Hi friend,


Code to solve the problem :

import java.io.*;
class SalesTax
{
public static void main(String[] args) throws Exception
{

double salesTax = salesTax();
System.out.println("salesTax : " + salesTax);
}

public static double salesTax() throws Exception
{
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader bufReader = new BufferedReader(isr);
System.out.println("Enter the number ");
double sales_tax=0;
double subtotal = Double.parseDouble(bufReader.readLine());
boolean isFresno=Boolean.parseBoolean(bufReader.readLine());
System.out.println("Enter the number " + subtotal);
System.out.println("Enter the number " + isFresno);


try
{
if(isFresno==false)
{
sales_tax= .0775;
}
else if(isFresno==true)
{
sales_tax= .0775+.001;
}
if(subtotal<=0)
{
throw new IllegalArgumentException("Subtotal must be greater than zero.") ;
}
}
catch(Exception e)
{
System.out.println(e.getMessage());
}

return sales_tax;
}
}

Hi friend

i hope the follwing code helps u...


import java.io.*;

class sales_tax_ex extends Exception
{
public static void main(String[] args)
{
double subtotal= 10,salestax;
boolean isFrensco=true;

salestax=calculate(subtotal,isFrensco);

if(subtotal<=0)
{ System.err.println("Subtotal must be greater than Zero");
throw new IllegalArgumentException();
}

System.out.println("sales tax :" +salestax);

}

static double calculate(double st,boolean b)
{
double salestax=0;

if(b==false)
salestax=0.0775;

else
salestax += 0.001;

return salestax;
}

}


/* u can change the isfrenso and subtotal value at run time by making some changes in the code */

Thanks..
