Groovy adds a lot of methods to the Java String class. For example we can use the take method to get a certain number of characters from the start of a string value. With the drop method we remove a given number of characters from the start of the string. In Groovy 3 we can now also take and drop a certain number of characters from the end of a string using the methods takeRight and dropRight.
In the following example we see how we can use the methods:
1 2 3 4 5 6 7 8 9 10 11 12 13 | def s = "Groovy rocks!"// Drop first 7 characters.assert s.drop(7) == "rocks!"// Drop last 7 characters.assert s.dropRight(7) == "Groovy"// Take first 6 characters.assert s.take(6) == "Groovy"// Take last 6 characters.assert s.takeRight(6) == "rocks!" |
