I need an explanation for this Java question to help me study.
3. The following program reads three integers and prints the average. Fill in the blanks so that it will work correctly.
public class Average
public static void main(String args)
int val1, val2, val3;
Scanner scan = new Scanner(System.in);
val1 = scan.nextInt(); // get three values from user
val2 = scan.nextInt();
val3 = scan.nextInt();
System.out.println(“Please enter three integers and ” +
“I will compute their average”);
average = (val1 + val2 + val3) / 3; //compute the average
System.out.println(“Average is ” + average); //print the average
