Write, compile, and test the Comments class that uses the command window to display the following statement about comments: Program comments are nonexecuting statements you add to a file for documentation. Also include the same statement in three different comments in the class: each comment should use one of the three different methods of including comments in a Java class. Grading Write your Java code in the area on the right. Use the Run button to compile and run the code. Clicking the Run Checks button will run pre-configured tests against your code to calculate a grade. Once you are happy with your results, click the Submit button to record your score.

TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. 3. Write an application that reads the radius of a sphere then calculates and displays the circumference, volume and surface area. Use the following formulas, in which r represents the sphere’s radius. Print the output to four decimal places.Circumference = 2 π rVolume = 4/3 π r3Surface Area = 4 π r2 Hint: Section 3.5 of the textbook describes the many methods of the Math class and how they are used. The Math class also contains pre-defined constants like π. Search on the web for how you can use these. Testing: Include test exhibits for inputs that you choose. Make sure you check the results either with a calculator or some other independent source. Hint: Try Google!

TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. 1. Write an application that prompts for and reads the user’s first and last name (separately), then displays a string composed of the first four characters of the user’s last name, followed by the first two letters of the user’s first name, followed by a random number in the range of 10 to 99. Assume that the last name is at least four letters long. Similar algorithms are sometimes used to generate usernames for new computer accounts. Testing: If the inputs were “Michael” and “Jackson,” the output should look like “JackMi42.” Include several tests with different inputs, including your own name.
