Most of the time, if you are using a single character value, you will use the primitive char type. // unicode for uppercase greek omega character char unichar = "\u03a9"; // an array of chars char[] chararray = { "a", "b", "c", "d", "e" }; There are times, however, when you need to use a char as an object for example, as a method argument where an object is expected. The java programming language provides a wrapper class that wraps the charin a character object for this purpose. An object of type character contains a single field, whose type is char.
