Comments

- [Narrator] Comments in Kotlin are just like those in Java.…There are two basic forms, end of line…and block comments.…An end of line comment begins with two forward slashes…and lasts until the end of the line.…The block comment can span multiple lines.…It begins with a forward slash and an asterisk…and ends with an asterisk and a forward slash.…Everything in between the beginning…and the end of the comment is commented out.…

Unlike in Java, block comments can be nested,…meaning you can wrap an inner comment…with an outer one.…This can be handy when you need to comment out…a block of code that already contains comments.…Here is a meaningless function…with block comments already in it.…We can comment this whole entire block out…by simply putting another set…of block comments around it.…

In Java, you would have to remove the inner set…of comments in order to avoid errors.…
