Alternative method to Calculate the final price of the Laptop or Desktop after certain discount of total cost according to criteria

import java.util.Scanner; //Importing Scanner class from util package
public class Purchase

        char ch=new Scanner(System.in).next().charAt(0); //Getting Character from user
                 
                if (ch=='L'|| ch=='l') //Checking condition
                {

                    l.calcLaptop();

        System.out.println("Enter your Address"); //Instruction to user
        address= new Scanner(System.in).nextLine();
   
        System.out.println("Enter the cost price of Laptop: "); //Instruction to user

    }


public double calcLaptop() //Return type,Non parameterized method
    {
        //Conditions according to the above criteria
        if(purchase<=25000)
        {
            finalPrice= purchase-0;
        }
        else if(purchase>25000 && (purchase<=57000))
        {
            finalPrice= purchase-((5*purchase)/100);
        }
        else if(purchase>57000 && (purchase<=100000))
        {
            finalPrice= purchase-((7.5*purchase)/100);
        }
        else if(purchase>100000)
        {
            finalPrice= purchase-((10*purchase)/100);
        }
        return finalPrice; //Returning the result value of variable finalprice
    }



public double calcDesktop() //Return type,Non parameterized method
    {
        //Conditions according to the above criteria
        if(purchase<=25000)
        {
            finalPrice= purchase-((5*purchase)/100);
        }
        else if(purchase>25000 && (purchase<=57000))
        {
            finalPrice= purchase-((7.5*purchase)/100);
        }
        else if(purchase>57000 && (purchase<=100000))
        {
            finalPrice= purchase-((10*purchase)/100);
        }
        else if(purchase>100000)
        {
            finalPrice= purchase-((15*purchase)/100);
        }
        return finalPrice; //Returning the result value of variable finalprice
    }



public void display() //Non return type,Non parameterized method
    {
        //Printing results
        System.out.println("Your Name = "+name);
        System.out.println("Your Address = "+address);
        System.out.println("Final Price after discount = "+finalPrice);
    }
}


 Output of the above program is:-

   Enter L to get access to Laptop section and D to get access to Desktop section
   l
   Enter your Name:
   Gaman Aryal
   Enter your Address
   Pepsicola
   Enter the cost price of Laptop:
   175000
   Your Name = Gaman Aryal
   Your Address = Pepsicola
   Final Price after discount = 157500.0

Java program using Scanner Class

Scanner Class in Java The scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings. It is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming. To create an object of Scanner class, we usually pass the predefined object System.in, which represents the standard input stream. We may pass an object of class File if we want to read input from a file. To read the numerical values of a certain data type XYZ, the function to use is nextXYZ(). For example, to read a value of type short, we can use nextShort() To read strings, we use nextLine(). To read a single character, we use next().charAt(0). next() function returns the next token/word in the input as a string and charAt(0) funtion returns the first character in that string Program to calculate import java.util.Scanner; //Calli...
