BUILD SUCCESSFUL (total time: 1 minute 29 seconds)
Thanks
Here is the code
import java.util.*;
public class SmallestNumber
{
// default constructor
public SmallestNumber()
{
}
// make console reader
static Scanner console = new Scanner(System.in);
// program entry
public static void main(String[] args)
{
// get number of elements
int numOfElements = getTotalNumberOfElementsFromUser();
// get array of numbers
int[] numbers = getNumbers(numOfElements);
// find smallest number index
int minIndex = smallestIndex(numbers, numOfElements);
// print out total numbers
System.out.println( "You have total " + numOfElements + " elemnets");
System.out.println( "The numbers you entered are: ");
// print out numbers
for (int i =0; i < numOfElements; i++)
{
String seperator = ((i+1) < numbers.length) ? "," : ".";
System.out.print(numbers + seperator );
}
System.out.println("");
// print out smallest number amd index
System.out.print("Your smallest element is: " +
numbers[minIndex] );
System.out.println(" at index " + minIndex);
}
// get amd return number of elements
public static int getTotalNumberOfElementsFromUser()
{

do

if ( numOfElements <= 0 )
{
System.err.println( "Invaild input! Please try again."
);
}
}
while ( numOfElements <= 0 );
return numOfElements;
}
// get and return an array of numbers
public static int[] getNumbers(int numOfElements)
{
int[] numbers = new int[numOfElements];
for (int i = 0; i < numOfElements; i++)
{
System.out.print("Please enter number: ");

}
return numbers;
}
// return index of smallest number

{
int minIndex = 0;
