So I created this StatsArray.java with exception.

import java.awt.*;

import java.util.Random; //for our random number generator

import java.util.Scanner;

public class StatsArray

{

private int size; //how big is the array

private int[ ] stats; // an array of integers

//default constructor

StatsArray() {

size = 10;

stats = new int[size];

}

public void fillArray()

{

//fill the array with random numbers (int) in the range 0 - 100

Random random = new Random();

for(int i = 0; i < stats.length; i++)

{

stats[i] = random.nextInt(101) ;

}

}

public void fillArrayFromUser()

{

int i = 0;

String input;

do

{

try

{

System.out.println("Enter a value" + stats[i]);

Scanner Scan= new Scanner(System.in);

input = Scan.next();

int iValue = Integer.parseInt(input);

checkIfNegative(iValue);

stats[i] = iValue;

i++;

}

catch (NumberFormatException e)

{

System.err.println("An int was not entered");

}

catch (IllegalArgumentException e)

{

System.err.println("Illegal argument!");

}

}

while (i < stats.length);

}

public void checkIfNegative(int someValue)

{

if (someValue < 0)

{

throw new IllegalArgumentException( );

}

}

public void displayOut()

{

for(int i = 0; i < stats.length; i++)

{

System.out.println(stats[i]);

}

}

public void display(Graphics g)

{

int x = 50; //coordinates for displaying

int y = 40;

//display the array with position number

for(int i = 0; i < stats.length; i++)

{

g.drawString("Stats [" + i + "] = "+ stats[i], x, (y + 15 * i) );

}

}

public int getSum()

{

//add up all the values in the array

int total = 0;

for (int i = 0; i < stats.length; i++)

total = total + stats[i];

return total;

}

public int getMax()

{

//return the maximum value in the array

int maxValue = stats[0];

for (int i = 0; i < stats.length; i++){

if (stats[i] > maxValue)

maxValue = stats[i];

}

return maxValue;

}

public int getMin()

{

//return the minimum value in the array

int minValue = stats[0];

for (int i = 0; i < stats.length; i++){

if (stats[i] < minValue)

minValue = stats[i];

}

return minValue;

}

public double getAverage()

{

//return the average. must be a double

return (double)getSum() / stats.length;

}

public int countValues(int lowRange, int highRange)

{

//count how many numbers are >= lowRange and <= highRange

int count = 0;

for (int i = 0; i < stats.length; i++) {

if ( (stats[i] >= lowRange) && (stats[i] <= highRange) )

{

count++;

}

}

return count;

}

public boolean isValueFound(int someNumber) {

//check to see if someNumber is in the array

boolean found = false;

for(int i = 0; (i < stats.length && !found); i++) {

if (stats[i] == someNumber) {

found = true;

}

}

return found;

}

public void sortBArray() {

/*sort the array in ascending order - bubble sort*/

int tempValue;

for (int i = 0; i < (stats.length - 1); i++)

{

for (int j = (i + 1); j < (stats.length); j++)

{

if (stats[j] < stats[i])

{

tempValue = stats[i];

stats[i] = stats[j];

stats[j] = tempValue;

}

}

}

}

public void sortArray() {

/*sort the array in ascending order - selection sort*/

int tempValue;

int min;

for (int i = 0; i < (stats.length - 1); i++)

{

min = i;

for (int j = (i + 1); j < (stats.length); j++)

{

if (stats[j] < stats[min])

{

min = j;

}

}

tempValue = stats[min];

stats[min] = stats[i];

stats[i] = tempValue;

}

}

}

So now, how do I create my StatsArrayTester.java. So far, this is what I got.

import java.util.Scanner;

public class StatsArrayTester

{

public static void main (String[] args)

{

Scanner scanner = new Scanner(System.in);

StatsArray stats = new StatsArray();

System.out.println("Welcome to our StatsArray\n");

stats.fillArray();

}

}

Any help will be appreciated. Thanks
