double precision floating point

[James Jones]

hi, i am not sure how to make this an array of double precision floating point.....i am not sure what that means...can some1 help me out please...
thanks

 
 public class ArrayDemo
 {
     public static void main(String[] args)
     {
         int[] anArray;        // declare an array of integers
         anArray = new int[10];// create an array of integers
         // assign a value to each array element and print
         for (int i = 0; i < anArray.length; i++)
         {
             anArray[i] = i;
             System.out.print(anArray[i] + " ");
         }
         int minValue = anArray[0];
         int maxValue = anArray[0];
         int sum = 0;
         //Loop through the array to find the min, max and sum of all array elements
         for (int i = 0; i < anArray.length; i++)
         {
             minValue = java.lang.Math.min(minValue, anArray[i]);
             maxValue = java.lang.Math.max(minValue, anArray[i]);
             sum += anArray[i];
         }
         //print out the values
         System.out.println("\nminValue :" + minValue);
         System.out.println("maxValue :" + maxValue);
         System.out.println("sum :" + sum);
         //divide the sum by the no of array elements to get the mean
         float meanValue = (float)sum/anArray.length;
         System.out.println("meanValue :" + meanValue);
     }
 }

The Java type "float" is also called "single-precision floating point." The Java "double" is the double-precision version you're looking for.
Now, in your case, you've got an array of "int". You want an array of "double" instead -- is that all?
