Java Program to Find Total Amount After Adding Tax
We have to find total amount after adding tax amount.
Let’s take an scenario of tax imposed on price.
- If total amount of product is below 1000 then No tax on total amount.
- If total amount of product crosses 1000 but below 5000 then 5% tax on total amount.
- If total amount of product crosses 5000 but below 10000 then 8% tax on total amount.
- If total amount of product crosses 10000 then 10% tax on total amount.
Let’s see different ways to find total amount after adding tax,
Method-1: Java Program to Find Total Amount After Adding Tax By Using Static Input Value
Approach:
- Declare initial amount value.
- Check as per above mentioned tax condition and find tax based on initial amount.
- Then after adding the tax with the amount, we can get total amount.
- Print total amount.
Program:
public class Main
{
public static void main(String[] args)
{
//amount declared
double amount = 2000;
//double variable 'tax' initualized to 0
double tax=0;
//double variabe 'totalAmount' initialized to 0
double totalAmount = 0;
//if amount below than 1000 then no tax
if(amount < 1000)
{
totalAmount=amount;
}
//if amount is in between 1000 and 5000
//then 5% tax
else if ((amount > 1000) && (amount < 5000))
{
tax=(amount*5)/100;
totalAmount=amount+tax;
}
//if amount is in between 5000 and 10000
//then 8% tax
else if ((amount > 5000) && (amount < 10000))
{
tax=(amount*8)/100;
totalAmount=amount+tax;
}
//else amount is more than 10000
//then 10% tax
else if (amount > 10000)
{
tax=(amount*10)/100;
totalAmount=amount+tax;
}
//printing total amount after adding tax
System.out.println("Total Amount " + totalAmount);
}
}
Output: Total Amount 2100.0
Method-2: Java Program to Find Total Amount After Adding Tax By Using User Input Value
Approach:
- Take user input of initial amount value.
- Check as per above mentioned tax condition and find tax based on initial amount.
- Then after adding the tax with the amount, we can get total amount.
- Print total amount.
Program:
import java.util.*;
public class Main
{
public static void main(String[] args)
{
//Scanner class object created
Scanner sc=new Scanner(System.in);
System.out.println("Enter amount: " );
//taking amount value input from user
double amount = sc.nextInt();
//double variable 'tax' initualized to 0
double tax=0;
//double variabe 'totalAmount' initialized to 0
double totalAmount = 0;
//if amount below than 1000 then no tax
if(amount < 1000)
{
totalAmount=amount;
}
//if amount is in between 1000 and 5000
//then 5% tax
else if ((amount > 1000) && (amount < 5000))
{
tax=(amount*5)/100;
totalAmount=amount+tax;
}
//if amount is in between 5000 and 10000
//then 8% tax
else if ((amount > 5000) && (amount < 10000))
{
tax=(amount*8)/100;
totalAmount=amount+tax;
}
//else amount is more than 10000
//then 10% tax
else if (amount > 10000)
{
tax=(amount*10)/100;
totalAmount=amount+tax;
}
//printing total amount after adding tax
System.out.println("Total Amount after adding tax: " + totalAmount);
}
}
Output: Enter amount: 6000 Total Amount after adding tax: 6480.0
Method-3: Java Program to Find Total Amount After Adding Tax By Using User Defined Method
Approach:
- Take user input of initial amount value.
- Then call a method by passing this amount as parameter.
- Inside method check as per above mentioned tax condition and find tax based on initial amount.
- Then after adding the tax with the amount, we can get total amount.
- Print total amount.
Program:
import java.util.*;
public class Main
{
public static void main(String[] args)
{
//Scanner class object created
Scanner sc=new Scanner(System.in);
System.out.println("Enter amount: " );
//taking amount value input from user
double amount = sc.nextInt();
//calling a user defined method findAmount()
findAmount(amount);
}
//findAmount() method to find total amount after adding tax
public static void findAmount(double amount)
{
//double variable 'tax' initualized to 0
double tax=0;
//double variabe 'totalAmount' initialized to 0
double totalAmount = 0;
//if amount below than 1000 then no tax
if(amount < 1000)
{
totalAmount=amount;
}
//if amount is in between 1000 and 5000
//then 5% tax
else if ((amount > 1000) && (amount < 5000))
{
tax=(amount*5)/100;
totalAmount=amount+tax;
}
//if amount is in between 5000 and 10000
//then 8% tax
else if ((amount > 5000) && (amount < 10000))
{
tax=(amount*8)/100;
totalAmount=amount+tax;
}
//else amount is more than 10000
//then 10% tax
else if (amount > 10000)
{
tax=(amount*10)/100;
totalAmount=amount+tax;
}
//printing total amount after adding tax
System.out.println("Total Amount after adding tax: " + totalAmount);
}
}
Output: Enter amount: 12000 Total Amount after adding tax: 13200.0
