mobile,10000,20

shoe,5000,10

watch,6000,15

laptop,35000,5

Sample Output 1:

Explanation: the discount on mobile is 2000, the discount on shoe is 500, the discount on watch is 900 and the discount on laptop is 1750. So the discount on shoe is the minimum.

Answer 2

Answer:

import java.util.*;

class Product implements Comparable<Product> {

private final String name;

private final double price;

private final double discount;

public Product(String name, double price, double discount) {

this.name = name;

this.price = price;

this.discount = discount;

}

public Double getDiscountPrice() {

return price * discount / 100;

}

Override

public int compareTo(Product other) {

return this.getDiscountPrice().compareTo(other.getDiscountPrice());

}

@Override

public String toString() {

return name;

}

}

class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

List<Product> products = new ArrayList<>();

int n = scanner.nextInt();

for (int i = 0; i < n; ++i) {

String[] inputs = scanner.next().split(",");

String name = inputs[0];

double price = Double.parseDouble(inputs[1]);

double discount = Double.parseDouble(inputs[2]);

Product product = new Product(name, price, discount);

products.add(product);

}

products.stream()

.filter((product) -> product.getDiscountPrice().equals(Collections.min(products).getDiscountPrice()))

.forEach(System.out::println);

}

}
