问在java中使用HSB创建平滑渐变

EN

Pseudocode{
int[50] arr={1,2,3...}
for(int i:arr)
    rect.color=getColor(i,arr.length)
}

private static Color getColor(int value, int length){
    float h=((float)value/(float)length);//goes from 0-1
    System.out.println(value+" "+length+" "+h);
    java.awt.Color rgb=java.awt.Color.getHSBColor(h,255,255);
    int r=rgb.getRed();
    int g=rgb.getGreen();
    int b=rgb.getBlue();
    System.out.println(rgb+" "+r+" "+g+" "+b);
    return new Color(r,g,b);//greenfoot.Color, not java.awt.Color
}
