Greetings to all experts,

I am a newbie here in Java OOP and is struggling in practicing how to code a OO program, using Java. I hope anyone can give me a head start please.

Here is the requirement which i am suppose to complete:

**Input**

The first line of the input contains an integer N (1 <= N <= 100) denoting the number of people in the group. The next N lines contain the information (name, height in centimeters, and weight in kilograms) of the people in the group.

**Output**

Output the name of the shortest and tallest people in the group with format:

Suppose A is the shortest and B is the tallest person in the group, then the output will be:

A is the shortest with BMI equals to C.

B is the tallest with BMI equals to D.

where C is the BMI for A and D is the BMI for B. Output the BMI with 2 digit after the decimal point rounded to the nearest integer.

**Sample Input**

5

Diamond 178 55

Jarod 160 80

Douglas 180 60

Rod 151 48

Joe 178 55

**Sample Output**

Rod is the shortest with BMI equals to 21.05.

Douglas is the tallest with BMI equals to 18.52.

Thus, I have created 2 classes namely **Person** and **Measurement** (main method can be found in here). Below are the codes which i am working on:

```
import java.util.*;
// create an object called Person that has attribute name, height, weight
class Person {
// declare the attributes
String name;
double height, weight;
// declare the constructor
public Person (double h, double w)
{
height = h;
weight = w;
}
/* use this method to compute the BMI for that person
* PRE-Condition :
* POST-Condition :
*/
public double computeBMI() {
return (weight / height * height);
// implement the BMI formula
}
}
public class Measurement {
public static void main(String[] args) {
// declare the necessary variables
int count;
// declare a Scanner object to read input
Scanner scan = new Scanner(System.in);
// read input and process them accordingly
count = scan.nextInt();
Person.name = scan.nextLine();
Person.h = scan.nextDouble();
Person.w = scan.nextDouble();
// simulate the problem
// output the result
System.out.println(Person.computeBMI);
}
}
```

Thank you so much for all your guidance.
