2A

For this problem we are going to draw a "rainbow"

Getting Set Up

• You will need some of the graphics classes in your project. You will need to import the necessary classes into your project.

Project specification

Complete the RainbowComponent class. The application will draw rainbow will starting at (0,0). The colors will be displayed in rectangles rather than arcs. Each rectangle has a width of 100 and a height of 20. There are 7 rectangles. The colors of the first 5 should be made with the pre-defined colors in the Color class. Use red, orange, yellow, green, and blue in that order. The next color is indigo and has RGB values (75, 0, 130). The last rectangle is violet with RGB values of (143, 0, 255). You will need to construct Color objects using these values.

This is what the result will look like:

2B

Draw the word TWO using the Line2D.Double and Ellipse2D.Double classes in the Java library.

Make a project and create a class called TwoComponent to do the drawing. There is no starter file this time. But a TwoViewer class is provided

Your drawing should follow these specifications.

• Each letter is 40 pixels wide and 50 pixels height
• There is a 10 pixel gap between letters
• The upper left hand corner of the T is at (20,50)
• Draw the T in red. Use the predefined color in the Color class
• Draw the W in blue. Use the predefined color in the Color class
• Fill the ellipse for the O (Do not draw it). Use a custom color where red is 200, green is 255, and blue is 10.

It is a good idea to figure out the coordinates of each letter before starting to draw. Trial and error is not efficient here.

2C

In this application, you will draw a target consisting of three concentric circles

Follow these specifications

• The center is at 100, 100
• The largest circle is red with a radius of 45 (Use Color.RED)
• The second circle is white with a radius of 30. (Use Color.WHITE)
• The smallest circle is red again with a radius of 15. (Use Color.RED)
