Scala评论 (Scala comments)

Comments are things that are readable by the programmer. They are added to the code to add an explanation about the source code. Commenting on a program to make it easier to understand by the programmer.

注释是程序员可以读取的东西。它们被添加到代码中以添加有关源代码的说明。对程序进行注释，使程序员更易于理解。

In Scala also comments are available. The comments in Scala are same as C++, Java and many other popular programming languages.

在Scala中，也提供注释。 Scala中的注释与C ++，Java和许多其他流行的编程语言相同。

There are two types of comments that can be added to a program:

可以将两种类型的注释添加到程序中：

Single-line comment
单行注释
Multiline Comment
多行注释

1)单行注释 (1) Single line comment)

It is the comment that has a span of an only single line. The line in which comment is started is commented.

该注释的跨度只有一行。开始注释的行被注释。

Syntax:

句法：

    // Single line code to be commented...

2)多行注释 (2) Multiline comment)

A multiline comment can span up to many lines based on its end literal. A multiline comment starts and ends with a literal and all the code inside that literal is treated as a comment.

根据多行注释的结束文字，它最多可以包含多行。多行注释以文字开头和结尾，该文字内的所有代码均被视为注释。

Syntax:

句法：

    /* 
Multiline
Code to be commented 
*/

Scala评论示例 (Example for Scala comments)

def main(args: Array[String]) {
//printing Hello world! - this is single line comment
print("Hello world!");
/*

Here, we are printing Hi friends!
