Explanation:
#A java program
import java.util.*;
class ShowRoom
{
String name;
long mobno;
double cost,dis, amount;
ShowRoom()
{
name="";
mobno=0;
cost=dis=amount=0;
}
void input()
{
Scanner sc=new Scanner (System.in);
System.out.println("enter the customer name,mobile number and cost");
name=sc.nextLine();
mobno=sc.nextLong();
cost=sc.nextDouble();
}
void calculate ()
{
if(cost<=10000)
{
dis=0.05*cost;
amount=cost - dis;
}
else if(cost<=20000)
{
dis=0.10*cost;
amount=cost- dis;
}
else if(cost<=35000)
{
dis=0.15*cost;
amount=cost - dis;
}
else if(cost>35000)
{
dis=20*cost;
amount=cost-dis;
}
}
void display()
{
System.out.println("Customer name:"+name);
System.out.println("mobile number:"+mobno);
System.out.println("amount to be paid after discount:"+amount);
}
public static void main (String args [])
{
ShowRoom obj=new ShowRoom ();
obj.input();
obj.calculate();
obj.display();
}
}
Some additional information:
*the above program is an example of real life problem program.
*java supports constructor.
*a constructor calls itself at the time of object creation (instantion)
