In Kotlin, you can provide default values to parameters in function definition. If the function is called with arguments passed, those arguments are used as parameters. However, if the function is called without passing argument(s), default arguments are used. ...
In some scenarios, we may want the default implementation to always return a constant value and ignore the input parameter. In this case, in the default lambda expression,we can use underscores for the parameters we don’t need,for example: fun greeting3(name: String = "Baeldung", buildMess...

Numberis:99andCharacteris:Z Kotlin Named Arguments In the above examples we have learned how we can set default values for the parameters. In the second example we learned that we can call the function while passing few of the values, we have made the function call like this in the second...
We can also define the default parameters in the function definition itself. The program below is equivalent to the one above. #include<iostream>usingnamespacestd;// defining the default argumentsvoiddisplay(charc ='*',intcount =3){for(inti =1; i <= count; ++i) {cout<< c; ...
Optional parameters can also be used in the default constructor, so you could get many overloads in a single declaration. Custom views are a special case, because they need more than one constructor to work properly in Java, but I´ll be covering this in next article. ...
Kotlin DSL is now the default for new Gradle builds. From now on it will be the default option in the plugins and documentation.
Using Kotlin Default Parameter Values when JSON value is null and Kotlin parameter type is Non-Nullable #130 In this case, paramDef.isOptional returns true if we have default parameters. Then we do...
I was surprised by the behavior of Jackson+Kotlin with respect to primitive parameters that have default values. It seems like those default values are ignored, and zero is used instead. Here's an example: class Main private constructor(...
