Program to define a class 'employee' with data members as empid, name and salary. Accept data for 5 objects using Array of objects and print it.

This program demonstrates you the array of objects. Array of object is the collection of objects of the same class. The given syntax will define an array of reference therefore assign object to individual reference in the array to declare the array of object. The syntax to define array of object is:
<class-name>  <array-name> [size];

For example, the following statement will define an array of object having size 6 references to the class Box.
Box  b[6];

For creating an array of objects (allocating memory) you have to write down the following statements
for (int i=0; i<6; i++) {
 b[i]  = new  Box();
 // Assigning object to individual reference in the array.
}

PROGRAM
import java.util.Scanner;

public class Employee {

 int empid;
 String name;
 float salary;
 
 public void getInput() {
 
  Scanner in = new Scanner(System.in);
  System.out.print("Enter the empid :: ");
  empid = in.nextInt();
  System.out.print("Enter the name :: ");
  name = in.next();
  System.out.print("Enter the salary :: ");
  salary = in.nextFloat();
 }
 
 public void display() {
  
  System.out.println("Employee id = " + empid);
  System.out.println("Employee name = " + name);
  System.out.println("Employee salary = " + salary);
 }
 
 public static void main(String[] args) {
 
  Employee e[] = new Employee[5];
  
  for(int i=0; i<5; i++) {
   
   e[i] = new Employee();
   e[i].getInput();
  }
  
  System.out.println("**** Data Entered as below ****");
  
  for(int i=0; i<5; i++) {
   
   e[i].display();
  }
 }
}

  8. The best way to learn is to learn by doing. Go for a full program that does a task you wanted to do on a computer in the past, work on it, and when you are finished you will have learned a lot and you will have a useful (or at least entertaining) program which is far better than some toy program demonstrating lists.best laptop for programming
