Java code to serie 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 using for while loop.

public class Fibonacci {
  public static void main(String[] args) {
    int n1 = 0, n2 = 1, n3, i, count = 10;
    System.out.print(n1 + " " + n2);//printing 0 and 1    

    for (i = 2; i < count; ++i)//loop starts from 2 because 0 and 1 are already printed    
    {
      n3 = n1 + n2;
      System.out.print(" " + n3);
      n1 = n2;
      n2 = n3;
    }
  }
}
