Groovier: Drop or take characters from String in Groovy

Groovy String

Groovy has added many methods in String class which can be used to drop or take part of String from begining of the String.

def str = "Groovy is awesome !"

assert "is awesome !" ==  str.drop(7)

assert "s awesome !" == str.dropWhile { it != 's'}

assert "Groovy" ==  str.take(6)

//Keep taking the string until character ! is reached.
assert "Groovy is awesome " == str.takeWhile  { it != '!'}
