In Java, strings are represented as objects of the String class. The String class is part of the java.lang package and represents a sequence of characters.
A String object is immutable, which means that once it is created, its value cannot be changed. Instead, you can create a new String object with a different value.
Here's an example of how to create and use a String object in Java:
String s = "Hello, world!"; System.out.println(s); // prints "Hello, world!"
You can find more information about the String class and examples of how to use it in the Java documentation.
