Understanding Class Literals in Java

The Java programming language offers a unique type of literal known as a class literal. As its name suggests, a class literal represents a type or class itself. It is formed by appending the ".class" extension to the type name.

For instance, the class literal "String.class" refers to the object of type Class that embodies the String type. This object provides various capabilities related to reflection, allowing developers to access metadata and manipulate classes at runtime.

Assigning Class Literals to Variables

Class literals can be assigned to variables of type Class. This type represents the metadata and functionality associated with a class. By assigning a class literal to a Class variable, you can access and manipulate information about that particular type.

Example

To demonstrate the use of class literals, consider the following code:

<code class="java">Class<String> c = String.class;</code>

In this example, we create a Class variable named "c" and assign it the class literal "String.class". The variable "c" now holds a reference to the Class object representing the String type. Using this variable, we can access methods provided by the Class type, such as:

• getName(): Returns the fully qualified name of the class.
• getMethods(): Returns an array of Method objects representing the methods declared in the class.
• getConstructors(): Returns an array of Constructor objects representing the constructors of the class.
