scala 字符串占位符

A string is a sequence of characters and it can contain multiple lines, for this, the string uses the newline character \n. And, we can separate each newline into a string and store them as a list of strings.

字符串是字符序列，可以包含多行，為此，字符串使用換行符\ n 。 并且，我們可以將每個換行符分隔成一個字符串，并將它們存儲為字符串列表。

For this purpose, we can use some methods that are built-in in the Scala language. The logics rest the same, storing all contents in a string until a newline is encountered and after the newline, the contents till the next are stored in the second string of the sequence and so on.

為此，我們可以使用Scala語言內置的一些方法。 邏輯保持不變，將所有內容存儲在字符串中，直到遇到換行為止；在換行之后，直到下一行的內容都存儲在序列的第二個字符串中，依此類推。

Methods that are used,

使用的方法

string.split('char'):

string.split('char') ：

This function splits the string after the occurrence of the specified character. This means that when the character occurs the string will get split.

此函數在出現指定字符后分割字符串。 這意味著當字符出現時，字符串將被分割。

toVector:

toVector ：

This method stores this split string into a list that is to be returned.

此方法將此拆分字符串存儲到要返回的列表中。

Program:

程序：

object MyClass {def convertStringToSeq(s: String): Seq[String] =s.split("\n").toVector def main(args: Array[String]) {val str = "Hello!\nthisis\nInclude Help"val conlist = convertStringToSeq(str)println(conlist)}}

Output

輸出量

Vector(Hello!, thisis, Include Help)
