## 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：

1.  Single-line comment
    
    单行注释
2.  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**)** ###

object MyClass {
        
          def main(args: Array[String]) {
        
             //printing Hello world! - this is single line comment
             print("Hello world!");
             
             /* 
             This is multiline comment - 
             Here, we are printing Hi friends!
             */
             print("Hi friends!");
          }
       }

**Output**

**输出量**

Hello world!Hi friends!
