Q. Define a class Employee having private members – id, name, department, salary. Define default and parameterized constructors. Create a subclass called “Manager” with private member bonus. Define methods accept and display in both the classes. Create n objects of the Manager class and display the details of the manager having the maximum total salary (salary+bonus)
Program:
import java.io.*;
class Emp{
private int id;
private double salary;
private String name,dept;
double total;
double sal=salary;
public Emp(){
id=0;
salary=0.0;
name="";
dept="";
}
public Emp(int id,double salary, String name, String dept){
this.id=id;
this.salary=salary;
this.name=name;
this.dept=dept;
}
public void accept() throws IOException{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter id of employee: ");
id=Integer.parseInt(br.readLine());
System.out.println("Enter name of employee: ");
name=br.readLine();
System.out.println("Enter salary of employee: ");
salary=Double.parseDouble(br.readLine());
System.out.println("Enter department of employee: ");
dept=br.readLine();
}
public double total(){
total=total+salary;
return total;
}
public void display(){
System.out.println("Emp Id: "+id);
System.out.println("Name: "+name);
System.out.println("Salary: "+salary);
System.out.println("Department: "+dept);
}
}
class Manager extends Emp{
private double bonus;
public void accept() throws IOException{
super.accept();
System.out.println("Enter Bonus of employee: ");
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
bonus=Double.parseDouble(br.readLine());
super.total=bonus;
}
public void display(){
super.display();
System.out.println("Bonus: "+bonus);
System.out.println("Total Salary: "+total);
}
}
public class sa1 {
public static void main(String[] args) throws IOException{
Manager[] m=new Manager[10];
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the number of employees: ");
int n=Integer.parseInt(br.readLine());
for(int i=0;i<n;i++){
m[i]=new Manager();
m[i].accept();
m[i].total();
}
for(int i=0;i<n;i++){
m[i].display();
System.out.println("---------------------------------");
}
double src=m[0].total;
int temp=0;
for(int i=1;i<n;i++){
if(src<m[i].total)
{
src=m[i].total;
temp=i;
}
}
System.out.println("The Employee having the maximum Total salary is :");
m[temp].display();
}
