Do you know, what is Fibonacci numbers..?
These are numbers like 0, 1,1,2,3,5,8,13,21. . . . . . . . . .
How do you get these numbers . .?
First take numbers 0 and 1 as static. (Now numbers are 0, 1)
Last element is 1; its left element is 0, so add them, 0 + 1 = 1 (Now numbers is 0, 1, and 1)
Last element is 1, its left element is 1, so add them, 1 + 1 = 2 (Now numbers are: 0, 1, 1, and 2)
Last element is 2, its left element is 1, so add them, 2 + 1 = 3 (Now numbers are: 0, 1, 1, 2, and 3)
Last element is 3, its left element is 2, so add them, 3 + 2 = 5 (Now numbers are: 0, 1, 1, 2, 3, and 5)
Last element is 5, its left element is 3, so add them, 5 + 3 = 8 (Now numbers are: 0, 1, 1, 2, 3, 5, and 8)

Now let’s write a java program to print Fibonacci numbers up to a limit: (Learn how to Compile and Run a Java file)

 import java.io.*; class fibonacci {    long f1=0;    long f2=1;    long f3=0;    int n; void get() throws IOException   {      BufferedReader Br = new BufferedReader(new InputStreamReader(System.in));      System.out.print("Enter a limit : ");      n=Integer.parseInt(Br.readLine());  } void display()   {           for(int i=0;i

Output

Java program to print "N" Fibonacci  numbers:

 import java.io.*; class fibonacci {    long f1=0;    long f2=1;    long f3=0;    int n; void get() throws IOException   {      BufferedReader Br = new BufferedReader(new InputStreamReader(System.in));      System.out.print("How many numbers : ");      n=Integer.parseInt(Br.readLine());  } void display()   {           for(int i=0;i

Output
