run the program, the yield will be:

0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 +

In the above program, first (t1) and second (t2) terms are introduced to initial two terms of the Fibonacci arrangement 0 and 1 separately.

At that point, for circle emphasizes to n (number of terms) showing the entirety of past two terms put away in factor t1.

**Display Fibonacci series using while loop**

public class Fibonacci {

public static void main(String[] args) {

int i = 1, n = 10, t1 = 0, t2 = 1;

System.out.print("First " + n + " terms: ");

while (i <= n)

{

System.out.print(t1 + " + ");

int sum = t1 + t2;

t1 = t2;

t2 = sum;

i++;

}

}

}

The yield is same as the above program.

In the above program, not at all like a for circle, we need to increase the estimation of I inside the body of the circle.

In spite of the fact that the two projects are in fact adjust, it is smarter to use for circle for this situation. This is on the grounds that the quantity of emphasis (from 1 to n) is known.

**Display Fibonacci series upto a given number (instead of terms)**

public class Fibonacci {

public static void main(String[] args) {

int n = 100, t1 = 0, t2 = 1;

System.out.print("Upto " + n + ": ");

while (t1 <= n)

{

System.out.print(t1 + " + ");

int sum = t1 + t2;

t1 = t2;

t2 = sum;

}

}

}

When you run the program, the yield will be:

Upto 100: 0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 + 55 + 89 +

Rather than showing the arrangement upto a particular number, this program shows it until a given number (100).

For this, we simply need to think about the whole of last two numbers (t1) with n.

In the event that t1 is not exactly or equivalents to n, print t1. Else, we're done showing all terms.
