Basic concept of Array in Java Program Part 1

 An Array is a group of like-typed variables that are referenced by a common name. 

                                                      OR

 An Array is the collection of Homogeneous or Similar data-type. 

Example 1

                                  // Use of integer in array 

class Array

{

    public static void main(String args[])

    {

        int[] A = new int[5] ;

        A[0] = 7 ;

        A[1] = 2 ;

        A[2] = 3 ;

        A[3] = 1 ;

        A[4] = 5 ;   

        System.out.println(" The value is " + A[2]) ;

        System.out.println(" The value is " + A[4]) ;

    }

}

Example 2

                                                // Addition in Array

class Array

{

    public static void main(String args[])

    {

        int[] A = new int[5] ;

        A[0] = 7 ;

        A[1] = 2 ;

        A[2] = 3 ;

        A[3] = 1 ;

        A[4] = 5 ;   

        int x = A[1] + A[4] ;        

        System.out.println(" The value is " + x) ;      

    }

}

Example 3

                                       // Use of String in array 

class Array

{

    public static void main(String args[])

    {

        String d[] = {"Mon" , "Tue" , "Wed" , "Thurs" , "Fri" , "Sat"} ;       

        System.out.println(d[0]) ;

        System.out.println(d[2]) ;

    }
