Answer to Question #316481 in Java | JSP | JSF for Dreaper

Question

1. Create a project named LabExer2
2. Construct a simple purchasing program based on the UML Class Diagram below.

• itemName: String
• itemPrice: double
• itemQuantity: int
• amountDue: double

• setItemName(StringnewitemName): void
• setTotalCost(int quantity, double price): void
• getItemName(): String
• getTotalCost(): double
• readInput(): void
• writeOutput(): void

storing the input to the next variable name based on data type

For String s.nextLine()

For int s.nextInt()

For double: s.nextDouble()

Answer 1

import java.util.Scanner;

class SecondClass{
    String itemName;
    double itemPrice;
    int itemQuantity;
    double amountDue;


    public void setItemName(String itemName){
        this.itemName = itemName;
    }

    public void setTotalCost(int quantity, double price){
        this.itemQuantity = quantity;
        this.itemPrice = price;
    }

    public String getItemName(){
        return itemName;
    }

    public double getTotalCost(){
        return itemPrice*itemQuantity;
    }

    public void readInput(){

    }

    public void writeOutput(){
        System.out.print(   "Name: " + getItemName() +
                            "\nTotalCost: "+ getTotalCost());
    }
}

public class LabExer2 {
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        SecondClass secClass = new SecondClass();

        System.out.print("Enter name: ");
        secClass.setItemName(s.nextLine());
        System.out.print("Enter quantity: ");
        int a = s.nextInt();
        System.out.print("Enter price: ");
        secClass.setTotalCost(a, s.nextDouble());

        secClass.writeOutput();
    }
}
