Information & Algorithm

Define a class named FruitJuice with the following description:

Data Members	Purpose
int product_code	stores the product code number
String flavour	stores the flavour of the juice (e.g., orange, apple, etc.)
String pack_type	stores the type of packaging (e.g., tera-pack, PET bottle, etc.)
int pack_size	stores package size (e.g., 200 mL, 400 mL, etc.)
int product_price	stores the price of the product

Member Methods	Purpose
FruitJuice()	constructor to initialize integer data members to 0 and string data members to ""
void input()	to input and store the product code, flavour, pack type, pack size and product price
void discount()	to reduce the product price by 10
void display()	to display the product code, flavour, pack type, pack size and product price

Program Code

import java.util.Scanner;

public class FruitJuice
{
    private int product_code;
    private String flavour;
    private String pack_type;
    private int pack_size;
    private int product_price;
    
    public FruitJuice() {
        product_code = 0;
        flavour = "";
        pack_type = "";
        pack_size = 0;
        product_price = 0;
    }
    
    public void input() {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter Flavour: ");
        flavour = in.nextLine();
        System.out.print("Enter Pack Type: ");
        pack_type = in.nextLine();
        System.out.print("Enter Product Code: ");
        product_code = in.nextInt();
        System.out.print("Enter Pack Size: ");
        pack_size = in.nextInt();
        System.out.print("Enter Product Price: ");
        product_price = in.nextInt();
    }
    
    public void discount() {
        product_price -= 10;
    }
    
    public void display() {
        System.out.println("Product Code: " + product_code);
        System.out.println("Flavour: " + flavour);
        System.out.println("Pack Type: " + pack_type);
        System.out.println("Pack Size: " + pack_size);
        System.out.println("Product Price: " + product_price);
    }
    
    public static void main(String args[]) {
        FruitJuice obj = new FruitJuice();
        obj.input();
        obj.discount();
        obj.display();
    }
}

Output

Enter Flavour: orange
Enter Pack Type: PET bottle
Enter Product Code: 30
Enter Pack Size: 750
Enter Product Price: 60
Product Code: 30
Flavour: orange
Pack Type: PET bottle
Pack Size: 750
Product Price: 50

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
