CIS 1068 Assignment 5 practice with static methods and strings Due: February 24 60 points description Please download this zipped Eclipse project. Unzip the project, and import it into Eclipse by choosing File -> Import -> Existing Projects into Workspace. Open the project and its included source file StringPractice.java. You'll find that it contains several methods that have not yet been finished. For now, the methods contain only a placeholder return value so that the code will compile. Fill in your own implementation. Do not modify any other files in the project. You do not have to write a main() to test your code. Though it may not be obvious, all of the test code has been written for you. If you're curious, you can find it by looking at the file StringPracticeTest.java included in the same directory as the code you need to complete. These tests use the popular JUnit testing framework. For now, you are not required to understand how they work. If you're curious, by all means look, but please do not modify the contents of this file. In order to test your methods using the provided tests, click on the StringPracticeTest.java file, and the click the run button. Initially, you'll see a red bar, indicating that not all of the tests have passed. Each of your functions whose tests did not pass will have an X through its name. Eventually, you'll have perfectly debugged code, and the bar will turn green. It's highly recommended that you use short helper methods to help program other methods. For example, you might use your isFace() method in the more complicated methods involving "face cards". Similarly, you might consider using the reversed() method from this assignment in your your sameInReverse() method
