Practice questions on Java Classes and Objects – Find price on the basis of Fabric

Define a class Garments with the following description :

• Members are : GCode of type String, GType of type String, GSize of type integer, GFabric of type string, GPrice of type float.
• Member functions :
• A function Assign() which calculates and assigns the value of GPrice as follows:
• For the value of GFabric “COTTON”,

• For GFabric other than “COTTON” the above mentioned GPrice gets reduced by 10%.
• A constructor to assign initial values of GCode, GType and GFabric with the word “Not Allowed” and GSize and GPrice with 0.
• A function Input() to input the values of the data members GCode, Gtype, GSize and GFabric and invoke the Assign() function.
• A function Display() which displays the content of all the data members for a Garment.

Solution

import java.util.*;

class Garments
{
    String GType;
    String GCode;
    int GSize;
    String GFabric;
    float GPrice;
    
    //define a constructor
    Garments()
    {
        GCode="Not Allowed";
        GType="Not Allowed";
        GFabric="Not Allowed";
        GSize=0;
        GPrice=0.0f;
    }

    public void Assign(){
        if(GFabric.equals("Cotton"))
        {
            if(GType.equals("Trouser"))
                GPrice=1300;
            if(GType.equals("Shirt"))
                GPrice=1100;
        }
        else
        {
            if(GType.equals("Trouser"))
                GPrice=1170;
            if(GType.equals("Shirt"))
                GPrice=990;
        }
    }

    public void Input(){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter Garment Code : ");
        GCode=sc.next();
        System.out.println("Enter Garment type : ");
        GType=sc.next();
        System.out.println("Enter Garment Fabric : ");
        GFabric=sc.next();
        System.out.println("Enter Garment Size : ");
        GSize=sc.nextInt();
        Assign();
    }
    

    public void Display(){
        System.out.println("Garment Code   : "+GCode);
        System.out.println("Garment Type   : "+GType);
        System.out.println("Garment Fabric : "+GFabric);
        System.out.println("Garment Size   : "+GSize);
        System.out.println("Garment Price  : "+GPrice);
    }
}

class GarmentsData
{
   public static void main(String args[])
   {
     Garments gar=new Garments();  
     gar.Input();
     gar.Display();
   }
}

Save the above Program with “GarmentsData.Java” then compile it with the following commands: 

javac GarmentsData.java    // to compile the code

java GarmentsData         // to run the code

Output is :

Enter Garment Code :
101
Enter Garment type :
Shirt
Enter Garment Fabric :
Cotton
Enter Garment Size :
32

Garment Code   : 101
Garment Type   : Shirt
Garment Fabric : Cotton
Garment Size   : 32
Garment Price  : 1100.0
