The final picture is how the program run should look. So far here is my code to show you that I have attempted it.
import java.util.Random;
import javax.swing.JOptionPane;
import javax.swing.JTextArea;
public class NumberHistogram
{
// Declare the integer range
public static final int MAX_INT = 10;
public static final int MIN_INT = 0;
public static final int RANGE = 11;
public static void main(String[] args)
{
String output = "Number Value Count of Occurrences Histogram ";
// Prompt user and ask how many random values they want to generate
String input = JOptionPane.showInputDialog("How many random values do you want?");
int numValues = Integer.parseInt(input);
// Standard one-dimensional array to represent the integers from 0 to 10
int[] list = new int[RANGE];
// Use a random object within a loop to produce the random integer
Random generator = new Random();
for (int i = 0; i < numValues; i++)
{
int randNum = generator.nextInt(MAX_INT);
System.out.println(randNum); // useful to see the numbers generated
list[i] = randNum;
output += " " + i + " " + list[i] + " " + " |";
// print bar of asteriks
for (int j = 0; j < list[i]; j++ )
{
output += "*";
}
output += " " + i + " " + list[i] + " " + " |";
}
JTextArea outputArea = new JTextArea();
outputArea.setText(output);
JOptionPane.showMessageDialog(null, outputArea,
"Message", JOptionPane.INFORMATION_MESSAGE);
}
}
