Description

In this exercise, you are tasked to modify the recursive method, drawFractalTree$(),$ in the TreePanel class so that a fractal tree with four branches at each node will be drawn.

Project Template

The project template for this graded task can be downloaded here.

Instructions

The run the program, create a new instance of FractalTree.

The current implementation of the drawFractalTree$()$ method draws the tree with three branches at each node oriented at $20$ degrees, $0$ degrees and $-20$ degrees relative to the node by three recursive calls.

Modify the implementation of the method so that it draws the tree with four branches at each node orientated at $30$ degrees, $15$ degrees, $-15$ degrees and $-30$ degrees relative to the node by four recursive calls.

You will need to change the fourth parameter for each of the four recursive calls to the drawFractalTree$()$ method to complete this task.

Submit ONLY the codes for the recursive calls. The remaining codes given in the drawFractalTree$()$ method must not be submitted.
