Answer 1

import java.util.*;
class Discount
{int cost;
String name;
double dc, amt;

void input()
{Scanner in = new Scanner(System.in);
System.out.println("Enter the name of the customer");
name = in.nextLine();
System.out.println("Enter the cost of the article");
cost = in.nextInt();
}

void cal()
{if (cost <= 5000)
dc = 0;
else if ((cost >= 5001) && (cost <= 10000))
dc = 0.10 * cost;
else if ((cost >= 10001) && (cost <= 15000))
dc = 0.15 * cost;
else if (cost > 15000)
dc = 0.20 * cost;
amt = cost - dc;
}

void display()
{System.out.println("Name of the customer\tCost\tDiscount\tAmount to be paid");
System.out.println(name + "\t\t" + cost + "\t" + dc + "\t\t" + amt);
}

public static void main(String args[])
{Discount dis = new Discount();
dis.input();
dis.cal();
dis.display();
}
}
