Creating An Array
1.Declearing The Array.
2.Creating Array.
3.Putting Values Into The
Memory Location.
Declaration The Array

Type arrayname[];
int number[5];

Type []arrayname;
int [5] number;
Creation Of Array
Arrayname=new type[size];
For Example:Number=new int[5];
Initialization Of An Array
Arrayname[subscript]=value;
For example:
Number[0]=35;
Number[1]=20;
Number[2]=30;
Two Dimensional Array
int myArray[][];
myarray =new int[3][2]
