Kotlin Named and Default Arguments- FAQs
Named arguments are particularly useful when dealing with functions that have many parameters or when you want to make your code more self-explanatory. They help avoid confusion and errors when the parameter order is not immediately clear.
Default parameters are defined in Kotlin functions by providing default values directly in the function declaration. These default values are used when the caller of the function does not provide a value for a particular parameter.
Yes, you can mix default and non-default parameters in Kotlin functions. However, parameters with default values should be specified after non-default parameters in the parameter list.
Yes, you can combine named arguments with default parameters. This allows you to specify values for specific parameters by name and omit others, providing great flexibility in function calls.
When using named arguments, if you explicitly provide a value for a parameter that also has a default value, the provided value takes precedence over the default value.
Yes, you can override the default value of a parameter for a specific function call by providing a different value when calling the function.
You can specify a default argument for a nullable parameter by providing a default value that is also nullable. For example, you can use null as a default value for a nullable String? parameter.
Named and default arguments are not unique to Kotlin. They are features found in various programming languages, although the syntax and implementation details may vary. Other languages, such as Python and Swift, also support similar concepts.
