Splitting string into array of substrings in Julia – split() and rsplit() Method

The split() is an inbuilt function in julia which is used to split a specified string into an array of substrings on occurrences of the specified delimiter(s).

Syntax:
split(str::AbstractString, dlm; limit::Integer, keepempty::Bool)
or
split(str::AbstractString; limit::Integer, keepempty::Bool)

Parameters:

• str::AbstractString: Specified string.
• Dlm: Specified delimiter.

Below arguments are optional:

• limit::Integer: It is the maximum size of the result. It’s default value is zero (0).
• keepempty::Bool: It says whether the empty fields should be kept in the result or not. Its Default value is false.

Returns: It returns an array of substrings of the specified string.

Example:

# Julia program to illustrate
# the use of String split() method

# Splitting of the specified strings
Println(split("Gee.ks", "."))
Println(split("Geeks, for, Geeks", ", "))
Println(split("GFG-gfg", "-", limit = 1))
Println(split("GFG-gfg", "-", limit = 2))

Output:

String rsplit() method

rsplit() method works exactly like split() method but starting from the end of the string.

Syntax:
rsplit(s::AbstractString; limit::Integer, keepempty::Bool)
or
rsplit(s::AbstractString, chars; limit::Integer, keepempty::Bool)

Parameters:

• str::AbstractString: Specified string.
• chars: Specified characters.

Below arguments are optional:

• limit::Integer: It is the maximum size of the result. It’s default value is zero (0).
• keepempty::Bool: It says whether the empty fields should be kept in the result or not. Its Default value is false.

Returns: It returns an array of substrings of the specified string.

Example:

# Julia program to illustrate
# the use of String rsplit() method

# Splitting of the specified strings
Println(rsplit("Gee.ks", "."))
Println(rsplit("Geeks, for, Geeks", ", "))
Println(rsplit("GFG-gfg", "-"; limit = 1))
Println(rsplit("GFG-gfg", "-"; limit = 2))
Println(rsplit("G-F-G-g-f-g", "-"; limit = 4))

Output:
