Let us observe the Java code given below to gain a better understanding of While Loop: Method 2: With recursion. In the above program, first (t1) and second (t2) terms are initialized to the first two terms of the Fibonacci series 0 and 1 respectively. Display Characters from A to Z using loop. Can "vorhin" be used instead of "von vorhin" in this sentence? It's because the number of iteration (from 1 to n) is known. I am trying to print a Fibonacci sequence using a do-while loop in java and can't understand this. Then using while loop the two preceding numbers are added and printed. The for loop iterates up to the number entered by the user. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. A basic Fibonacci sequence using a do-while loop would look like the following: Since you want the terms of Fibonacci up to 100,just change while (prevVal <= 100); to while (prevVal+prevPrevVal <= 100); Thanks for contributing an answer to Stack Overflow! The functionality can be achieved in two ways by simply using a loop or recursion. It can be represented by the below equation Fn = … How do I efficiently iterate over each entry in a Java Map? Example 2: 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++; } } } wiki.answers.com/Q/Fibonacci_series_with_do_while_in_java.
