Hints

Every class inherits toString() from Object; override it.

@Override makes the compiler check you really override something.

Solution explanation

All Java classes extend Object, which provides toString, equals and hashCode.

import java.util.Scanner;

class Product {
    final String name;
    final double price;

    Product(String name, double price) {
        this.name = name;
        this.price = price;
    }

    @Override
    public String toString() {
        return String.format("%s @ %.2f", name, price);
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        for (int i = 0; i < n; i++) {
            System.out.println(new Product(sc.next(), sc.nextDouble()));
        }
    }
}
