Question

his assignment will help the student by:

• Create shapes using Java code
• Using and creating colors with Java
• Coding JFrames and using the Graphics g method
• Using Loops (to draw)

Your program will generate a drawing using java. You should draw an object that makes sense, not just spare shapes and colors.

• You must use at least 3 different shapes
• You must use at least 2 different fonts
• You must use at least 2 predefined java colors and one custom-made color
• You should use one loop to draw something, your choice, for loop or while loop

The program name should be Art .java if you use any other name you will get points deducted.

Students must always follow the JAVA Java coding standards for the class.
