- What is the best reason to make a method be a static method? A. When the method does not make use of any of the class variables. B. When it includes a reference to a static variable. C. When we want to guarantee that it is a public method. D. Static methods should not be used in object oriented languages.Can you use it in a scanner so i can copy paste please. Part 1 A regular triangle is one for which all sides are congruent and all interior angles. Create a class RegularTriangle with a field side (int) Create a constructor which accepts an int parameter and will assign the parameter to field side Create assessor and mutator for this class Create a method getPerimeter() which should return 3*side; Part 2 in the constructor, add a logic that if the input parameter is less than 5 then set the side to 5, if it is >10 then set the side to 10, otherwise set the side to the input value.

It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter.

- Implement the below pseudo-code in a Java program using a while loop and aswitch-case statement. The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…We invoke, or call, another method when we want to execute it. The invoked code is not defined in the program we write, rather it is part of the System object which is part of the Java standard class library. Hence, we can call it. Example: println method. True or falseobject-oreinted programming. need the full code together with the comments.
