Array Examples: Part 1
Learn with the help of examples to manipulate arrays for our benefit in this lesson.
We'll cover the following...
Coding example: 28
The following example will display how we can declare, initialize, and allocate memory for different types of variables. Read the comments written inside the example.

/*Introduction to array objectPrimitive data types are not objects created from a class. They are special data types built into the language.To build an array object we need to take help from primitive data types.The only exception is StringWhat features will distinguish array from primitive data types?Let us see to that problem*/public class ExampleTwentyEight {public static void main(String[] args){//an example of primitive data type//a variable is a container that contains a value or a primitive data typesint myAge = 54;System.out.println("An example of primitive data type : " + myAge);//in case of array we declare and allocate memory with a new keyword//the following array container holds a fixed number of value of data type int//the length of the array is established//here the length is 2, this container has 2 elementsint[] myBasket = new int[2];//each item or element has a corresponding numerical index that starts with 0myBasket[0] = 2;myBasket[1] = 3;//each element can be accessed by its corresponding numerical indexSystem.out.println("The first element of my basket : " + myBasket[0]);System.out.println("The second element of my basket : " + myBasket[1]);}}
Code explanation
The output gives us an idea about how we can treat these variables in a different way.
