- 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.

- 21. Which properties will extend a grid item so that it covers multiple rows and columns, specifically the area from row gridlines 3 to 5 and from column gridlines 1 to 3? Group of answer choices a. grid-row: 3/5; grid-column: 1/3; b. grid-row: 2/4; grid-column: 4; c. grid-column-start: 3; grid-column-end: 5; d. grid-column-start-end: 1/3; grid-row-start-end: 3/5;arrow_forward2. The Integer.parseInt () method requires a String argument, but fails if the String cannot be converted to an integer. Write an application in which you try to parse a String that does not represent an integer value. Catch the Number FormatException that is thrown, and then display an appropriate error message. Save the file as Try ToParseString.java.arrow_forwardCreate two linkedBag objects of type string in main. Place 5 strings in the first bag and five strings in the second bag. Then your code must test if the two linkedBag objects are equal or not. You must traverse both linkedBags and test each items to see if they are the same. Then you must display a message saying the two linkedBags are the same or different. Using Java compiler.arrow_forward
