Define a class to accept values into a double array of size 20 and print the range of the array, range is the difference between the largest and the smallest elements of the array
Solution:
import java.util.*;
class Diff
{
public static void main (String args[])
{
double a[]=new double[20];
Scanner sc = new Scanner(System.in);
for(int i=0; i< 20; i++)
{
System.out.println("Enter the "+(i+1)+" element:");
a[i]=sc.nextDouble();
}
double max=a[0], min=a[0];
for (int i=0; i < a.length; i++)
{
if(a[i]>max)
max=a[i];
if(a[i]< min)
min=a[i];
}
System.out.println("The largest element in the array is :" + max);
System.out.println("
The smallest element of the array is :" + min);
System.out.println("
The range of array is : " + (max-min));
}
}
