declaring array of objects

Показать описание
Okay, let's dive deep into declaring and using arrays of objects in programming. This concept is fundamental in object-oriented programming and is crucial for managing collections of related objects efficiently.
**Understanding Arrays**
Before we delve into arrays of objects, it's essential to understand what arrays themselves are. An array is a data structure that stores a fixed-size, sequential collection of elements of the same data type. Think of it as a numbered list or a series of containers, each holding a value of the same kind.
Key characteristics of arrays:
* **Fixed Size:** Once an array is declared with a specific size, that size is generally fixed at the time of creation (some languages offer dynamic arrays, but the core concept remains).
* **Sequential Access:** Elements are stored in contiguous memory locations, allowing you to access any element quickly using its index (position in the array).
* **Same Data Type:** All elements in an array must be of the same data type (e.g., integers, strings, custom objects).
**Declaring Arrays of Objects**
An "array of objects" is simply an array where each element of the array is an object of a particular class. Instead of storing primitive data types like `int` or `string`, it stores instances of your own defined classes. This is incredibly useful when you want to manage multiple instances of a custom data type.
**General Syntax (Common Across Languages)**
The exact syntax for declaring an array of objects varies slightly depending on the programming language. However, the core concept remains the same. Here's a general representation:
Let's break this down:
* `ClassName`: This specifies the type of object that the array will hold. It's the name of the class you've defined (e.g., `Person`, `Car`, `Employee`).
* `arrayName`: This is the name you choose for your array. It's how you'll refer to the array later in your code.
* `[]`: The square brackets indicate that this is an array. ...
