For primitive types and arrays, we can use static variable class. We can get Class of an object using three methods - through static variable class, using getClass() method of object and (String full圜lassifiedClassName). Let’s look at some of the important refection methods for classes. Package class ConcreteClass extends BaseClass implements BaseInterface In this section, we will look into important methods of Class, for convenience, I am creating some classes and interfaces with inheritance hierarchy. For every type of object, JVM instantiates an immutable instance of that provides methods to examine the runtime properties of the object and create new objects, invoke its method and get/set object fields. is the entry point for all the reflection operations. Primitive types are - boolean, byte, short, int, long, char, float, and double. All the classes, enums, arrays are reference types and inherit from. In java, every object is either a primitive type or reference.
