In this video, Doug Winnie demonstrates how you can customize a function by passing in a value using a function parameter. Function parameters are giving a unique variable name that is used during the life of the function, and then can be used throughout the function code.
- [Narrator] When we have a function or method,…we can accept values to help define how it works.…We have one in our code here that we can customize,…by setting in a value inside to change how it works.…There are two changes I want to make.…The first is to change how we display…the score in the console.…Right now, we have it only happening…when we change the score.…As we have learned from functions,…we can group commonly used code using a function name.…Displaying the score is a common action.…
It doesn't make sense to have it just…happen in one place, so let's fix that.…We need to create a new method that will display the score.…Let's create a display score function…at the bottom of our code.…public static_void displayScore…We can then move the System.out statement from the check…score function, and put it in the display score function.…
Now we can call that in more than one place.…We can call a display score from the main constructor,…and the changed score method.…We can see how the score changes throughout the game.…
