Description of Array

Array is a collection of like-typed variables referred to by a common name. It allows for efficient and organized storage and manipulation of data in different programming languages. An array can contain values or objects of various types, including strings, integers, and objects of custom classes.

Features

• Arrays in Java:

  • Arrays are dynamically allocated and can be of varying sizes.
  • Examples of array implementations include:

    // Array of objects
    Student[] arr = new Student;
    arr = new Student(1, "aman");
    arr = new Student(2, "vaibhav");
    arr = new Student(3, "shikar");
    arr = new Student(4, "dharmesh");
    arr = new Student(5, "mohit");
    

• Arrays in PowerShell:

  • Arrays can be defined using the @() syntax.
  • Example:

    $data = @()
    $data = @('Zero', 'One', 'Two', 'Three')
    $data | Get-Member  // to get the type information
    

• Arrays in SAS:

  • Array elements can be referenced using subscripts and can include character or numeric fields.
  • Example:

    data array1;
    set basefile;
    array tots(14) tot1-tot14;
    do i = 1 to 14;
    if tots(i) = 0 then tots(i) = . ;
    end;
    drop i;
    run;
    

Key Aspects

• Common Use Cases: Arrays are advantageous when dealing with a series of similar data elements that need to be processed or manipulated together.
• Ease of Access: Elements in arrays can be accessed easily using their indexes.
• Variable Types: Arrays can hold elements of different types, including integers, strings, and object references.
• Dynamic Allocation: Arrays can be dynamically allocated, making them versatile for handling varying amounts of data.
• Indexing: Arrays provide efficient access to individual elements through their indexes, making data manipulation simpler.
