The Java String API provides some useful methods to evaluate regular expressions against a text represented by the String
object. Let's list those methods from the String
class:
Method Signature | Purpose |
boolean matches(String regex) | Matches the given regular expression against the string that the method is invoked on and returns true/false, indicating whether the match is successful (true) or not (false). |
String | Replaces each substring of the subject string that matches the given regular expression with the replacement string and returns the new string with the replaced content. |
String | This method does the same as the previous one with the exception that it replaces only the first substring of the subject string that matches the given regular expression with the replacement string and returns the new string with the replaced content. |
