To replace all matches, we use replaceAllIn(). To replace a first match, we use the method replaceFirstIn(). Here, we use the Regex() constructor to create the pattern, the method findAllIn() to find all occurrences of the word, and a pipe(|) to allow any case of a certain letter. Scala> (word findAllIn str).mkString(", ") Scala> val str="An intern on the Internet" Let’s take another example of Scala Regex. For a string with multiple occurrences, we can use findAllIn() to find all occurrences. Then, we call the method findFirstIn() to find the first match. We define a word and a string to search in. Here, Scala converts the String to a RichString and invokes r() for an instance of Regex. Str: String = Scala is a portmanteau of scalable and language Scala> val str=" Scala is a portmanteau of scalable and language" Let’s Discuss Scala Closures with Examples scala> val word="portmanteau".r We import the Regex class from the package. Using certain strings, we can find patterns and lack of patterns in data.’ To convert a string into a regular expression, use the. So, let’s begin Scala Regular Expression (Regex).
