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!

Assume certain things to be true. points is the name of a variable that stores integer values, while textbox is the name of a textbox control. Implement the TryParse methods in an if-else statement that transforms the Text property of a pointsTextBox control to an int and stores the result in a points variable, as shown in the following example. If the conversion fails, an error message will be shown in a message box on the screen.

Q2:Assume that we have a Button object named btnPrint, and a method named print(). Write a statement that will cause the button to trigger a call to the print method.

Using C# in a visual studio form, Create an application. Add  a label and a button to the form. The button’s Click event procedure should add the  number 1 to the contents of a class-level Integer variable named intNumber and then  display the variable’s contents in the label. Code the application. Be sure to enter the  three Option statements above the Public Class clause. Save the solution and then start  and test the application. Next, change the class-level variable to a static variable.
