This program should allow the user to enter the age in years and weight in pounds of an indefinite
number of people. Have the user enter the ages and weights as integer values. Use a sentinal value
of -1 when you are done entering the information. Calculate the average weight and age for all
the people. Print the average age and weight of all the people to the DOS screen. Print to the DOS
screen the number of people on which information was entered. Print the highest age and the lowest
age of all the ages entered. Print the highest weight and the lowest weight of all the weights entered.*/

I don't know how to implement the highest value, lowest value for weight and age into the above so it calculates with my already compiled program. I need this to calculate the age and weight with my program above. Any help? Please.
Scanner scan = new Scanner (System.in);
int age = 0, lowest = 0, highest = 0;
for (int i = 0; i <; i++) {
System.out.println("Enter a number");
age = scan.nextInt();
if (i == 0) {
lowest = age;
highest = age;
} // end if
else if (age < lowest)
lowest = age;
else if (age > highest)
highest = age;
