Convert a string to array in Ruby using split method

The split() function can be used in Ruby to convert a string to an array by following the defined pattern. It is an easier way to convert the string to an array. Ones can alter a string into multiple substrings by using this method.

In addition, a string can be cut into individual segments in this manner. You can split the string into parts that are based on words, spaces, and characters.

Syntax

array= string.split( pattern, limit) public

Parameters

• pattern: It can either be a string or a regular expression.  If the pattern is a string or regExp, a string will be subdivided where this pattern matches.
• limit: It shows the maximum number of entries allowed in the array.

Return value

array: An array of sub-string(s) will be returned as per the defined parameters.

Explanation

In the below-mentioned example, we are defining a code that will divide the string parts based on the white spaces between words.

string1 = "We are using a split method for converting a string into parts"
print string1.split()

• Line#1: Defining a string.
• Line#2: Invoking string1.split() method in ruby to split a string into an array of sub-strings with the default termination character is space.

Output

We can also split the string into an array of individual characters by using the following code.

string2 = "AlgoIdeas"
print string2.split("")

• Line#1: Defining a string with "AlgoIdeas" as value.
• Line#2: Invoking string2.split("") to split called string values character by character.

Output

A string can also be subdivided based on any specified word as mentioned in the following example.

string1 = "We are using a split method for converting a string into parts"
print string1.split("for")

• Line#1: Defining a string string1.
• Line#2: Invokling string1.split() with argument "for" to split when "for" will be encountered.
