help me explain the code line by line

import java.util.Scanner;

public class program {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

float total =0;

double average = 0.0;

int numOfNeg = 0;

int numOfPos = 0;

int numOfValues = 0;

int value;

System.out.print("Enter an integer, the the input" + "ends if it is 0:");

value = scan.nextInt();

while (value != 0) {

if (value > 0) {

numOfPos++;}

else if (value < 0) {

numOfNeg++;}

numOfValues++;

total += value;

value = scan.nextInt();

if (numOfValues == 0) {

System.out.println("Number are entered" + " except 0");}

else {

System.out.println("The number of positives" + " is ");

System.out.println("The number of negatives" + " is ");

System.out.printf("The total is %.1f ", total);

System.out.printf("The average is %.2f ", average);

}

}

}

}
