java.lang.Class

The `java.lang.Class` is crucial for reflection in Java, as it represents all types of objects in the JVM, enabling runtime type examination, including member and type information. The class object can be obtained from an instance via the `getClass()` method or using the `.class` syntax for primitives and arrays. If no instance is available, the class can be retrieved using `Class.forName()` with the fully qualified type name. These methods facilitate detailed type information retrieval for objects, primitives, and arrays.
