Hi;
See the code below;
import java.io.*;
public class Main {
public static void main(String[] args) throws IOException {
Data dt = new Data("Name", "Last", "Somewhere on earth", "Student");
dt.setUnitPrice(10.96);
dt.setQuantity(69);
dt.calculateTotal(0.75);
System.out.println(dt.toString());
return;
}
}
class Data {
private String f_name, l_name, address, job;
private int quantity;
private double single_price, total ,discount;
public Data(String f_name, String l_name, String address, String job) {
this.f_name = f_name;
this.l_name = l_name;
this.address = address;
this.job = job;
this.single_price = this.total = this.quantity = 0;
}
public Data(String f_name, String l_name) {
this(f_name, l_name, "", "");
}
public void setUnitPrice(double price) {
this.single_price = price;
}
public void setQuantity(int qt) {
this.quantity = qt;
}
public double calculateTotal() {
return this.calculateTotal(0);
}
public double calculateTotal(double discount) {
this.discount = discount;
this.total = this.single_price * this.quantity * ( 1 - discount );
return this.total;
}
public String toString() {
return this.l_name + ", " + this.f_name + "\n" + this.address +
"\n" +
this.job + "\n" + this.quantity + " each at " +
/*Double.formatDouble(*/this.single_price/*, 2)*/ +
"$" + " costs " + this.total + "$. " + ((this.discount != 0) ?
("(Discount of " + this.discount * 100 + "%.)\n") : (""));
}
}
With the hope of rising of Mahdi;
