Scala String can be defined as a sequence of characters. Today we will look into String concatenation, substring and some other Scala string functions. Strings in Scala are same as java string and hence the value is of type java. Java classes are available in Scala, hence Scala makes use of java strings without creating a separate string class.

Similar to Java, String is immutable in Scala i.

If we need to append to the original string, StringBuilder class is available in scala. The methods used to obtain information about an object are known as accessor methods. The length method is one of the accessor methods which returns the number of characters in the string. Output : Concatenated String is : String concatenation can be done using concat method.

The concat method accepts a string that is to be concatenated. The printf and format methods are used to format the output numbers. The String class has format which returns a String object. Output : The value of the float variable is Output : Chris Harris, Your email address will not be published. I would love to connect with you personally.

The delimiters can be a character or an array of characters or an array of strings. Or you can also say that it returns a string array which contains the substrings in the current instance that are delimited by elements of a specified string or Unicode character array. There are 6 methods in the overload list of this method as follows:. This method is used to splits a string into a maximum number of substrings based on the strings in an array.

Scala Slice: Substring, List Slice

You can specify whether the substrings include empty array elements. Return: This method returns an array whose elements contain the substrings in this string which are delimited by one or more characters in the separator. This method is used to splits a string into a maximum number of substrings based on the characters in an array. Return: It is an array whose elements contain the substrings in this string that are delimited by one or more characters in the separator.

This method is used to splits a string into substrings based on the strings in an array. Returns: This method returns an array of strings whose elements contain the substrings in this string that are delimited by one or more characters in the separator. Exception: This method will give ArgumentException if the options parameter is not one of the StringSplitOptions values. This method is used to splits a string into substrings that are based on the characters in an array.

Here, separator is a character array that delimits the substrings in this string, an empty array that contains no delimiters, or null. Returns: It returns an array of string whose elements contain the substrings in this string that are delimited by one or more characters in the separator.

This method is used to splits a string into substrings based on the characters in an array. Returns: This method returns an array whose elements contain the substrings in this string that are delimited by one or more characters in the separator.

You also specify the maximum number of substrings to return. Returns: This method returns an array whose elements contain the substrings in this instance that are delimited by one or more characters in the separator.

Scala - Strings

You want to split a string into parts based on a field separator, such as a string you get from a CSV or pipe-delimited file. The split method returns an array of String elements, which you can then treat as a normal Scala Array :. The string that the split method takes can be a regular expression, so you can split a string on simple characters like a comma in a CSV file:.

Use the map method to call trim on each string before returning the array:. You can also split a string based on a regular expression. This example shows how to split a string on whitespace characters:.

Zen Foundation business card.StrSplit method allows you to break a string based on specific delimiter. If it is omitted or zero, it will return all the strings matching a regex. Here if we want all individual strings, the best possible pattern would be to split it based on the comma.

So we will get five separate strings as follows: Alpha Beta Gamma Delta Sigma Use the split method against the string that needs to be divided and provide the separator as an argument. In this case, the separator is a commaand the result of the split operation will give you an array split. An output something like this- Alpha Beta Delta, Gamma, Sigma This can be achieved by passing another argument along with the split operation, and that will be the limit of strings required.
