Details: Create a class called Power that computes the value of base exponent. The class should have one recursive method: • public static int power(int base, int exponent) – Which computes the value of base exponent using recursion, returning the result. The recursion step should use the following relationship base exponent = base x base exponent - 1 and the termination condition should occur when exponent is equal to 1, because base 1 = base NOTE: For the power method, assume the exponent parameter value is always greater than 0. Create a second class called PowerTest that contains the main method, and tests the Power.power method. The test class does not need to ask for input from the user of the class, nor does it need to do any additional error checking. Upload both source files to Blackboard. Note: Ensure that your program is properly formatted and it follows all Java naming conventions.arrow_forwardclassname.py -> using "sys.argv" ● Create a program called classname.py. The program should define a class called person that has one method called hello, and one attribute called name, which represents the name of the person. ● The hello method should print the following string to the screen: ‘My name is ____ and I am a _____’ where: ○ The first blank should be the name attribute ○ The second blank should be the name of the class ○ The above blanks should NOT be manually printed (ex. print(‘My name is Greg and I am a person’)) ● After defining the class, there are three things you must do: 1. Instantiate an object of the class 2. Run the hello method of the instantiated object a. (e.g., Greg.hello()) 3. For grading purposes, you must also print the name of the class so I can be sure you’ve created a class a. (The expected output is )arrow_forward
