In Java, unlike C, an array of char
is not a String
(§20.12), and neither a String
nor an array of char
is terminated by '\u0000'
(the NUL character).
A Java String
object is immutable, that is, its contents never change, while an array of char
has mutable elements. The method toCharArray
in class String
returns an array of characters containing the same character sequence as a String
. The class StringBuffer
implements useful methods on mutable arrays of characters (§20.13).
