We will get the metadata of below class named Guru99Base. Public Class getInterfaces() : Returns an array of interfaces implemented by the specified class.public Class getSuperclass(): Returns the super class reference.If you want to open a file from the command line or a prompt, use the cd command to move to the folder and open your Java file as you would open a text file. You should use the path of the file on the CD. Public String getName (): Returns the name of the class. For example, one could use: -build-args -H:ResourceConfigurationFilesresources-config.json, -H:ReflectionConfigurationFilesreflection-config.json in order to ensure that various resources are included and additional reflection is registered. A Java file located on a CD should be opened the same way as a Java file on a hard disk.Modifier: This class is used to gather information about a particular access modifier.Constructor: This class is used to gather declarative information such as access modifier, name and parameter types of a constructor. ![]() Method: This class is used to gather declarative information such as access modifier, return type, name, parameter types and exception type of a method.Field: This class is used to gather declarative information such as datatype, access modifier, name and value of a variable.Example 4: How to get Metadata of Constructorsįollowing is a list of various Java classes in to implement reflection.Example 3: How to get Metadata of Method.Example 2: How to get Metadata of Variable.Example 1: How to get Metadata of Class.How to get complete information about a class.The package provides many classes to implement reflection java.Methods of the class is used to gather the complete metadata of a particular class. In addition, Java reflection is also unable to recover runtime type info of Java types that are generic at compile-time a restriction that carried through to. One advantage of reflection API in Java is, it can manipulate private members of the class too. Reflection API in Java is used to manipulate class and its members which include fields, methods, constructor, etc. Java Reflection is the process of analyzing and modifying all the capabilities of a class at runtime.
