STRING

What is a String?
A string is a sequence of characters — like letters, numbers, or symbols — grouped together as text. In programming, strings are used to store and work with text.

Java string is a sequence of characters that exists as an object of the class java.lang. Java strings are created and manipulated through the string class. Once created, a string is immutable -- its value cannot be changed.

A string is sequence of characters. A class is a user-defined template for creating an object. A string class is a user-defined template for creating and manipulating string objects, which are sequences of characters.

*They can include letters, digits, and symbols.
