Array of objects declaration

The following syntax is used to declare an array of objects,

class_name array_name[] = new class_name[SIZE];

C# example of array of objects

using System;

namespace ExampleArrayOfObjects {
  // Class definition
  class Student {
    //private data members
    private int rollno;
    private string name;
    private int age;

    //method to set student details
    public void SetInfo(string name, int rollno, int age) {
      this.rollno = rollno;
      this.age = age; = name;

    //method to print student details
    public void printInfo() {
      Console.WriteLine("Student Record: ");
      Console.WriteLine("\tName     : " + name);
      Console.WriteLine("\tRollNo   : " + rollno);
      Console.WriteLine("\tAge      : " + age);


  class Program {
    static void Main() {
      //creating array of objects
      Student[] S = new Student[2];

      //Initialising objects by defaults/inbuilt 
      S[0] = new Student();
      S[1] = new Student();

      //Setting the values and printing first object
      S[0].SetInfo("Herry", 101, 25);

      //Setting the values and printing second object
      S[1].SetInfo("Potter", 102, 27);



Student Record:
        Name     : Herry
        RollNo   : 101
        Age      : 25
Student Record:
        Name     : Potter
        RollNo   : 102
        Age      : 27

In the above example, we created a class for student and created array of objects to read, print the details of the students.
