Java String
In this section, you will learn about the java string. Java String is a set of characters such as the string
"Hello". It is a combination of H, e, l, l, o. All String
literals are instances of this class and two string literals with the same
contents refer to the same String object. A string can store a single word or
more.
The String class includes number of methods to edit the
content of string. String is special-cased when doing data serialization -
rather than listing the fields of this class, a String object is converted to a
string literal in the object stream.
The Java String object contains a sequence of char
values. A char represents a single character, such as 'a', 'A'. A char
value is written in Java code using single quotes (') as shown here. Java
supports the Unicode character set, so we are no limited to just roman A-Z
characters. The char data type is a simple primitive data type, this is very
similar to int, so use simple = to copy char values, and == and != to
compare char values.
For creating a String object you use the "new" operator:
String str = new String("Hello");
