This is the StatsArray class I needed to write for class. The StatsArrayGUI was provided, and can't be changed. When I complie my code, the GUI doesn't show. Just get a Java window icon, which displays/is nothing.

Here's my code.

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

public class StatsArray { //instance variables private int size; //how big is the array private int[] stats; // an array of integers //default constructor -overloaded method StatsArray() { size = 10; stats = new int[size] ; //instantiate the array called stats } 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 void fillArray() { /*fill the array with random numbers (int) in the range 0 - 100.*/ Random random = new Random(); for (int index = 0; index < size; index=index++) { stats[index] = random.nextInt(101); } } public int getSum() { int sum = 0; for (int index = 0; index < stats.length; index++) sum = sum + stats[index]; return sum; } public int getMax() { int maximum = Integer.MIN_VALUE; for(int index = 0; index < stats.length; index++) if(maximum < stats[index]) maximum = stats[index]; return maximum; } public int getMin() { int minimum = Integer.MAX_VALUE; for(int index = 0; index < stats.length; index++) if(minimum > stats[index]) minimum = stats[index]; return minimum; } public double getAverage() { return (double)getSum() / stats.length; } public int countValues(int lowRange, int highRange) { int count = 0; for(int index = 0; index < stats.length; index++) if((stats[index] >= lowRange) && (stats[index] <= highRange)) count++; return count; } public boolean isValueFound(int someNumber) { //check to see if someNumber is in the array boolean found = false; for (int index = 0; index < stats.length; index = index++) { if (stats[index] == someNumber) { found = true; return true;} } return found; } 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; } } public void sortBArray() { /*Here is another common sort algorithm. It sorts the array in ascending order. This is called a bubble sort. I have added it so that you can take a look at it.*/ 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; } } } }
