=============================

Arrays - to allow multiple data values to be
   stored using a single variable name.

int   array1[];
int[] array2;

array1 = new int[10];

int array3[] = new  int [10000];

int size = 500;
//size = SimpleInput.getIntNumber("Enter an integer");

array2 = new int [size];


To use an array, we again use the [] operator to
  specify a position in the array.

array1 [3] = 574;

For an array of size N, the valid "subscripts"/"positions"
   range from 0 to N-1

int i;

for (i = 0 ; i < 10 ; ++i)
  {
   array1[i] = 0;
  }

for (i = 0 ; i < array1.length ; ++i)
  {
   array1[i] = 0;
  }

for (i = 0 ; i < array3.length ; ++i)
  {
   array3[i] = SimpleInput.getIntNumber("Enter an integer");
  }

for (i = 0 ; i < array1.length ; ++i)
  {
   System.out.println ("Array1[" + i + "] is " +
                        array1[i]);
  }
