Language java: Please rewrite the following lines using simpler way to read for beginner like me in coding I don't understand all these key words: 1. Vector q = new Vector<>(); //rewrite // push starting position of knight with 0 distance 2. q.add(new cell(knightPos[0], knightPos[1], 0)); //rewrite q.add, don't understand what is q.add means

3. while (!q.isEmpty()) //please rewrite all these key words { t = q.firstElement(); q.remove(0);

4.

q.add(new cell(x, y, t.dis + 1)); //rewrite q.add
