Print fibonacci series numbers in java

Fibonacci series numbers – A particular sequence of integers

logic –

First two numbers are 0 and 1, then next subsequent integer will be sum of the previous 2 numbers

let’s see few easy ways to achieve this –

public static void main1(String[] args) {
      int max = 10;
      int prev = 0;
      int next = 1;
      int sum = 1;
      System.out.println(prev);
      for(int i = 1; i < max; i++)
      {
	 System.out.println(sum);
	 sum = prev + next;
	 prev = next;
	 next = sum;
      }
}

[or]

public static void main(String[] args) {	
	int max = 10;
        int a = 0;
	int b = 1;
        for (int i = 0; i < max; i++)
	{
	    System.out.println(a);
	    a = a+b;
	    b = a-b;
	}
}

Output:
