Scala Strings are one of the most important features of scala. Basically, it is a sequence of characters that uses the linear approach to store data. In scala, the string is immutable in nature and hence we cannot change its original state. Scala language provides us various methods to play with strings we can use these methods on strings to get the desired output. If you want to know about these methods then this blog is for you.

Scala string method for splitting a string
split
In Scala, we can use the split method to split strings into an array of strings. The split method uses specific separators such as commas to separate strings. Let’s see how the split method work using the below example.

The output of the above code is

Scala string methods for Comparing Strings
There are various built-in methods in scala for string comparison like matches,
, equals. Let us discuss what are these methods and how they work.equalsIgnoreCase
matches
This built-in method is used to match regular expressions with an entire string. It returns true if the string matches and false if it doesn’t match. Let’s see how the matches method work using the below example.

The output of the above code is

equals
The equals
the method work similarly to ‘==’. It returns true when both values are identical and returns false when both values are not identical.Let’s see how the equals
method work using the below example.

The output of the above code is

equalsIgnoreCase
The equalsIgnoreCase
the method work similarly to equals method. The only difference between these methods is that equalsIgnoreCase
is ignoring case sensitivity. It means for equalsIgnoreCase
“a” and “A” are the same. Let’s see how the
method work using the below example.equalsIgnoreCase

The output of the above code is

Scala string method for replacing Patterns in Strings
replaceFirst
The replaceFirst
method is used to replace the first matching occurrence of an expression in a string. Let’s see how the
method work using the below example.replaceFirst

The output of the above code is

replaceAll
The
method is used to replace all matching occurrences of an expression in a string. Let’s see how the replaceAll
method work using the below example.replaceFirst

The output of the above code is

Conclusion
In this blog, we get to know about various methods in scala which we can perform on a string to get desired output.
