Create an image in memory
int width=60, height=20;
BufferedImage image = new BufferedImage (width, height, bufferedimage.type_int_rgb);

Get Graphics context
Graphics g = image.getgraphics ();

Generate Random Class
Random Random = new Random ();

Set Background color
G.setcolor (Getrandcolor (200,250));
G.fillrect (0, 0, width, height);

Set font
G.setfont (New Font ("Times New Roman", font.plain,18));
