Printing Fibonacci Numbers
This program prints out the first 20 numbers in the Fibonacci sequence. Each
term is formed by adding together the previous two terms in the sequence,
starting with the terms 1 and 1.
Code:
public class Fibonacci {
public static void main(String[] args) {
int n0 = 1, n1 = 1, n2; // Initialize variables
System.out.print(n0 + " " + // Print first and second terms
n1 + " "); // of the series
for (int i = 0; i < 18; i++) { // Loop for the next 18 terms
n2 = n1 + n0; // Next term is sum of previous two
System.out.print(n2 + " "); // Print it out
n0 = n1; // First previous becomes 2nd previous
n1 = n2; // And current number becomes previous
}
System.out.println(); // Terminate the line
}
}
