In Java modulo operation -1 % 3 = -1 , One of the answer said that -1 % 3 =2 But java doesn't calculate like that. How can find result of 2 in -1 % 3 Here the sample java program I run: class Remainder {

  public static void main (String args[]) {

    int i = -1;
    int j = 3;

    System.out.println("i is " + i);
    System.out.println("j is " + j);

    int k = i % j;
    System.out.println("i%j is " + k);
  }

}

One more question, let assume I choose xth number of block as A and yth number of Block as B, should the new block ( the block which number A-B) put to the location of A? Let me explain I choose 2nd (as A) and 5th (as B) block the number of new block would be (A - B) -3 should I set this block in the position of A?
