PLEASE GIVE ANSWER IN BUFFERED CLASS

Answer 1

import java.io.*;
class discount
{
public static void main( )throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in))
int price;
double amt1=0.0,amt2=0.0;
System.out.println("Enter price of entity");
price=Integer.parseInt(br.readLine( ));
amt1=price -(30*price)/100.0;
amt2=price-(20*price)/100.0;
amt2=amt2-(10*amt2)/100.0;
if(amt2>amt1)
System.out.println("Shopkeeper 1");
else if(amt2<amt1)
System.out.println("Shopkeeper 2");
else
System.out.println("Both are equal");
}
}

Answer 2

import java.io.*;

class Successive{

public static void main(String args[])throws IOException{

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

System.out.print("Price: ");

double price = Double.parseDouble(br.readLine());

double discount = 30.0 / 100 * price;

double amount1 = price - discount;

double discount1 = 20.0 / 100 * price;

double amount2 = price - discount1;

double discount2 = 10.0 / 100 * amount2;

amount2 = amount2 - discount2;

System.out.println("Amount 1: " + amount1);

System.out.println("Amount 2: " + amount2);

}

}
