Arrays:
=======
variable ==> named container
	store the value
Syntax:
	datatype variable-name = value;
int x = 10;
x = 20;

Is it possible to store multiple values in one variable?
========================================================
ex: int a = 1,2,3,4; ==> Incorrect representation

Arrays:
=======
	==> Array is an object
	==> can be represented with an identifier/name
		to represent the memory storage
	==> is the collection of similar data items.
	ex: [1,2,3,4,5]
	[1.2f,2.3f,3.4f]
	==> array elements/items can store in heap memory.
	==> array can reserve with contiguous memory.
	==> Array elements/items can access with a positive index values.
		0 to n-1
	Syntax:
		array-name[index-value] ==> can helps to access the individual elements 

class A{
	int a = 100;
}
obj = A()
obj.a

Scanner
	nextInt()
	nextFloat()

Where arrays can use?
=====================
ICICI Bank{
	lacks of people ==> Subscribers of ICICI
}

Advantages:
===========
1) Optimize the code
5-students
	5-marks
stu1 = {s1,s2,s3,s4,s5}

Disadvantage:
=============
Array size cannot be dynamically change.


==> Arrays can be classified into three types:
================================================
	1) Single Dimensional Array
	2) Two Dimensional Array
	3) Multi-Dimensional Array

Single Dimensional Array
=========================
==> also called as "one dimensional arrays".
Syntax: (for declaration)
	1) datatype[] identifier;
	2) datatype []identifier;
	3) datatype identifier[];

JRE System Library
SRC

package Java_Arrays;

public class OneDimensionalArray {

	public static void main(String[] args) {
		// Declaring of character array
		
		char[] a1 = {'a','e','i','o','u'};
		// integer array declaration
		int []a2 = {1,3,5,7,9,9,7};
		// float array declaration
		float a3[] = {0.1f,0.2f,0.3f};
		
		// when the array is declared but not initialized:
		// by default the array elements can be fill with 0
		System.out.println(a1[1]);
		System.out.println(a2[3]);
		System.out.println(a3[0]);

	}

}

====================================
Instantiation of array definition:
==================================
Syntax:
	datatype[] array-name = new datatype[size];

==> default value for array element ==> 0 (integer array)
