Program:
1. (Using for loop)
public class Fibonacci
{
public static void main(String[] args)
{
int a = 0, b = 1;
System.out.println(“First 10 terms: “);
for (int i = 1; i <= 10; ++i)
{
System.out.println(a + ” “);
int sum = a + b;
a = b;
b = sum;
}
}
}
In the above program we use two variables that is a and b and assign the value 0 and 1 respectively. For loop is used to initialize the value of ‘i’ variable and increment it by 1. And we put the condition that is the ‘i’ must be less than or equal to 10. So we see the output of 10 numbers only.
2. Using while loop
public class Fibonacci
{
public static void main(String[] args)
{
int i = 1, a = 0, b = 1;
System.out.println(“First 10 terms: “);
while(i<=10)
{
System.out.println(a + ” “);
int sum = a + b;
a = b;
b = sum;
i++;
}
}
}
In the above code instead of for loop we use the while loop and incremented I variable in the middle loop. The output of both code is exactly same.
Output:
