FlagDrawer: Pass level

You must complete this part even if you want to do the Challenge level.

Assumptions:

• The exact colours of the symbols will be difficult to match; It is fine to use the standard colours: red, green, blue, orange, etc. (See the Java Documentation on Color to find out what standard colors are available, but you can use more accurate colours if you wish.)

Instructions and Tips

• Images of the symbols required in this assignment are available in the Assig1 folder you downloaded.
• You can find lots of details, including the correct dimensions and colours, of flags from http://www.crwflags.com/fotw/flags/
• You may not use the UI.drawImage, or UI.drawString methods!
• You must use the TOP and LEFT constants.
• Details for each symbol can be found in the comments above the relevant methods in the code.
• You can use Color.green.darker() to use a darker green.
• You can use fillArc to draw parts of circles.
• The sizes are in pixels. Do not test your methods with sizes that are below 100. Test each method with various sizes.

Write methods to draw:

• The flag of Benin
• The flag of Greenland
• The Czech flag.

You must use the fillArc method from the UI library to draw the Czech flag.
