Most importantly, it is the entry point for all of the Reflection APIs. which provides methods to examine the runtime properties of the object including its members and type information.Ĭlass also provides the ability to create new classes and objects. In order to reflect a Java class, we first need to create an object of Class.

Could you post some code and please precise if you are using JDK or Android SDK in your program as this could explain why you get a ClassNotFoundException.
The only difference beeing the fact that isInterface will return true. There is a fixed set of primitive types: boolean, byte, short, int, long, char, float, and double.įor every type of object, the Java virtual machine instantiates an immutable instance of You should be able to explore an interface in the same way as you would explore a class using reflection. , all of the wrapper classes for primitive types such as ) as well as interfaces are all reference types. Classes, enums, and arrays (which all inherit from We can understand it like suppose we have a class at runtime. Method Name: getName Count Annotations: 1 Annotation Name: .XmlElement Annotation Simple Name: XmlElement Annotation Modifier: public abstract interface Method Name: getId Count Annotations: 1 Annotation Name:. It also provides an alternate means of obtaining attributes for the parameter. Get The Method: Next, we get the required methods from the StudentDetails class with the Class Object we created.
Well cover two different scenarios: The static method is public. So to invoke the Static Methods of StudentDetails Class without creating an instance we follow the steps highlighted below: Create a Class Object: We create a Class Object of Type StudentDetails using the.

The Parameter class helps to get information about method parameters, including name and modifiers, etc. In this quick tutorial, well discuss how to invoke a static method in Java by using the Reflection API. Every type is either a reference or a primitive. Use reflection with care and measure its impact on your code performance, if you write time-critical part of your app. In Java 8 version, Java added a new class named Parameter to get information about method parameters.
