Scala評論 (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.

注釋是程序員可以讀取的東西。 它們被添加到代碼中以添加有關源代碼的說明。 對程序進行注釋，使程序員更易于理解。

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

在Scala中，也提供注釋。 Scala中的注釋與C ++，Java和許多其他流行的編程語言相同。

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

可以將兩種類型的注釋添加到程序中：

Single-line comment

單行注釋

Multiline Comment

多行注釋

1)單行注釋 (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.

該注釋的跨度只有一行。 開始注釋的行被注釋。

Syntax:

句法：

// Single line code to be commented...

2)多行注釋 (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.

根據多行注釋的結束文字，它最多可以包含多行。 多行注釋以文字開頭和結尾，該文字內的所有代碼均被視為注釋。

Syntax:

句法：

/* MultilineCode to be commented */

Scala評論示例 (Example for Scala comments)

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

Output

輸出量

Hello world!Hi friends!
