5. Arrays

  Arrays is basically a container whhich can store a values (or) sequence of numbers,values,character itself.
Each item is an array is called an element is accessed by its numerical index.As shown in the preceeding illlustration,always numbering begins with zero.

 Let see an example:

package test package;
public class Array Demo
{
 public static void main(string [] args )
  {
// declares an array of integers
 int [] an Array;
// allocates memory for 10 integers
  an Array = new int [10];
// initialise first element 
  an Array [0] = 100;
initialise second element
  an Array [1] = 200;
// and so forth
  an Array [2] = 300;
  an Array [3] = 400;
  an Array [4] = 500;
  an Array [5] = 600;
  an Array [6] = 700;
  an Array [7] = 800;
  an Array [8] = 900;
  an Array [9] = 1000;

 sytem.out.println("Element at index 0 :" + anArray [0] 0;
 system.out.println("Element at index 1 :" + anArray [1] );
 system.out.println("Element at index 2:" = anArray [2] );
 system.out.println("Element at index 3:" + anArray [3] );
 system.ou.println("Element at index 4:" + anArray [4] );
 system.out.println("Element at index 5:" + anArray [5] );
 system.ou.println("Element at index 6:" + anArray [6] 0;
 system.out.println("Element at index 7:" + anArray [7] );
 system.out.println("Element at index 8:" + anArray [8] );
 system.out.println("Element at index 9:" + anArray [9] );
 system.out.println("Element at index 10:" = anArray [10] );
   }
}

Output:
  Element at index 0 : 100
  Element at index 1 : 200
  Element at index 3 : 300
  Element at index 4 : 500
  Element at index 5 : 600
  Element at index 6 : 700
  Element at index 7 : 800
  Element at index 8 : 900 
Element at index 9 : 1000
