7. Write a Java program to perform employee payroll processing using packages. In the java file, Emp.java creates a package employee and creates a class Emp. Declare the variables name,empid, category, bpay, hra, da, npay, pf, grosspay, incometax, and allowance. Calculate the values in methods. Create another java file Emppay.java. Create an object e to call the methods to perform and print values.
💡Code:
Emp.java
package employee;
public class Emp {
private String name;
private int empID;
private String category;
private double basicPay;
private double hra;
private double da;
private double netPay;
private double pf;
private double grossPay;
private double incomeTax;
private double allowance;
public Emp(String name, int empID, String category, double basicPay) {
this.name = name;
this.empID = empID;
this.category = category;
this.basicPay = basicPay;
}
public void calculateHRA() {
if (category.equals("A")) {
hra = 0.5 * basicPay;
} else if (category.equals("B")) {
hra = 0.4 * basicPay;
} else {
hra = 0.3 * basicPay;
}
}
public void calculateDA() {
da = 0.1 * basicPay;
}
public void calculateNetPay() {
grossPay = basicPay + hra + da;
pf = 0.12 * basicPay;
incomeTax = 0.2 * grossPay;
netPay = grossPay - pf - incomeTax;
}
public void printPayroll() {
System.out.println("Employee Name: " + name);
System.out.println("Employee ID: " + empID);
System.out.println("Category: " + category);
System.out.println("Basic Pay: " + basicPay);
System.out.println("HRA: " + hra);
System.out.println("DA: " + da);
System.out.println("Gross Pay: " + grossPay);
System.out.println("PF: " + pf);
System.out.println("Income Tax: " + incomeTax);
System.out.println("Net Pay: " + netPay);
}
} EmpPay.java
package employee;
public class EmpPay {
public static void main(String[] args) {
Emp e = new Emp("John Doe", 123, "A", 20000.00);
e.calculateHRA();
e.calculateDA();
e.calculateNetPay();
e.printPayroll();
}}
