3. Exercise - Scanner

This exercise will help you become more familiar with the Scanner class.

Write a single class app that uses Scanner to ask the user to type in the value of an angle: Input

If the angle is less than 90, print out acute angle, e.g.: Acute Angle Output

If it is exactly 90, print out right angle, e.g.: Right Angle Output

If it is more than 90 but less than 180, print out obtuse angle, e.g.:, Obtuse Angle Output

If it is exactly 180, print out straight angle, e.g.: Straight Angle Output

If it is otherwise, print out reflex angle, e.g.: Right Angle Output

In IntelliJ, create a new Java Project called AngleProject.

Create a class called Angle.

Import the Scanner class; recall that this must be the first line in your file.

Add a main method to the class and in this method:

Create an object of the Scanner class.
Ask the user to enter an angle and store it (you can determine the variable type from the screen shots above).
Call the processAngle method (defined below) passing, as the parameter, the angle value that you just read in.

Create a private method, with a void return type and call it processAngle. It should accept one parameter of type int.

This method interrogates the parameter value and prints the type of angle it is to the screen (according to the screen shots above).

Run the app; does all work as expected?
