Arrays:  


     Looking at an  array of integers

  int arrayName[];

    A second way in which arrays can be specified:

  int[]   array2;

    array2 = new int[10];   // allocated memory
                            // for an array of 
                            //  10 integers

    // the following code allows the amount of
    //  memory allocated to vary every time the
    //  the code would be executed.
    int size;
    size = SimpleInput.getIntNumber ("Enter  an int");
    array2 = new int [size];


    array2[3] = 7;
           ^
           |
        Subscript  

   Valid subscript range from 0 to Size-1

   int i;
   for ( i = 0 ; i < 10 ; ++i )
      {
        array2[i] = i * 2;
      }

Pos:  0  1  2  3  4  5  6  7  8  9
Val:  0  2  4  6  8 10 12 14 16 18

// Sum the values in an array


   int sum = 0;
   int i;
   for ( i = 0 ; i < 10 ; ++i )
      {
        sum = sum + array2[i] ;
      }
   System.out.println("The sum is: " + sum);
