What is control variable in a switch statement?
control statement switch case switch statement allows a variable to be tested for equality against a list of values. The switch statement is a multiway branch statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression.

Can a switch statement be the only thing in a method?
If you refactor such that the switch statement is the only thing in a method, and each entry in the switch statement calls only another method, then the state for each case and each method can usually be grouped into its own subclass. As a bonus you’d get your cyclomatic complexity down
When to replace conditional with polymorphism in switch statement?
If a switch is based on type code, such as when the program’s runtime mode is switched, use Replace Type Code with Subclasses or Replace Type Code with State/Strategy. After specifying the inheritance structure, use Replace Conditional with Polymorphism.
How are switch statements used in object oriented code?
You have a complex switch operator or sequence of if statements. Relatively rare use of switch and case operators is one of the hallmarks of object-oriented code. Often code for a single switch can be scattered in different places in the program. When a new condition is added, you have to find all the switch code and modify it.
