Slip2

 Q1) Write a program to read the First Name and Last Name of a person, his weight and height using command line arguments. Calculate the BMI Index which is defined as the individual's body mass divided by the square of their height. (Hint : BMI = Wts. In kgs / (ht)2) 

import java.util.Scanner;

public class Slip2_1

{

    public static void main(String[] args) 

    {

        double wt, ht;

String fname,lname;

fname=args[0];

lname=args[1];

wt=Double.parseDouble(args[2]);

ht=Double.parseDouble(args[3]);

double bmi=wt/(ht*ht);

        System.out.println("Person Name : "+fname+" "+lname);

        System.out.println("BMI : "+bmi);

    }

}

 Q2) Define a class CricketPlayer (name,no_of_innings,no_of_times_notout, totatruns, bat_avg). Create an array of n player objects .Calculate the batting average for each player using static method avg(). Define a static sort method which sorts the array on the basis of average. Display the player details in sorted order.
