The enter feed symbol is different in different operating systems, see below:

In the Unix system, there is only "" or "\ n" at the end of each line; in the Windows system, the end of each line is "", that is, "\ r\ n"; in the Mac system, the end of each line is "", that is, "\ r".

The replace () method is used to replace some characters in a string with other characters, or to replace a substring that matches a regular expression.

Grammar

StringObject.replace (regexp/substr,replacement)

Parameter description

Regexp/substr is required. A RegExp object that specifies the substring or the schema to replace.

Note that if the value is a string, it is treated as an immediate amount of text pattern to retrieve, rather than being first converted to a RegExp object.

Replacement is required. A string value. Specifies the function that replaces the text or generates the alternate text.

Return value

A new string is obtained after replacing the first match or all matches of regexp with replacement.

Line Terminator: a line Terminator is a sequence of one or two characters that marks the end of a line of input character sequences. The following code is recognized as a line Terminator:

New line (newline) character ('\ n'),

The carriage return followed by the new line character ("\ r\ n"),

A separate carriage return ('\ r'),

The next line of characters ('\ u0085'),

Line delimiter ('\ u2028') or

Paragraph delimiter ('\ u2029).

Therefore, the most guaranteed way to consider the line closing symbol and its escaped form is

Str.replaceAll ("(\ n |\ r | (\ r\ n) | (\ u0085) | (\ u2028) | (\ u2029))", "")
