Question

The flags of many of the world’s nations consist of 3 colored bars displayed either vertically or horizontally; two examples are shown below: flag of France flag of Hungary Choose a style (either the French or the Hungarian) and write a Java program that can draw the flags of three nations that use that (vertical or horizontal) three-color style in a window when the user clicks a button with the country’s name; the window illustrated below (with fake country names, other than France) is an example of what you are trying to create: Your flag should change size with the window – in other words, don’t just use g.fillRect() calls – instead, set up JPanels and set their background colors
