Write a Java Program to Display Fibonacci Series
PROGRAM: Java Program to Display Fibonacci Series
/*Java Program to Display Fibonacci Series*/
1. Display Fibonacci Series Using for Loop
class Main {
public static void main(String[] args) {
int n = 10, firstTerm = 0, secondTerm = 1;
System.out.println(“Fibonacci Series till ” + n + ” terms:”);
for (int i = 1; i <= n; ++i) {
System.out.print(firstTerm + “, “);
// compute the next term
int nextTerm = firstTerm + secondTerm;
firstTerm = secondTerm;
secondTerm = nextTerm;
}
}
}
2: Display Fibonacci series using while loop
class Main {
public static void main(String[] args) {
int i = 1, n = 10, firstTerm = 0, secondTerm = 1;
System.out.println(“Fibonacci Series till ” + n + ” terms:”);
while (i <= n) {
System.out.print(firstTerm + “, “);
int nextTerm = firstTerm + secondTerm;
firstTerm = secondTerm;
secondTerm = nextTerm;
i++;
}
}
}
3: Display Fibonacci series up to a given number
class Fibonacci {
public static void main(String[] args) {
int n = 100, firstTerm = 0, secondTerm = 1;
System.out.println(“Fibonacci Series Upto ” + n + “: “);
while (firstTerm <= n) {
System.out.print(firstTerm + “, “);
int nextTerm = firstTerm + secondTerm;
firstTerm = secondTerm;
secondTerm = nextTerm;
}
}
}
