Please help me comment these lines of code. Please not these are just some lines of code that have been taken from the java program I am creating which is a coin toss program. I do not need you to create one. Just comment what the lines of code below

private static String sideUp;

}

public void toss() { Random in = new Random(); int x = in.nextInt(); if (x % 2 == 0) sideUp = "Heads"; else sideUp = "Tails"; }

public static void main(String[] args) { int tail = 0, head = 0;

System.out.println(" Tossing coin 20 times:-"); for (int i = 1; i <= 20; i++) { coin.toss(); if (coin.getFace().equals("tails")) tail++; else head++;

. any update
