Create a class named Price this class contains three private

Create a class named \"Price\", this class

contains three private fields: price, quantity, couponvalue

Methods to get and set each of the fields

one constructor with three parameters, these three parameters can initialize price, quantity and coupon value as specified (for instance, 20, 10, 5)

computeprice() method with three parameters, they represent the price of a meal , the quantity ordered and a coupon value.

Multiple the price and quantity, reduce the result by the coupon value, and then add 20% tip and return the total price.

The class should contain a main() method which tests constructor method, get and set methods, and computeprice() methoduse system.out.println() to show different results

Solution

/* package whatever; // don\'t place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be \"Main\" only if the class is public. */
