While using an ArrayList, I can't seem to figure out how to reset and re-apply the random color for each iteration of the for loop. I am trying to reset and apply my random color every time my XLeft position is changed. This is only a section of one class I am using, and my getMax() was defined by a Scanner input. Any suggestions?
import java.util.ArrayList;
import java.util.Random;
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.Rectangle;
public class BarChart {
private int width, height;
private ArrayList<Double> values = new ArrayList<Double>();
private Random generator = new Random();
int red = generator.nextInt(255);
int green = generator.nextInt(255);
int blue = generator.nextInt(255);
private Color randomColor = new Color(red, green, blue);
public BarChart(int aWidth, int aHeight) {
width = aWidth;
height = aHeight;
}
public void add(double inputValues) {
values.add(inputValues);
}
public double getMax() {
double max = values.get(0);
for (int i = 1; i < values.size(); i++) {
if ((values.get(i)) > max)
max = values.get(i);
}
return max;
}
public void draw(Graphics2D g2) {
int xLeft = 0;
double barWidth = width / values.size();
for (int i = 0; i < values.size(); i++) {
double barHeight = (values.get(i) / getMax()) * height;
Rectangle bar = new Rectangle(xLeft, height - ((int) barHeight),
(int) barWidth, (int) barHeight);
g2.setColor(randomColor);
g2.fill(bar);
xLeft = (int) (xLeft + barWidth);
xLeft++;
}
}
}
