Average salary of the employee


    This code will implement the average salary of the employee with some conditions using java8.


              1.  We need to create the first   Employeedata class.

             2.   Then we  will write a mail class  for  average 



          Employeedata  class 



 


    

  

Employeeavg   class


import java.util.ArrayList;

import java.util.List;

import java.util.stream.Collectors;


public class EmployeeAvg {

 public  static  void  avgEmp() {

       

Employeedata  E1=new Employeedata(122 ,23 ,"Tuku" ,300000 );

               

Employeedata  E2=new Employeedata(122 ,23 ,"chuto",40000.0 );


Employeedata  E3=new Employeedata(122 ,23 ,"Nathan",500000 );

         

Employeedata  E4=new Employeedata(122 ,23 ,"Matham",600000 );

           

             

       

  List<Employeedata>  employees=new ArrayList<>();

       

        employees.add(E4);

        employees.add(E2);

        employees.add(E1);

        employees.add(E3);

         

        

double averageSalary = employees.stream().

filter(x ->x.getSalary()>50000)

                        .mapToDouble(Employeedata::getSalary)

                        .average()

                        .orElse(0.0);

        

System.out.println("Average salary: " + averageSalary);


double averageSalarys = employees.stream().collect(Collectors.averagingDouble(num -> num.getSalary()));

       

 System.out.println("SimpleAverage salary: " + averageSalarys);

       

      //Another  way of averaging

       

double averageSalarym = employees.stream().

filter(x->x.getSalary()>50000).collect(Collectors.

averagingDouble(num -> num.getSalary()));

                     

              

 System.out.println("Average salary: " + averageSalarym);        

   

                             

      }

public static void main(String [] args)

      {

  avgEmp();

     

    }

       

       


}





 import java.util.Objects;


public class Employeedata {


 private int id;

 private int age;

 private String name;

 private double  salary;

 

 public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public double getSalary() {

return salary;

}

public void setSalary(double salary) {

this.salary = salary;

}

@Override

public String toString() 

{

 return "Employeedata [id=" + id + ", age=" + age + ",       name=" + name + ", salary=" + salary + "]";

        }

@Override

public int hashCode()

         {

return Objects.hash(age, id, name, salary);

}


@Override

public boolean equals(Object obj) {

if (this == obj)

return true;

if (obj == null)

return false;

if (getClass() != obj.getClass())

return false;


Employeedata other = (Employeedata) obj;

return 

age == other.age && id == other.id && Objects.equals(name, other.name)&&Double.doubleToLongBits(salary) == Double.doubleToLongBits(other.salary);

}



public Employeedata

(int id, int age, String name, double salary) {

super();

this.id = id;

this.age = age;

this.name = name;

this.salary = salary;

}

}



Program  output :



Average salary: 466666.6666666667

SimpleAverage salary: 360000.0

Average salary: 466666.6666666667
