Java String - Example of Declaring and Initializing Strings and calling Methods - Java Tutorial

Показать описание

The String data type is for declaring a sequence of characters. String literals are enclosed in double quotes, such as “Java”. A String can be any combination of characters including an empty String, a blank, numbers, digits, symbols and escape characters.

String is a class data type, not one of the 8 primitive data types, which means that Strings are objects and not variables.
An object consists of data that belongs to the object, and methods (actions) that the object can do.
