1. Copy the plant , MapleTree, Tulip, and Simulator classes into Eclipse or NetBeans.
2. Compile and run the example to ensure that the code has been copied correctly.
3. Add a new class called Rose that will represent a rose. Use the Plant base class and implement all of the required methods.
4. Add your new class into the simulator and run the application.
5. Include screen shot(s) showing successful execution of the program.
