Write a java program to compute net pay after deducting tax of 15% from the gross pay. Write a program to implement Employee class having fields as empno and basicpay, and methods for the following:

(i) compute Gross pay (receives hra% and da% as parameters and computes gross pay as basic + basic hra% + basic*da%).

(ii) compute net pay after deducting tax of 15% from the gross pay.

(iii) display the payslip

The code for : Write a java program to compute net pay after deducting tax of 15% from the gross pay.

import java.util.*;
class Employee
{
static int empNo;
static double grossP,basic,netpay;
static Scanner in=new Scanner(System.in);
public static void Gp(double hra,double da)
{
grossP=basic + (basic*(hra/100))+(basic*(da/100));
}
public static void NetPay()
{
netpay=grossP - (grossP*(15.0/100));
}
public static void display()
{
System.out.println("Emplyee no. "+empNo);
System.out.println("Gross Pay "+grossP);
System.out.println("Net Pay "+netpay);
}

public static void main()
{
System.out.println("Enter employee No. ");
empNo=in.nextInt();
System.out.println("Enter basic pay ");
basic=in.nextDouble();
System.out.println("Enter HRA% and DA%");
double h=in.nextDouble(),d=in.nextDouble();
Gp(h,d);
NetPay();
display();
}
}

In this post we have shared a java program which is mostly asked by students of computer science.

Explaining the code:

The provided Java code defines a class named Employee with static variables and methods for calculating gross pay, net pay, and displaying employee information. The class includes methods for computing gross pay (Gp) based on provided house rent allowance (HRA) and dearness allowance (DA) percentages, calculating net pay after deducting a fixed tax rate of 15%, and displaying employee details including employee number, gross pay, and net pay.

In the main method, it prompts the user to input employee number, basic pay, HRA percentage, and DA percentage. Then, it calculates gross pay using the provided allowances and basic pay, followed by computing net pay by deducting tax. Finally, it displays the employee’s details including the employee number, gross pay, and net pay.

This code snippet demonstrates basic concepts of Java programming, including class definition, static methods, user input using Scanner, mathematical calculations, and output display. However, it could be enhanced by incorporating encapsulation, error handling for invalid inputs, and clearer variable names to improve readability and maintainability. Additionally, separating concerns into different classes, such as Employee and PayCalculator, would enhance code organization and scalability.
