Practice questions on Java Classes and Objects – Find Net Pay of an Employee

Define a class employee with the following specification :

• Members are : empno of type integer, ename of type String, basic, hr and da are of  type float, netpay of type float.
• Member functions :
• Calculate() : A function to find basix+hra+da with the float return type.
• havedata() : function to accept values for empno, ename, basic, hra, da and invoke calculate() to calculate netpay.
• dispdata() : function to display all the data members.

Solution

import java.util.*;

class EMPLOYEE
{
    int empno;
    String ename;
    float basic, hra, da, netpay;
     
    public float Calculate(){
        return basic+hra+da;
    }

    public void havedata(){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter Employee Number : ");
        empno=sc.nextInt();
        System.out.println("Enter Name : ");
        ename=sc.next();
        System.out.println("Enter Basic, HRA and DA : ");
        basic=sc.nextFloat();
        hra=sc.nextFloat();
        da=sc.nextFloat();
        netpay=Calculate();
    }
    

    public void dispdata(){
        System.out.println("Employee Number : "+empno);
        System.out.println("Employee Name   : "+ename);
        System.out.println("Basic   : "+basic);
        System.out.println("HRA     : "+hra);
        System.out.println("DA      : "+da);
        System.out.println("Net Pay : "+netpay);
    }
}

class EmpDetails
{
   public static void main(String args[])
   {
     EMPLOYEE ob=new EMPLOYEE();  
     ob.havedata();
     ob.dispdata();
   }
}

Save the above Program with “EmpDetails.Java” then compile it with the following commands:

javac EmpDetails.java  //to compile the code

java EmpDetails       // to run the code

Output is

Enter Employee Number :
105
Enter Name :
Sunny
Enter Basic, HRA and DA :
14000
5000
7500

Employee Number : 105
Employee Name   : Sunny
Basic   : 14000.0
HRA     : 5000.0
DA      : 7500.0
Net Pay : 26500.0
